Many people who flew with me had no idea that we had a parachute for some sort of emergency. How it works? They are two people and only a paraqueda, this goes with the instructor. The parachute is just one, but it's big enough for both people. The parachute is used if the delta wing accidentally breaks, so the instructor launches the parachute that brings the pilot, the student and the delta wing to the ground. For everything to work when needed, it is important that the parachute be folded every 6 months at least to remove the static that is generated with the closed parachute.
