- Use of autothrottle
General
The Autothrottle (AT) function is fully integrated with the Automatic Flight Control
System (AFCS) and is associated with the Single Engine Indicator (SEI). AT
automatically actuates the THROTTLE lever to control engine power within
operational limits, in order to reach and maintain the manually selected airspeed
(MAN mode) or programmed flight phase schedule (FMS mode).
●
NOTE
●
If needed, autothrottle stability and damping can be improved by increasing the
friction on the THROTTLE lever using the thumbwheel located on right side of
the pedestal console - see Figure 7.6.2.
●
For more information on AT modes and cockpit controls, refer to GARMIN Pilot’s
Guide, Autothrottle section.
For more information on SEI, refer to section 7.6 Powerplant, Single engine indicator
and to GARMIN Pilot’s Guide, Engine Indication System (EIS) section.
AT engine and airspeed protections
The AT function includes engine and airspeed protections to enhance flight safety. AT
engine and airspeed protections automatically activate if necessary, both when the
AT is engaged and when the AT is disengaged.
AT engine and airspeed protections are automatically inhibited below 400 ft AGL.
The default setting for the AT engine and airspeed protections is ON at avionics power
up. The ESP system and the AT engine protection system must remain ON for all
normal operations. If necessary, for a specific training maneuver or maintenance
check, these systems can be temporarily turned off with the Stability & Protection
button in the avionics setting of the GTC menu. The
ESP OFF
advisory CAS
message indicates that the AT engine protection system and the ESP system
protections are OFF. Following completion of the training maneuver or maintenance
check turn ESP on.
