• Airplane maneuver area is clear of cloud and turbulence; and
• Yaw damper is on.
(1) STALL CHARACTERISTICS
There is no natural stall warning or aerodynamic buffet prior to the stall in the altitude
range of between 13,000 feet and 15,000 feet. As a high angle of attack approaches,
continuous ignition is activated. Stall warning is provided by a stick shaker, which is set to
operate at varying percentages of indicated airspeed above the stalling speed. Stick
shaker speeds are presented in tabular form in Figure 07−05A−1 to Figure 07−05A−4.
The stall is defined by the operation of the stick pusher and the associated nose down
attitude change. Alternate stall identification are provided by the STALL switch/lights on
the glareshield panel flashing red and the warbler coming on. Stick pusher speeds are
presented in tabular form in Figure 07−05A−5 to Figure 07−05A−8.
(2) ENTRY AND RECOVERY PROCEDURES
Start the maneuver by establishing the appropriate configuration with the thrust levers set
to IDLE. Trim the airplane at an airspeed of approximately 1.4 VS in that configuration
after setting the required power. Reduce the airspeed by pitching the nose up (with the
wings kept level) at a deceleration rate of not more than one knot per second. Rapid or
violent movements of any flight controls during the approach to the stall should be
avoided, particularly at airspeeds below the operation of the stick shaker. Any tendency to
yaw during the approach to the stall should be corrected by normal use of the rudder.
Immediately after the stall is recognized, prompt and positive recovery action should be
taken by forward movement of the control column and simultaneous addition of power.
This nose down attitude should be maintained and power added until airspeed is
increased sufficiently to accomplish a smooth pull out. At no time should speed be
allowed to reduce to more than 2 knots below the stick pusher speed.

(3) STICK SHAKER AND STICK PUSHER SPEEDS
The indicated stick shaker and stick pusher speeds for varying airplane weights and
pressure altitude are presented in the following tables:
Figure 07−05A−1 provides the stick shaker speeds for flaps 0° and gear up;
Figure 07−05A−2 provides the stick shaker speeds for flaps 20° and gear up;
Figure 07−05A−3 provides the stick shaker speeds for flaps 30° and gear up;
Figure 07−05A−4 provides the stick shaker speeds for flaps 45° and gear down;
Figure 07−05A−5 provides the stick pusher speeds for flaps 0° and gear up;
Figure 07−05A−6 provides the stick pusher speeds for flaps 20° and gear up;
Figure 07−05A−7 provides the stick pusher speeds for flaps 30° and gear up; and
Figure 07−05A−8 provides the stick pusher speeds for flaps 45° and gear down.
The stick shaker and stick pusher speeds were calculated based on a reference centre of
gravity (CG) position of 20% MAC. To estimate stick shaker and stick pusher speeds at a
different CG position, reduce the speeds derived from the following tables by 0.1% for
every 1.0% MAC aft of the reference CG position.
Example:
Associated Conditions:
Airplane weight = 38,000 lb
Altitude = 14,000 ft
Flaps = 20°C
Landing gear = Up
CG = 21% MAC
Using Figure 07−05A−2, the estimated stick shaker speed for the above conditions is
calculated as follows: 134.5 − (134.5 X .001) = 134.4 KIAS
Using Figure 07−05A−6, the estimated stick pusher speed for the above conditions is
calculated as follows: 126.0 − (126.0 X .001) = 125.9 KIAS
