POM DESCRIPTION
Stall Warning and Protection
The Stall Warning and Protection System (SWPS) include a stick shaker
and a stick pusher, as well as visual indications and aural alerts. The stall
warning and protection system is primarily driven from the air data probe
angle of attack (AoA) data.
The stall protection function of the system incorporates a tactile (shaker)
alert and a stick pusher actuated by the pitch servo. The pusher moves
the elevator in the nose down direction to immediately decrease the AoA.
An aural "STALL, STALL" alert and a red STALL PFD flag will
annunciate in the stalled condition if recovery has not occurred within
expected time.
In addition to the stall warning and protection, the airspeed indicator
incorporates a complementary function in the Low Speed Awareness
(LSA) cue. The LSA appears as a colored bar at the bottom of the
airspeed tape. The top of the red and white "barber pole" indicates stall
warning (stick shaker). Below this, the top of the solid red bar represents
stall protection (stick pusher).
When ice is detected or the wing anti-ice is operated manually, the stall
warning and protection system automatically compensates after a delay
of sixty (60) seconds. This compensation has two schedules, one for
normal operation of the icing protection systems and one for failure
modes. When the system is operating in either schedule, the STALL
WARN ICE ADVANCE advisory message is displayed, as is a
STALL WARN ICE ADVANCE message on the ICE PROTECTION
synoptic page.
