why dont they use air brakes?[/quote:70fc5]

Air brakes are nothing to do with an emergiencies. There designed break the airflow over the wing, causing the plane to lose alot of height (i.e. when on final)

I dont understand what u mean by using airbrakes when a plane crashes

Smaller aircraft have the pilot/co pilots strapped in pernamently, as their more likely to make steeper turns, causing the pilots to be sliding around in their seats (sorta like when driving a car. The belts help secure you to the centre of the seat (simular to bucket seats in a car).

AS others have said there used on airliners when facing large turbulance.
