All AFF includes a small element of canopy but the point is that it is insufficient. Asking lots of questions is great for all aspects of development but poor canopy skills are rife amongst fresh jumpers. The option should atleast exist for a student to opt for an additional one or two jumps just on canopy control, this is not the case at the moment.
-
I started to have problems with off-heading openings and the canopy doing lots of unpredictable things. I realised that it was because i was looking up at the canopy opening far too early. When i went back to a totally controlled, horizon-gazing position the problem vanished. I also recommend a haky-sack throw out as I understand it reduces burble due to the fact it can be thrown further out (i previously had a soft handle- totally crap!)
-
The argument i hear is that the average injured jumper has 1000 jumps (2002 anyway) but if these skills were drilled into you at the start like the principle of 'pull and flare' then the discipline is with you for life.
-
Why is it that there is not more emphasis on canopy control for AFF students. Shouldn't there be atleast one more level to cover canopy control to reduce the number of landing injuries? Is this being considered?

The point is that to rely on just one piece of equipment is a risky business if for no other reason than because all equipment is liable to failure. My advice for what its worth is to use a mechanical alti and an audible for flexibility and safety. Belt and braces... By the way which Regt.?
-
Well explained! That does help.

I hope that you're ready for this... The altimeter works on the principle that the pressure within a column of air decreases in a known way with height. For the scientifically inclined, the relationship is z = (RT/gM).loge(po/p) where z is the height difference between the starting height and the measurement height, R is the gas constant, T is temperature of the air in degrees Kelvin, g is the acceleration due to gravity, M is the molar mass of the gas (in this case air), po is the atmospheric pressure at the starting height and p is the atmospheric pressure at the measurement height. Electronic altimeters have this relationship programmed into the chip. Happy?
-
One of the problems of this type of barometer style equipment is that air pressure doesn't change uniformly with altitute. The atmosphere creates a loss of 2 degrees per thousand feet barometric, but in reality the temperature can be the same for several thousand feet in freefall which will falsify the alti reading so you need to either have an audible or keep an eye on the ground!!
-
that sounds interesting, is the main benefit for speed of packing? doesn't that create harder openings?
-
Clear flaps sounds like a good idea but i don't think that there is any substitute for a physical check of your pins. By checking the pins you are also checking the area around the pin like the bridle and the way it is stowed.
-
How do you get away with not stowing your lines? How do you get the bag closed?? If you leave the lines free how do you prevent massive line complications?
-
can you tell me what a linedump is and why its such a problem?
-
sounds like good advice, i'll try keeping the stows small and tight......Much appreciated!
-
I'm not sure what a 3 locking stow dbag is?? otherwise, I always pack in exactly the same way (give or take) I'll give it try by changing direction but it seems a little unlikely...
-
around 80. The problem is quite recent..
-
the bites are quite small but the rubber bands are different and I don't do them up tight..
-
I have around 100 jumps on an exe 185 and seem to get line twists quite regularly. I have paid some attention to my body position and packing but I can't seem to figure it out, anyone?
