control forces if intentional maneuvers are necessary beyond ESP's
engagement threshold (i.e., isolated training maneuvers).
Take Off / Go Around Button
The remote TO/GA switch, located on the left side of the power lever,
selects the Takeoff or Go Around mode on the Flight Director. When
the aircraft is on the ground, pressing the TO/GA switch engages the
Flight Director command bars in Takeoff (TO) mode. When the aircraft
is in the air, pressing the TO/GA switch engages the Flight Director
command bars in Go Around (GA) mode and cancels all armed modes
except ALT ARM (ALTS).
• Note •
For aircraft without USP, selection of the TO/GA switch will
also disengage the autopilot.
For aircraft with USP, selection of TO/GA switch will not
change autopilot engagement (i.e., if initially engaged,
autopilot will remain engaged; if initially not engaged, autopilot
will remain not engaged).
After TO/GA engagement, other roll modes may be selected and
Autopilot engagement is allowed. However, an attempt to modify the
pitch attitude with the Pitch Wheel will result in a reversion to PIT
mode. Additionally, if in Approach mode, pressing the TO/GA switch
resumes automatic sequencing of waypoints by deactivating the
“SUSP” mode.
For aircraft with optional USP function, if power is insufficient to
maintain go-around attitude, the Autopilot will enter Underspeed
Protection Mode.
Pitch Trim Adapter
The Pitch Trim Adapter, located below the passenger seat, takes input
from the trim switches, Integrated Avionics Units, and the pitch servos
to allow the GFC 700 to drive the pitch trim cartridge.
28 VDC for Pitch Trim Adapter operation is supplied through the 2-amp
PITCH TRIM circuit breaker on Main Bus #1.
Electric Pitch/Roll-Trim Hat Switch
The yoke mounted Electric Pitch Trim and Roll Trim Hat Switch allows
the pilot to manually adjust aircraft trim when the Autopilot is not
engaged.
