In general, thislow speed can be brought down to the angle of incidence where the LiftcoeflScient attains its maximum value. But if we go beyond this theair support for flight ceases, the power of the controls is lost and theaeroplane sinks in a haphazard manner, very expressively called a the aeroplane lands flat, in this way, without support, it is saidto perform a pancake. As a matter of fact an aeroplane can be made to stall at anyangle of incidence if the power is cut down low enough. But the stallwill gradually build up to the same maximum lift angle before loss ofcontrol occurs.
