Parachute Safety
Mid-air collisions between gliders is one hazard of contest flying where the density of gliders is higher. In most collisions at least one or two of the accident pilots are able to safely escape by parachute. As a consequence most private pilots wear a parachute for safety. The parachute is very reliable if the pilot keeps the parachute in good condition. The following procedures are recommended: The FAA regulations require that the parachute be repacked by a certified riggerevery 180 days. The rigger will inform you of the condition of the parachute. Take good care of your parachute, always keep the parachute dry, clean, and the packing in good shape. Never put the parachute on damp ground and keep it out of the rain. At the 2010 SSA Convention Alan Silver, a highly experienced rigger, made the following recommendations for parachute handling: All parachutes should be retired after 20
years. Practice getting in and out of your airplane every
day you fly. Always get three things out of the airplane
in the same order every time. Canopy, Belts, Butt. Don't
leave the parachute leg straps loose pending an
emergency, because of limited time in an emergency.
Practice will cut your ejection time in half and after
structural failure you may be going down fast. Without
practice it takes 15 seconds in a Citabria. Problem
specific to that airplane is that when you release the
door it does not jettison. You have to bang the bottom of
the door or release the top latch and the rear latch
after you pull the emergency pins! Near landing, don't look down after you have determined that you will land at your goal, and below 100'. Keep feet and knees together because you don't know where your feet will land. Bend knees slightly, and use them to cushion but not stop your descent altogether. You will be traveling 16 mph if properly suited. Tom Knauff recommends practicing getting out of the glider after landing with your parachute STILL ON. Most people release both the glider's seat belts as well as the parachute harness after landing so they can exit the glider. This reinforces the wrong technique for an emergency exit, when you should release only the glider harness. There apparently have been cases of people bailing out without their parachute fastened because of this bad practice. It is more difficult to exit the glider with your heavy chute still on, but it may save your life should a real emergency occur. Before climbing out of my glider first pull the normal canopy release, then imagine pulling the emergency release by touching the appropriate knob (the two releases are on opposite sides of a front hinged canopy in my case). Again, this reinforces what will be needed to do instinctively in a bail out emergency. |
