red GEAR UNSAFE alert will be displayed if the landing gear is in transition (neither fully up nor
fully down).
• Gear Up (Amphib) - Same as the preceding Gear Up configuration, except it also displays a blue
GEAR UP message on the PFD when the gear is confirmed up. This is intended for use in
amphibious aircraft that desire a positive indication of both gear-up and gear-down states.
• Stall Switch - When the input is active, a red flashing STALL message appears on the PFD and a
warning tone sounds continuously. (Audible stall warning tones are inhibited when the aircraft is
on the ground.)
• Squat Switch - Used with a weight-on-wheels switch that activates the input when the aircraft is on
the ground. If a Stall Switch input is also configured, the Squat Switch input will override it (to
reduce nuisance alerting when the stall switch is activated while the aircraft is on the ground). The
Squat Switch input is also used as an additional factor for determining airborne/on-ground status.
• Speed Brake - Used with a switch that activates the input when the aircraft's speed brake is fully
retracted (closed). A white SPEED BRAKE message will appear on the PFD if the Speed Brake
discrete input is not active. If engine power is increased, such as if the speed brake is deployed
during takeoff or climb, the SPEED BRAKE message will flash red and a tone will sound. If the
aircraft has a maximum airspeed limit for speed brake deployment, it can be configured as a
custom reference speed with the label "VSB" (see
setting, if the Speed Brake input is not active and the aircraft's indicated airspeed exceeds VSB, the
SPEED BRAKE message will flash red and a tone will sound.
• AFCS Level - Used in conjunction with the autopilot to activate LVL mode. This input should be
connected to a momentary pushbutton.
• AFCS TO/GA - Used in conjunction with the automatic flight control system (AFCS) flight
director to activate Takeoff or Go-Around mode. This input should be connected to a momentary
pushbutton located near the pilot's throttle control.
• ESP Inhibit - Used with a switch that activates the input. When in the active state (select active
high or active low), the ESP (Electronic Stability and Protection) function is disabled. See
Section 33.4.8 for ESP configuration details.
• Pitot Temp - Will display a PITOT TEMP caution message on the PFD if the outside air
temperature is below approximately 7°C (45°F) and the input is not active. Configure for Active
Low when used with the regulated GAP 26 (-20 version). See also
