With closed air brakes, a stall warning occurs as a light buffeting
and vibration and oscillation of the ASI needle towards the stalling
speed.
If the air brakes are extended, the airframe vibrates noticeably at
approx. 5km/h (2 kts, 3mph) above the stalling speed.
If the air brakes are extended, the loss of altitude after wing drop is
approx. 50m (150 ft).
