A parachute that has been repacked within the proceeding 120 days should be
worn by all of the pilots. Parachutes provide an alternative for surviving an
in-flight emergency where the aircraft is uncontrollable. They are effective
only if the parachute is serviceable, correctly fitted, and operated
correctly. Accordingly, before wearing a parachute you must be familiar with
inspection of parachutes, correct fitting of parachutes, and proper operation
of them, including exiting the glider prior to use.
