WINDSHEAR ESCAPE GUIDANCE MODE
The Windshear Escape Guidance mode is used to minimize altitude
and speed loss during a windshear encounter. The strategy is to keep
the airplane airborne until the windshear conditions subside or are
exited.
The Windshear Escape Guidance Mode provides pitch command to
recover from a windshear encounter. The amplitude of the pitch
command will depend upon the airplane’s performance and windshear
severity and phase.
The Windshear Escape Guidance is a Flight Director mode engaged
under the following conditions:
−
Manually, by pressing the Go Around Button while a windshear
condition (increasing/decreasing performance) is detected;
−
Automatically, when in Go Around or Takeoff Mode and a windshear
condition (increasing/decreasing performance) is detected;
−
Automatically, when Thrust Levers Angle is above 78° and a
decreasing performance windshear is detected (windshear warning).
When the windshear escape guidance mode is engaged a green
“WSHR” indication is displayed on both PFDs in the Vertical Mode
field and a “ROLL” indication is displayed in the Lateral Mode field.
Whenever the Windshear Escape Guidance mode is engaged, the
Pitch Limit Indicator (PLI) symbol is drawn directly on the Attitude
Display Indicator portion of the PFD. The PLI represents the remaining
angle of attack margin before Stick Shaker triggering.
All other Flight Director modes are canceled and the following vertical
modes are inhibited when a caution or warning windshear condition is
presented:
−
Altitude Preselect Mode, Go Around and Takeoff.
No lateral modes are inhibited while in the vertical mode of WSHR.
The Windshear Escape Guidance mode is designed to meet the
following requirements, in the listed order of priorities:
−
Prevent the airplane from stalling;
−
Prevent the airplane from descending;
−
Prevent the airplane from exceeding V
MO
