AUTOMATIC FLIGHT CONTROL SYSTEM
2-40
For Training Purposes Only
Sept 04
For a decreasing performance shear (downdraft/tailwind), a red “WINDSHEAR”
warning message will be displayed on the PFD. When WSHR mode is active, the
flight director lateral and vertical modes will be deactivated and replaced by the
“ROL” lateral mode and the “WSHR” vertical mode. The WSHR guidance mode will
be accompanied by an aural warning and will automatically disconnect the autopilot.
WSHR mode cannot be canceled when a Windshear Warning is present.
When the WSHR mode is activated, the attitude at which the aircraft will reach stall
speed is indicated on both PFDs by the Pitch Limit Indicator (PLI). The PLI is
removed from each PFD when the WSHR FD mode is disengaged.
NOTE
Windshear mode is currently disabled via an IAC configuration
module strap. Demonstration to FAA, Transport Canada and
JAA need to occur prior to certification.
