FLIGHT LEVEL CHANGE (FLC) MODE:
1. Altitude Preselect ....................................................................................SET to Desired Altitude
2. Press FLC Button ......................................... GREEN ‘FLC’, White ‘ALTS’ annunciated on PFD
3. AIRSPEED Reference ................................................................ ADJUST using UP / DN Wheel
4. Green ‘ALT; .................................................................... VERIFY UPON ALTITUDE CAPTURE
NOTE
If the altitude preselect is not changed before selecting FLC, the autopilot may re-capture
the current altitude immediately after entering FLC mode. Always ensure that the altitude
preselect is adjusted prior to selecting FLC.
Pressing the SPD button while in FLC Mode toggles the airspeed reference between
KIAS and Mach. FLC will automatically transition from Mach to KIAS reference during a
descent when the current Mach reference equals 220 KIAS. FLC will not automatically
transition from KIAS to a Mach reference during a climb.
ALTITUDE HOLD (ALT) MODE, MANUAL CAPTURE:
1. At the desired altitude ................................................... PRESS ALT Button on Mode Controller
2. Green ‘ALT’ ........................................................................................................ VERIFY on PFD
If climbing or descending, the aircraft will overshoot the reference altitude and then return
to it. The amount of overshoot will depend on the vertical speed when the ALT button is
pressed.
VERTICAL NAVIGATION (VNAV)
VNAV Descent
Vertical navigation will only function when the navigation source is GPS navigation. VNAV will
not function if the navigation source is VOR, Localizer, or ADF. The airplane’s heading must
be within 75
°
of the desired GPS course and within 10 NM cross track error in order of VNAV
to function.
VNAV functions only for enroute and terminal descents. Vertical navigation is not available
during climbs or descents between the final approach fix (FAF) and the missed approach
point (MAP). Refer to the G1000 Cockpit Reference Guide and Pilot’s Guide for additional
information.
1. Once clearance from ATC has been received ................................... RESET Altitude Preselect
to the vertical clearance limit.
2. VNV Button .............................................. PRESS within 5 minutes of the top of descent (TOD)
