amount will depend on the severity of the stall. If it stalls from a very nose
high attitude the stall will be quite pronounced and the nose will drop
through the horizon. If the entry was from a more shallow attitude the nose
may only drop slightly below the horizon.
The first action in the recovery is to release the back pressure. This usually
means put the stick forward to the neutral position. If you ever feel yourself
rising in the seat it means you have pushed the stick too far forward and
the nose has dropped further than it needs to and you will loose more
altitude than necessary during the recovery.
As soon as the nose drops the stall is effectively broken because the angle
of attack is now below the critical angle. However, you cannot yet pull back
on the stick to regain level flight. Push the throttle in full, let the speed build
to about 65 KIAS (120 km/h, 75 mph) and then smoothly pull back to level
flight. If you try to pull too soon and too vigorously you could induce a
secondary stall.
If the wing dropped at the stall point, resist the urge to pick it up with aileron
and use only rudder (left wing down, use right rudder and vice versa) to
level the wings. Because it is so natural to use aileron this is extremely
hard to do, even for experienced pilots, but it is a must to avoid inducing a
deeper stall on the lower wing. In fact, if you did everything wrong ie
pulling up without letting the speed build up, not getting the throttle to full,
and trying to lift the low wing with aileron, you probably will induce a spin.
On recovery with flaps extended ensure you do not exceed the maximum
speed with flaps extended (70 KIAS, 130 km/h, 81 mph)
If the stick is held fully back at the stall the aircraft will usually start to swing
laterally with increasing amplitude and possibly enter a deep stall which is
initially uncontrollable. If the air is smooth the swing may not occur and the
aircraft is fully controllable. Recovery in both cases is to simply release the
back pressure and let the speed build up when normal flight may be
regained.
