Aerobatic box

This is an aerobatic box layout on the ground. It marks the borders of the performance zone.
The size is 1000 x 1000 meters (3300' x 3300').

I make the strips much bigger in flight simulator since the original size doesn't help a lot.
The arrows on the main axis are displaying the wind direction. This is important that you know the direction to start your performance.

The Judges will be on one side of the secondary axis.

You will fly your program parallel to the main axis - in the case of cross-box figures, you will fly parallel to the secondary axis. The more you are pointing in the wrong direction the lower the grade would be.

Of course, the real box is not on the ground but in the air. There are lower and upper boundaries depending on the class you are flying in:

-> Advanced and Unlimited defined by FAI in meters.
-> In brackets the values are displayed from the IAC-Homepage.
-> Values from Sportsman and Intermediate are German specifics.
-> Disqualification height is always half of the lower border.

Boundary		Sportsman	Intermediate	Advanced	Unlimited
upper border		1100 m (3500') AGL *	1100 m (3500') AGL	1100 m (3500') AGL	1000 m (3280') AGL
lower border		400 m (1500') AGL	300 m (1200') AGL	200 m (800') AGL	100 m (328') AGL
disqualification		200 m AGL	150 m AGL	100 m AGL	50 m AGL

* There are no penalty points if exceeding the upper border in the sportsman, intermediate and advanced class. Nevertheless there will be reduction on the framing mark.

For our competition I will ALWAYS go for the meters displayed here in this table. If you attend a local competition please ask the officials before you start the competition.
