Toggle pressure

[Nidaho 0]

After a long layoff from an accident and loss of some upper body strength, a friend wants to get back into jumping. Can anyone tell me how much toggle pressure (in Lbs) there would be on a Triathalon 135 at about 1/1 wing loading?

Not sure but since they got hurt on their last jump and have less upper body strength maybe they should jump something a little bigger than a 135

Depends on too many factors. Toggle pressure to flare after a straight in approach is one thing, but what about flaring after a low turn that picked up a bunch of speed? I don't think you'll be able to find one magic number. Start big, work down slowly.

Responses so far tend to be 'start big', which may be entirely appropriate when the person is very uncurrent or dealing with other aspects of injury recovery.

But for low toggle pressure alone, starting small is good. Small sensitive canopies also turn easier, so there's less toggle input and thus less force is needed for a given turn.

But I don't know about that canopy specifically. Find someone else to try it out?

(Edit: After a recent non-skydiving elbow injury, my first jump back was on a really big canopy. Mistake - too much toggle pressure. As soon as I went back to my little crossbraced canopy it was fine. But it does help to know where one's weaknesses lie before jumping something too fast.)

Previously jumping a < than 105 canopy, thought a 135 was being conservative. Input appreciated.

Does "your friend" have a PT? There are some great exercises that can help simulate a toggle stroke. Typically you can use PT exercise bands for this function, wrapped around a pull up bar. You can also use a pulley/cable machine with the rope attachment for the same movements.

Train for more than you need, since every reserve I've ever jumped had a higher toggle pressure than the main!
