Tailslide

The male (English tail slide ) is a competition aerobatic figure from the Aresti catalog. The folding (see below) can be forward or backward, wherein the predetermined direction in the program must be maintained, otherwise the figure is valid. In the German -speaking world has for the two versions of the unofficial designation " male " ( fold it to the front) and " female " ( Fold back ) established. In English, the two variants " canopy up" and " canopy down", or referred to in the U.S. often " wheels up" and " wheels down" tail slide.

To initiate the figure, pulling the aircraft with the help of the elevator from the straight flight straight up. In the vertical position the aircraft is now getting slower until it stops and then falls back down backwards. This attitude, however, is unstable, so that the aircraft sooner or later Fold, ie to 180 ° will rotate about the transverse axis so that it returns to normal forward down flying, the direction of this turning up is determined using the elevator. For this vertical dive will be discharged back into the horizontal flight.

The difficulty of the figure is to be controlled in the specified direction turn over the plane, but without cheating before and already set out the direction in the upward movement. In the competition, the upward line but is usually not aware of exactly flown vertically to ensure the turning in the right direction, because the consequent deduction of points is always less bad than a completely invalid character. ( Turning in the wrong direction is considered to be a different figure and has in the evaluation therefore a "hard zero " result, which without this cheating may well also rounders happen, because the effect of the elevator is rather low in this situation. )

An absolutely perfect vertical backward slippage is not recommended for security reasons: because the more perfect the vertical, the longer the aircraft slips backwards before it turns. If the plane now but before turning over too much driving, so the forces of the slipstream on the rudder can be so great that the strength of the pilot is no longer sufficient to hold the rudder. These are then popped from the airstream with great force against the stops, what serious damage to the aircraft up to the total rudder failure may result. This may also happen in the elevator, even though it is held in the male to a stop when the aircraft turns at high speed in the wrong direction. This is because the main danger of this figure and the reason why it is expressly forbidden in many legal se for aerobatics aircraft.

The male may also be re- diverted in both attitudes from both the normal horizontal flight and from the inverted flight and initiated.
