Parachute

Wearing parachutes for aerobatics flying is regulated in FAR 91.307. It specifies that whenever you carry a passenger, you may not exceed 60 degrees of bank or 30 degrees of pitch up or pitch down unless both occupants wear an approved parachute. This means that you do not have to wear a parachute when you fly alone. It does not say anything about aerobatics, it just specifies the bank and pitch limits.
So any maneuver that exceeds these limits falls under this rule and requires you and your passenger to wear a parachute.
The parachute I use are National model 490.
This is a very light parachute (12.8 lb) but at the same time is a strong parachute.
Easy and confortable to wear, and is inspected every 120 days for safety and according to the current regulations.
