Aerobatics Briefing For BGA Standard Aerobatics Badge

The Law n Aerobatics are prohibited over congested or urban areas or within controlled airspace without the consent of the appropriate air traffic control unit.

BGA Recommended Practices n RP 18. The CFI should lay down minimum heights for aerobatics at his club and no aerobatics should be done below this height without special permission.

BGA Recommended Practices n RP 19. The CFI is responsible for the authorisation of all aerobatic flights carried out from the club site in either club or privately owned gliders. Before authorising a flight in which advanced aerobatics, including rolling and inverted manoeuvres, are to be carried out, the CFI should ensure that the flight has been authorised by a BGA approved Aerobatics Instructor. The authorisation should be in writing if the Aerobatics Instructor is not present at the time of the flight and should specify minimum heights for the manoeuvres intended and should also specify weather minima and recency requirements for the manoeuvres to be carried out.

BGA Recommended Practices n RP 20. Any pilot exceeding the ‘g’ loading permitted by the glider’s Flight Manual should report this and the aircraft should not be flown again until it has been inspected and a log book entry made and signed by an approved inspector. Damage incurred by one pilot may result in structural failure when the aircraft is being flown by another pilot.

BGA Recommended Practices n Aerobatics Training in full aerobatics, involving sustained inverted flying and rolling, may be given only on a dual-control twoseater by an instructor holding an Aerobatics Instructor Rating. All gliders used for aerobatics training (excluding spinning) must be fitted with a serviceable accelerometer, visible to the instructor

Badge Tests n n The candidate must have received clearance from a BGA Aerobatic Instructor to carry out the figures included at the relevant level before attempting any test. For the Standard badge this clearance may be given by a Full Cat. Instructor authorised for the purpose by the local CFI. The candidate must be alone in the aircraft for each test. The Standard badge test may be witnessed by any BGA Aerobatic Instructor or by a Full Cat. Instructor authorised for the purpose by the local CFI. More than one test may be completed on a single flight.
