Recovery from a Fully Developed Stall
777-200 - 777-300ER
An airplane may be stalled in any attitude (nose high, nose low, high angle of
bank) or any airspeed (turning, accelerated stall). It is not always intuitively
obvious that the airplane is stalled.
An airplane stall is characterized by any one (or a combination) of the following
conditions:
• buffeting, which could be heavy
• lack of pitch authority
• lack of roll control
• inability to arrest descent rate.
These conditions are usually accompanied by a continuous stall warning. A stall
must not be confused with the stall warning that alerts the pilot to an approaching
stall. Recovery from an approach to a stall is not the same as recovery from an
actual stall. An approach to a stall is a controlled flight maneuver; a stall is an
out-of-control, but recoverable, condition.
Note: Anytime the airplane enters a fully developed stall, the autopilot and
autothrottle should be disconnected.
To recover from a stall, angle of attack must be reduced below the stalling angle.
Nose down pitch control must be applied and maintained until the wings are
unstalled. Application of forward control column (as much as full forward may be
required) should provide sufficient elevator control to produce a nose-down pitch
rate.
Under certain conditions, on airplanes with underwing-mounted engines, it may
be necessary to reduce thrust in order to prevent the angle of attack from
continuing to increase. Once the wing is unstalled, upset recovery actions may be
taken and thrust reapplied as needed.
If normal pitch control inputs do not stop an increasing pitch rate in a nose high
situation, rolling the airplane to a bank angle that starts the nose down may be
effective. Bank angles of about 45°, up to a maximum of 60°, could be needed.
Normal roll controls - up to full deflection of ailerons and spoilers - may be used.
Unloading the wing by maintaining continuous nose-down elevator pressure
keeps the wing angle of attack as low as possible, making the normal roll controls
as effective as possible.
Finally, if normal pitch control then roll control is ineffective, careful rudder input
in the direction of the desired roll may be required to initiate a rolling maneuver
recovery.
