AUTOMATIC FLIGHT CONTROL SYSTEM
Vertical GA mode generates a fixed pitch attitude of 10°, based on power being
developed by the engines.
The autothrottle will provide full takeoff thrust until GA mode is cleared.
GA mode can be cleared by selecting the AP on (PIT), or by selecting another vertical
mode.
WINDSHEAR GUIDANCE (WSHR) MODE
Windshear provides for detection of windshear conditions and escape guidance during
approach and takeoff phases of flight.
WSHR mode can be activated by either depressing the throttle-mounted TOGA
button, or advancing the thrust levers towards takeoff, when a windshear warning has
been displayed on EFIS.
WSHR mode will provide vertical guidance in accordance with optimal windshear
escape profile. The airplane will not be commanded to descend unless the airplane is
encroaching on the stall speed safety margin.
Lateral guidance will maintain wings level.
For an increasing performance shear (updraft/headwind), an amber “WINDSHEAR”
caution message will be displayed on the PFD. The WSHR guidance mode cannot be
activated when the caution message is displayed.
