Introduction
The following ‘Adaptive’ system (c) 07 is intended as a method to transition persons with leg control issues, such as paraplegics, into being fully capable SOLO skydivers. The Adaptive system© suggests the use of special purpose equipment, which serves to overcome some of the barriers associated with leg disabilities. The adaptive system highly recommends the use of the best practices used by able body persons, such as tandem skydiving, vertical wind tunnel training, Accelerated Freefall and Progressive Freefall.
The tandem skydiving system was developed as a relatively safe and controlled alternative student method, whereby the passenger/student is securely strapped to a highly experienced instructor during the entire freefall and parachuting event. The tandem system is also used to accommodate persons of various students disabilities, wanting to enjoy the thrill of skydiving, where previously it may not have been possible. Although the Tandem method has proven to be reliable for overcoming the limitations of a student’s disabilities, it alone does not allow a student to progress to solo freefall.
Vertical wind tunnels (freefall simulators) are being used throughout the world as training bases for novice, intermediate and highly experienced skydivers. The tunnel provides a stress free (no worrying about opening and landing a parachute) and controlled environment in which to introduce a novice skydiver to the mechanics of body flight. It also allows very close scrutiny of the student during all freefall activity. Skill development is greatly enhanced and accelerated when using a wind tunnel. Tunnel training is HIGHLY recommended for persons with any disabilities, as it allows the instructor and the student to assess the effect(s) that a disability may cause in a freefall situation. It also allows any special actions, procedures and equipment to be developed in a short amount of time, without a great amount of risk.
The Adaptive Freefall Program© is intended as a supplement to existing conventional student freefall training methods such as AFF, PFF or Tandem Hybrid programs. This Adaptive program© is based on information collected from instructors and students that have developed their own techniques through trial and error.
The information contained in this document has been collected from various
sources, but under no circumstances should it be considered the definitive document.
There is no substitute for experience. Only HIGHLY qualified and experienced
instructors should attempt to train disabled students for solo freefall.

(Liability)Adapt a Waiver for the Students with Disabilities: This point has been brought to my attention by Fred Well do you or do you not have students and Tandem Passengers Sign a waiver? This sign their rights away against any mishaps. a waiver for a disabled student may have to be reworded with the additions of the "Jack Knife" or "Landing mishaps" that could be a possibility. I'm putting out there to any lawyer skydivers to construct a Waiver designed to or for a student who is disabled. So that the DZ and Tandem Master do not feel threatened. We get regular Students signing their lives away why can we not make waiver that is specific to a disabled Student? This is so I can put up with this Manual an example of a waiver. thanks Fred.
I’m not putting restrictions on this manual but it’s mainly designed for paraplegics with upper body mobility or head injury or stroke victims, that have cognitive ability to perceive and comprehend all that is taught or exercises that need to be completed in physical and mental abilities. You may require a letter from a neurological DR saying that the cognitive ability to fully comprehend what they are getting into and the dangers and possibilities and the comprehension of the waiver they will be signing (signing your life away)
Just so the awareness is there a student needs to have allot of upper body mobility and strength. So this progression is not for all disabled, it’s for disabled persons with allot of upper body control so IE: Paraplegics with upper body fine mobility are a key student this progression is aimed at the adaptive. We are not discriminating against those who don’t there just is a minimum strength and mobility with upper arms that is required as a minimum. So it will be up to the current instructor in Disabled skydiving that will assess a, persons student qualifications. Please realize there is a minimum physical ability and mental ability (awareness) required to make a safe skydive other wise I suggest doing just a tandem (With the "Mack Straps©"for Tandems) as a passenger for safety reasons but still getting the positive feeling of the sport.
So I’m starting a new book with the potential of a new and pioneering way that Adaptive(disabled) people can take a structured progression to skydive by themselves I was once an international skydiver but had a bad landing that put me on ground zero again. So I’m now trying to devise a way of a structured progression for Adaptive (disabled) people to skydive on their own. I’m suffering from right side paralysis and some brain damage. So I’m coming from an experienced instructor in the CSPA instruction system. So I’m starting off from square one. I’m being helped into achieving my goal of being able to jump by myself again. So I’m going to write about how as an instructor that use to be and now from a disabled (Adaptive) person now.
Well: I realize that this may not be a money making position because of all the time needed to accommodate an Adaptive Student. So I'm putting this out there for instructors (A suggestion, outside instructor harness grip on student and foot on the step leaning on the strut, in plane instructor sitting legs out, and if possible pull the student up on their lap and in co-ordination with the outside instructor, 1,2,3, lift up and out away from the step) that would like to help and push their own experiences to the limit and learn in the process. I think it would be a progressive way to enable the disabled with good upper body co-ordination. As it is an important part of this system. Someone with the experience and teaching ability could teach this type of disabled Tandems and PFF/AFF progression but as I've said it will take more time and effort so it might not be for every DZ. DZ'ds with larger planes and more experienced instructors it could work. Or even the military could maybe take this on too. It will take some experienced instructors and tandem instructors to make this work in a progressive way.
Please Note:
Please note that all Adaptive athletes are all individuals. Each Student will have to be assessed I suggest in a wind tunnel. If a wind tunnel is not accessible then have the Instructor to take them on a tandem jump and asses them for freefall. But a wind tunnel would be the optimum place to do a freefall evaluation being able to see how they would be not strapped to a tandem master. So if you are assigned as the instructor dealing with the Adaptive Skydive Program, we suggest doing the evaluation in a wind tunnel for optimum observation to access. All Adaptive athletes will all have various ways they adapt to a PFF freefall position. Some have to be aware that Paraplegics get uncontrolled leg spasms. This has to be taken into consideration for the Adaptive PFF Program.
Training Phases
The following phases of training are considered essential in establishing the feasibility of each individual’s freefall abilities:
Tandem Training: The tandem jump phase is intended to introduce and familiarize the student with the various aspects of a freefall jump (plane ride, exit, stable freefall, canopy deployment, canopy decent and landing). The total quantity of tandem jumps should be at the instructor’s discretion, as the student must display the freefall awareness and canopy control skills necessary to allow them to progress to the instructor assisted freefall training program (AFF, PFF, etc…). It will be necessary to have the student participate in the first jump course after completion of the introductory tandem jump. The objectives of the tandem training phase are as follows:
- Aircraft familiarization (see below)
- Stable body position on exit
- Stable and relaxed body position during freefall (wind tunnel training suggested)
- Altitude awareness
- Canopy deployment at a predetermined altitude (AFF/PFF instruction)
- The ability to recognize a functioning canopy (observation of this is required)
- Ability to locate emergency handles (upper body mobility)
- Adequate canopy control
- Landing area navigational skills and hazard recognition (cog native ability)
- Acceptable flight patterns, including wind direction awareness
- Adequate landing technique (each situation should be evaluated)
It should be noted that an emphasis should be placed upon canopy and landing skills, as the repercussions of an off-site or hard landing are much more serious than that of a person with full leg use and mobility.
At some point in the tandem phase, it is recommended that the special equipment described above is introduced and utilized. This will allow the student and instructor to become familiar with the idiosyncrasies of the equipment prior to them being used in the solo jump phase.
Note: The tandem jumps do not necessarily need to be completed prior to the wind tunnel training. It may be advisable to conduct the wind tunnel training immediately after the introductory tandem jump and upon a student’s decision to proceed with freefall training. Another thought is to split the tandem phase into two portions (freefall introduction and advanced canopy control), so that the student is more current with their canopy control techniques just prior to their solo jump training.
Wind Tunnel Training: The wind tunnel is an essential tool for safely determining a disabled student’s abilities in freefall. The wind tunnel is a freefall simulator, which provides a controlled ‘laboratory’ environment in which to develop a student’s ability to maintain stability. The result of the tunnel training may show that the student’s abilities are such that they should NOT proceed with solo freefall, due to safety concerns. Look also at trying out the freefall jumpsuit or pants desired for the Stages of wind tunnel and freefall.
Freefall stability training should place emphasis on being relaxed. As with any student, relaxation of the body is the key to achieving a neutral, stable freefall position. It is much more important with persons that rely mostly on the use of their torso and arms for freefall control.
It is recommended that at least two qualified instructors are present in the tunnel during the stability training, in order to safely contain the student’s unintentional movements and to adequately observe the student’s body positions and reactions.
As in freefall, wind noise eliminates verbal communication capability; therefore predetermined hand signals MUST be worked out and practiced prior to entering the tunnel for the first time. These signals should be simple and allow the student to fully understand entirely what the instructor is requesting. There should also be signals between the instructors that allow them to communicate each other’s intension's.
The wind tunnel activities should be as follows:
- Low air speed introduction. This allows the student to familiarize
themselves with the effects of their actions, with respect to the airflow, without
having a drastic sudden response.
- Increasing air speed stability development.
The student’s progress should determine the rate and amount that the air
speed should be increased. The air speed is to be increased as the student has
demonstrated the ability to remain in control at the current speed. Continue
to increase the air speed until normal freefall air speeds are achieved (approx.
120 mph).
- Full independent stability. The target for
the students is to independently (unassisted) control themselves, in the tunnel,
at full air speed.
- Tunnel training periods should be limited to 15-minute increments,
in order to verbally debrief the activities. I would suggest that between two
and four, 15-minute periods would suffice for the student to accomplish the
basic stability requirements.
- Once reliable stability is achieved, freefall
exercises may be introduced. It is recommended that the student and instructors
rehearse the activities that will be introduced during the solo training (such
as AFF/PFF Level 1, 2, 3….). It is also recommended that ‘jump timing’
be introduced into the tunnel training. This will help prepare the student for
the altitude awareness skills that will be absolutely required in the solo training.
The AFF/PFF style clock altimeter can be used for this purpose. If the 15-minute
period is utilized for these exercises, then it is best to repeat a single dive
multiple times rather than exercising multiple dives during a single tunnel
session.
- Parachute deployment exercises are also recommended
to ensure that the student understands the requirements for maintaining a stable
reliable deployment sequence. A pilot chute simulator (strap on handle) is recommended,
as long as it is effective in demonstrating realistic deployment technique.
It is advisable to increase the student’s deployment altitude by at least
1000’ in order to compensate for the added complexities of their equipment
(leg lifting straps, knee braces).
Freefall Training: Once the student
has fully demonstrated, in the wind tunnel, their abilities
to maintain stability and to perform the basic requirements of solo training,
then they are ready to progress to the solo training stage. It should be noted
that the time period between they tunnel training and the solo training should
be kept to a minimum, in order to keep the skill and muscle memory advantages.
It is also recommended that a tandem jump be completed just prior to conducting
the first solo training jumps. Keep CURRENT on all skills!!!
Stage 1) the first move I will make is getting a DR’s
notice that I will not have another brain injury if I’m involved in a
hard parachute opening. As I had some very little brain stem damage and there
is little known about brain injury’s and there affect with skydiving.
Just check with your DR about outside actors IE: internal, bars or pins that
may be effected on a hard landing that would effect most able body people but
they may have to have a harness that is designed or set of "Mack
Straps"© that would help them get their legs up and out
of the way on landing see Fig 2 for drawing of and idea for the "Mack
Straps"© that works. Before my accident I had done over
300 adaptive tandems where I had to make sure the legs positions were in such
a way there was no danger to the passenger in free fall or on a regular or bum
slide landing. Also something that has been put in the public eye now due to
an accident is the possibility of an adaptive passenger with little leg control
may slip out of the harness due to a hard enough opening. So there is a modification
that is out there for a student tandem harness I also have an idea for or to
modify an already existing harness.
Student skydivers are taught stability by holding an arched body position as follows:
- Hips pushed forward (arched)(wind tunnel or creeper demo)
- Head held back
- Arms outstretched and pulled back
- Knees bent at approximately 90 degrees
- Legs held wide apart
Lack of leg control in freefall presents a two-fold problem. Firstly legs are a significant control surface for freefall, so without control over the legs, a skydiver is at a disadvantage. Also, if the legs are unrestrained, they become a detriment to achieving and maintaining freefall stability. In order to overcome the lack of leg control, specially developed equipment may be necessary to achieve the knee and leg positions described above.
It should be noted that an emphasis should be placed upon canopy and landing skills, as the repercussions of an off-site or hard landing are much more serious than that of a person with full leg use and mobility.
At some point in the Tandem phase, it is recommended that the special equipment described above is introduced and utilized. This will allow the student and instructor to become familiar with the idiosyncrasies of the equipment prior to them being used in the solo jump phase.
Note: The tandem jumps do not necessarily need to be completed prior to the wind tunnel training. It may be advisable to conduct the wind tunnel training immediately after the introductory tandem jump and upon a student’s decision to proceed with freefall training. Another thought is to split the tandem phase into two portions (freefall introduction and advanced canopy control), so that the student is more current with their canopy control techniques just prior to their solo jump training.
Leg Braces: There are some commercially available leg/knee braces available that have adjustable knee angle brackets. The adjustable braces are ideal for determining each particular student’s neutral knee angle. It may be required, depending on the student’s tendencies, to make the knee position slightly more OR less than 90 degrees. The adjustable units are acceptable in the initial development phases of the student training, but it is highly advisable that they commission custom built FIXED angle braces. The custom built braces should have the following features:("Mack Straps©" are designed in such a way to go over braces as well)
- Rigid, protective shell, constructed from custom molded fiberglass, rigid
plastic or carbon fibre, etc. This rigid shell provides the means to hold the
legs in the required knee bent position, as well as providing some degree of
leg protection, in the event of a harder than normal landing
- Padded, custom fit, soft liner, which is comfortable against the legs. An
impact absorbing foam, together with cotton covering is recommended.
- Wide, easily accessible tightening straps. These straps should be reliable
and as simple as possible. Velcro is recommended, in order to avoid the use
of protruding metal hardware.
The construction method described above is similar to the methods employed in any commercially available protective helmet (Protec, etc.). The leg braces should be worn under a suitable pair of pants or jumpsuit, in order to avoid snags and damage.
Refer to the photos below for some detailed examples of these types of braces.
Stage 2) The student should first take the standard first jump
course for other student jumping information to fill in all questions and make
sure they are ready to start with a disabled (adaptive) Progression which is
very much the same in most respects but more like and eventually go to a PFF
jump or AFF stage 1 after all the tandem jumps have been completed up to a proper
level of awareness and ability.
Tandem Jump 1 Stage 3) First, jump tandem this is to determine how your body can react in free fall so always take video of the free fall and opening to see how your body reacts in free fall. If your body position is stable, in free fall as a tandem passenger good. If your legs move uncontrollably in free fall then there are ways and adjustable straps that are available to make your legs more stable in free fall examine the video and take notes on any problems there are and how to correct them. Talk to an instructor about what could appear to be some difficulties free fall. Also look at your body position on when the parachute opens and see if there is a shift of body position in the harness as you go from over 100 MPH to 0 in a matter of seconds and the forces may vary from person to person. Try to look ahead and fix some or all of the observed problems before the next jump. Practice use of the "Mack Straps©" too. Pulling legs up and out of the way For a safe Tandem Instructor to land.
Tandem Jump 2Stage 4) the second tandem jump video it for sure see if the solutions to earlier problems have been resolved in the video after the second jump. On the second jump have the student do fake training pulls by having a piece of paper in their harness to make a training pull and see on video if it is preformed the correct way. Brief the student also not to try to grab or pull anything on the tandem instructors’ harness this should be practiced on the ground till it is like a second nature or natural movement for the adaptive student.
Tandem Jump 3 Stage 5).There should be 3 repeats of the second
jump with practice pulls and video debriefing after all to see any visible things
in arm movement or free fall position to correct.
Stage 6) This the practice tandem harness should have a dummy cutaway and reserve handle so after being thoroughly briefed in the class room on a hang harness set up and practice a reserve activation procedure like a normal student would do. On opening of the tandem jump the student should do a practice pull of cutaway and reserve handle in proper order. And able to put handles into their jump suit as a normal free fall student is trained to do. If the disabled (adaptive) student can only use one arm in a fast motion such as a head or stroke victim then on the ground in the class room it should be practiced in a way that the student practices using a one arm motion for both handles sometimes difficult but with practice it will become more of a natural movement This should be determined in the hang harness on the ground before the next practice jump The Student should do at least 3 jumps this way videoed and debriefed for each jump with a qualified tandem instructor or first jump instructor. The student must prove to the tandem instructor that he/she is able to steer in a correct manner and flare the parachute at the correct moment before landing and that on at least 3 jumps the inflatable rubber butt pad used by adaptive students is properly inflated and set up by the student for landing in the proper manner
Tandem Jump 4 Stage 5).After proving all the actions on these jumps and it’s in the best interest and safety of the instructors and student a stage 1 PFF /AFF can be fully trained and attempted and briefed to the student. A final written test shall be given to the student to see he/she is fully prepared and aware of what is expected the student is to complete in the PFF section of the disabled progression in skydiving. Both PFF instructors should be briefed in the disability of the student and what he/she needs to be looking for and be able to signal how to correct it in the free fall part of stage 1. The student is to be equip with a ground to student radio so that they can hear a direct instructional instructions from the ground instructor to make sure that the student does not miss all the equipment he/she has to see is fully put in place before landing as there are allot of equipment to be in place for this adaptive student must be aware of or reminded of for a safe landing after stage 1 PFF.
Tandem student Landing awareness: A well planned approach
makes good landings easier to accomplish, while most bad landings come after
a poor approach. It follows then, that working on improving a variety of approach
techniques is the first step. Control your canopy with smooth toggle movements.
You may not even realize how slow you can approach and still be safe. Its better
to practice in good conditions so that you are prepared for the worst. Most
new canopies can be flown straight in, even at very high wing-loadings, with
proper technique. If you can’t do it, you probably need to work on technique.
Stay with straight-in approaches, working on flaring technique for many jumps
to obtain the longest swoop possible before attempting any turning approaches,
you should, work on technique. Over a period of many jumps, find out how much
you can vary the altitude loss in a turn by using different control inputs In
these experiments you will find that some techniques will produce extremely
high altitude loss with only a moderate rate of turn (Example: Steep front riser
spiral). Starting real high and knowing many turning techniques allows you to
have plenty of outs. Try to start all your turning approaches with enough altitude
to make the high altitude loss turn safe. Choose the turning method you feel
is appropriate, for your level of skill or ask an instructor for advice too.
PFF/AFF Stage program and things a student has to achieve. After, fully passing
all Tandem free fall and equipment requirements.
Modified Exit Position: (for a cessna),Because the student can not do a poised exit a modified position for exit into the PFF/AFF stages will have to be up to the instructors. One would have to be outside the student sitting facing front with the other instructor doing the normal grip. Making sure the Students legs are clear of the step to avoid a mishap or connection with the plane that will happier the exit. Or a one movement "Go!" Where both instructors leave launching the student and using their holds to get the student into the correct free fall body position. Then follow the jump situations to continue. Also make sure instructors and student debrief with the video. Making sure there are no problems that need to be addressed. The exit will have to be a feel thing for instructors and student. But making sure of good holds before exits are very important to get the student into a free fall position. For Exiting a Twin otter or bigger aircraft I'm just asking the experienced instructors to accommodate the exit as they best feel possible and safe. Larger aircraft allow for an easier exit plan. Using the harness leg holds, and arm grips getting the student to the door and then as practiced on the ground a singular exit movement by instructors 1.2,3 carrying the student in one motion to stay together out the door into the air force and free fall.
Leg Lifting Mack Straps (to be used for tandem Passengers):(When looking at stage 1 and on please look at the freefall pants design by Angus Smith of Parachutes Toronto,see pictures below) To facilitate smooth landings, it will be necessary to have the student lift their legs up prior to landing, similar to the technique used during tandem jumps. This can only be practical if the student’s hands are free to perform canopy and landing control requirements. A pair of leg lifting straps, with integral tightening hardware (e.g. chest strap Velcro), is a method to achieve this requirement. These "Mack Straps©or the Angus designed freefall pants" are most effective if they are used in freefall. A system that is proposed comprises of "Mack Straps©or the Angus designed freefall pants" are Velcro on, at the knees. The top of the strap has quick connect hardware(Velcro) that allows it to be attached to the chest strap of the parachute harness this way it will not interfere with any Parachute attach or release system. These "Mack Straps©or the Angus designed freefall pants" should be well secured for freefall (velcro or snaps), and be easily accessible once the student is ready to lift their legs.
The use of these "Mack Straps©or the Angus designed freefall pants", and the sequence of there use, should be introduced during the tandem training phase. The leg lifting activity should commence once the canopy and navigation check list has been completed. Namely, the student should FIRST identify that they have a serviceable parachute and that they are in good geographical position for landing at the target before worrying about pulling up their legs for landing. Conversely the student should be trained to complete this activity as SOON as possible, in order to avoid rushing at the last minute before landing.
Refer to the photos below for some detailed examples of these types of leg lifting straps.
Large Parachute: It is imperative that the student is able
to perform low speed landings. This requirement is accepted practice for able-bodied
students, but it is much more critical for student with leg disabilities. In
order to achieve a low speed landing, the parachute size and performance characteristics
must be selected to allow for the parachute loading. Depending on the student’s
weight, it may be necessary to select a parachute that is larger than a conventional
training parachute, such as a tandem parachute. Do NOT take chances with parachute
size!!! Bigger is better!! Saying this, special consideration must be taken
to allow the student to jump in windier conditions. A low weight to parachute
size ratio will decrease the forward air speed and the ability to penetrate
into the wind. Do NOT take chances with wind conditions!!!

Harness Modifications for a Tandem Passenger
This mod could also be done on a adaptive PFF/AFF harness.

More Detailed view





Para Rick's logbook entry before "Jack Knifing" had a name
The safest way is to use my Harness mod with the "Mack Straps©" to secure the guard against a Jack knifing passenger. With this combination the passenger will not go bottom low in the harness. Even with the proven "Mack Straps©" alone have guarded against this body position too. I will be posting a Para Passengers opinion of the "Mack Straps©" and how the on their own guarded against him slipping out and was able even in a deep pike position able to pull himself back up to a point of the Tandem Master able to do a safe landing. As I can see now with the addition of the Mod's from Parachute Toronto. Unseeing an ankle support would be very helpful for landing too.To Act as an ankle support for a slide landing. So look at all the options and use the ones you can.

Technical Information
Mack Strap © System
1) Using the ankle strap should be in place
2) Upper knee Lower thigh strap should be snug.
3) Leg lifting chest strap attachment should be secure
4) Landing Pad and Lower back support secure for free fall.
If any questions on how the "Mack Strap System '91"© should be applied . Just a note, about the leg "Mack Straps©". There was an incident in Victoria BC where Richard a Para tandem passenger (Me Rod C Mack D-422 Tandem instructor) almost jack knifed out through his harness and the "Mack Straps©" he was wearing saved him from falling though the harness. So even using the leg "Mack Straps©" on their, own can help. The "Mack Straps©" are a proven system since 1991 so please if wanting to copy or try it All I ask is you call it the "Mack Straps©". Comment by myself this was before it was called a Jack Knife I said "hey man your body pikes (pike being a gymnastic term as I'm a gymnast too) up weird on opening". I'm getting some signed log book entries to substantiate.
Comments from other Tandem Masters who have experiences to share
1) Sometimes a system that seems to work on the
ground to lift the legs may not work so well in the air. I don't have the experience
to judge how the system "should" work. I've heard of enough cases
where the student manually lifted his legs for landing without using ropes or
anything, but just a strap around the legs. But maybe the recommendation is
to do a hanging harness test to double check that the exact combination of passenger
and straps allows him to lift his legs OK.
2) If you think I'm right about it, there is that point about
joints like ankles being much weaker than the rest of us would imagine,
which adds risk one might not otherwise realize.
"Mack Straps" should only be used to help do disabled Tandems. The Angus designed freefall Pants are more suited for the PFF and Wind Tunnel portion of getting a disabled athelete to solo.

All I had was 36 lbs but it will take more
Just a note, If anyone wishes to buy a set off of me because you may not have access to a commercial sewing machine or the Materials. I will make some for you at a cost of $60.00 ($50.00 to cover cost of materials & labor $10.00 to put towards the RW team fund for the WPC 08)If you wish to order E-Mail Me Rod Mack©
May I suggest if not familiar with how the "Mack Straps©" work put student in a hang harness so they know the look and the tandem Master knows the look and how to lift up legs for a controlled landing hopefully standing up. Doing slide landings is more for the Tandem instructor who is inexperience at using the"Mack Strap©" System. So use a hang harness like you would for any new equipment addition for both student & instructor.
There is a paraplegic in Victoria B.C. Para Rick in Canada who
has preformed over 80 tandems, and experienced potentially
dangerous body positions while skydiving. He has used the “Mack
Straps©” on most of his jumps, and the “Mack
Strap System ‘91”© insures that he will not accidentally
“Jack-knife” out of his harness. He also
had a few times got a bleeding nose from impacting his knees to his face on
opening so he does not grab the harness anymore he puts his hand out on his
knees so as to protect his face. That is where the "Mack
Straps©" effectively keep him in the harness without
"Jack Knifing" out.


This Pulley system works webbing goes around neck and under jump suit for free fall bring let it out of jump suit after opening Then attach Carabineer to "Mack Strap© " Loops then get the passenger to pull legs up into a tuck position and lock them so his/her hands are free to help land.
Instead of a pulley system a simpler way would be to use a 4-6" Carabineer on the chest strap making it easier to lift and lock the legs up so as to help with steering and landing.

"Mack Straps©" Mod for Harness

Landing alternatives: if a ground landing with a foam or padded lower back and tail bone support are unlikely. Then the alternative is a water landing, Pool if canopy control is good or a lake, or the ocean if it is warm enough. Things needed will be a C02 inflatable life jacket so if free fall there is less bulk. A briefing on how to inflate the life jacket maybe practiced in the hang harness. Also if in a lake or the ocean it is recommended that a scuba diver is present in the capture boat in case anything out of the ordinary may happen.So that this into consists an alternative to a ground landing and is much safer too. Please use my manual when you can all i ask is I get credit for the procedures used if used. Also I suggest having elbow pads full face helmet in care a roll is a poss ability
Or some Adaptive skydivers use thier jell padding from the seats of thier chairs. This could be could be good on a not so hard landing you should also wear a lower back brace for any harder impacts. Also use of s good helmet and elbow & knee pads and good gloves to protect all extremities on an unussual landings. So take in all that you have used before in protecting your landings by pads and a Jell pad for your seat. With a lower back support in Neoprene,

If you think a chapter or two could be added then Please do and give yourself credit for the added chapter. One thing I do not have any experience with is a wind tunnel. So if you have experience with the disabled in a wind tunnel that would apply please add and send it to me so I can post it on this site with the manual.
Thanks please use and put North America first in devising a way for the disabled to skydive on their own , all the best
