Crash detection #568

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Feature that you'd like us to add or change you'd like us to make:

If during flight there is more than 8 G acceleration to any direction, that 
must be a crash, and Arduplane should stop motor immediately (but still try to 
fly as well as possible)

If plane hits to tree or ground, the speed goes to zero. Arduplane tries to 
maintain speed, and put more and more power. Prop will crash, and probably also 
motor and motor controller will burn.

In normal flight there should not be big G values. In crashes I have seen even 
20 G. During catapult launch there can be also big values, but crash detection 
should happen only more than one second after the launch. The limit 8 G is one 
good guess...

If plane hits to tree top, but does not stuck to tree, motor should stop, but 
the plane should still try to fly without motor.
