Bottom Row Keys
N
The NRST key displays the Nearest Airports page. Then, rotating the small
right knob steps through the NRST pages.
The OBS key is used to select manual or automatic sequencing of waypoints.
O
Pressing this key selects OBS mode, which will retain the current "active to"
waypoint as your navigation reference even after passing the waypoint (i.e.,
prevents sequencing to the next waypoint). Pressing the OBS key again will
return to normal operation, with automatic sequencing of waypoints. Whenever
OBS mode is selected, you may set the desired course to/from a waypoint using
the OBS Page, or an external OBS selector on your HSI or CDI.
M
The message key is used to view system messages and to alert you to
important warnings and requirements.
F
The flight plan key allows you to create, edit, activate and invert flight plans,
as well as access approaches, departures and arrivals. A closest point to flight
plan feature is also available from the flight plan key.
The vertical navigation key allows you to create a three-dimensional
VNAV
profile which guides you to a final (target) altitude at a specified location.
P
The procedures key allows you to select approaches, departures and arrivals
from your flight plan. When using a flight plan, available procedures for your
departure and/or arrival airport are offered automatically. Otherwise, you may
select the desired airport, then the desired procedure.
