Technique For Stalls
The stalling technique is as follows:
1. All stalls are to be made in straight (wings level) flight.
2. Stalls with flaps retracted and in the take-off configuration should be carried out at idle thrust. To
reduce altitude loss with approach or landing flaps, thrust should be adjusted not to exceed 77% N
1
.
Once thrust is set it should not be reduced during the approach to the stall and recovery.
3. The airplane should be trimmed at an airspeed of approximately 1.4 V
S1
in the appropriate
configuration after setting the required thrust.
4. The airspeed should be reduced at not more than one knot per second. Rapid or violent movements
of any control during the approach to the stall should be avoided, particularly at air speeds below
the operation of the stick shaker.
With the yaw damper off, any tendency to yaw during the approach to the stall should be corrected
by normal use of the rudder.
5. The stall is identified by a short forward movement of the control column provided by the Stall
Identification System. The red STALL VLV OPEN annunciators will illuminate. The airplane should
be allowed to pitch nose down until the stick push has cancelled, and should then be recovered to
normal controlled flight. Any tendency to roll should be corrected by use of ailerons.
Do not attempt to hold the airplane in the stall.
Stall Characteristics
CAUTION: A FREQUENT REASON FOR UNACCEPTABLE STALL CHARACTERISTICS IS A
TENDENCY TO ROLL AT THE STALL. IT IS ACCEPTABLE FOR A MODERATE
ROLL TO OCCUR, PROVIDED THAT NORMAL USE OF AILERONS CAN LIMIT THE
ROLL ANGLE TO NO MORE THAN 20°.
AILERON SNATCH MAY OCCUR AT OR PRIOR TO STALL AND IS NOT
ACCEPTABLE. THE AILERON SNATCH MAY BE STRONG ENOUGH TO AFFECT
RECOVERY USING AILERON INPUT, IN WHICH CASE THE ELEVATOR CONTROL
MUST BE MOVED FORWARD TO DECREASE THE ANGLE OF ATTACK AND
ALLOW THE RETURN OF NORMAL AILERON CONTROL. IN SUCH AN EVENT THE
PILOT MUST BE PREPARED TO RECOVER FROM AN UNUSUAL ATTITUDE.
PILOTS CONDUCTING STALL CHECKS SHOULD HAVE PRIOR EXPERIENCE IN
PERFORMING STALLS IN THE HAWKER AND MUST BE PREPARED FOR
UNACCEPTABLE STALL BEHAVIOR AT ANY POINT LEADING UP TO AND
THROUGHOUT THE MANEUVER.
There is no natural stall warning or aerodynamic buffet prior to the stall. Stall warning is provided by a
stick shaker which is set to operate at an indicated airspeed of 7% to 9% above the stalling speed.
