CS 22.255 Aerobatic manoeuvres ED Decision 2003/13/RM (a) Each Aerobatic and Utility Category sailplane must be able to perform safely the aerobatic manoeuvres for which certification is requested. (b) It must be shown that aerobatic manoeuvres can be carried out with adequate margins between the speeds and accelerations attained therein and the proof strength and design speed of the sailplane. (c) When determining the flight characteristics, account must be taken of the possibility of exceeding the recommended entry speeds for the manoeuvres and errors which are likely to be made by the pilot while being trained for aerobatic manoeuvres. (d) During the flight tests it is not permitted to use any means (e.g. air brakes, wing-flaps) to restrict the speed in aerobatic manoeuvres. (e) The recommended entry speed and where appropriate, the maximum acceleration must be determined for each manoeuvre approved.
