AFMS N°D01 FOR GARMIN GFC700 AUTOPILOT INSTALLATION AND
RNAV/RNP NAVIGATION ELIGIBILITY
Section 4 – Normal procedures
AUTOPILOT MODES
ALTITUDE HOLD MODE (ALT)
Turning the ALT knob while in Altitude Hold Mode changes the Selected
Altitude, but not the FD Altitude Refrence, and does not cancel the
mode.
FLC MODE
The Selected Altitude MUST be set before selecting Flight Level
Change Mode.FLC IAS selection is directly linked to actual IAS, pi-
lot will need to monitor airspeed after selection of FLC mode.
VERTICAL NAVIGATION MODES (VPTH, ALTV)
VNV is disabled when parallel or dead reckoning mode is active.
The selected altitude takes precedence over any other vertical con-
straints.
If another pitch mode key is pressed while Vertical Path Tracking Mode
is selected, VPTH mode reverts to armed.
If the selected altitude is not at least 75 ft below the VNV Target Alti-
tude, the FD captures the Selected Altitude once Vertical Path Tracking
Mode become active (ALTS is armed rather than ALTV).
Altitude preselect must show an altitude below the flight plan’s Target
Altitude.
If the selected altitude is not at least 75 ft below the VNV Target Alti-
tude, the FD captures the Selected Altitude once Vertical Path Tracking
Mode become active (ALTS is armed rather than ALTV).
If VPTH is armed more than 5 minutes prior to descent path capture,
acknowledgement is required for the FD to transition from Altitude
Hold to VPTH.
To proceed with descent path capture if the white “VPTH” flashes,do
the following:
- Press VNV Kay
- Turn ALT knob to adjust the Selected Altitude.
If the selected altitude is not at least 75 ft below the VNV Target Alti-
tude, the FD captures the Selected Altitude once Vertical Path Tracking
Mode become active (ALTS is armed rather than ALTV).
Armed VNV Target Altitude and Selected Altitude capture modes are
mutually exclusive. Selected Altitude Capture Mode is armed also (not
annunciated) whenever VNV Target Altitude Capture Mode is armed.
APPROACH MODES
The selected navigation receiver must have a valid VOR or LOC signal
or active GPS course for the flight director to enter Approach Mode.
