RIGHT-HAND KEYS AND KNOBS
The RNG Key allows the pilot to select the desired map
range. Use the up arrow of the key to zoom out to a larger
area, or the down arrow to zoom in to a smaller area.
The Direct-to Key provides access to the direct-to
function, which allows the pilot to enter a destination
waypoint and establishes a direct course to the selected
destination.
The MENU Key displays a context-sensitive list of
options. This options list allows the pilot to access
additional features or make settings changes which relate
to the currently displayed page.
The CLR Key is used to erase information, remove
map detail, or to cancel an entry. Press and hold the CLR
key to immediately display the Default NAV Page.
The ENT Key is used to approve an operation or
complete data entry. It is also used to confirm information,
such as during power on.
The large right knob is used to select between the
various page groups: NAV, WPT, AUX, or NRST. With
the on-screen cursor enabled, the large right knob allows
the pilot to move the cursor about the page. The large
right knob is also used to move the target pointer right
(turn clockwise) or left (counterclockwise) when the map
panning function is active.
The small right knob is used to select between the
various pages within one of the groups listed above. Press
this knob momentarily to display the on-screen cursor.
The cursor allows the pilot to enter data and/or make a
selection from a list of options. The small right knob is
also used to move the target pointer up (turn clockwise) or
down (counterclockwise) when the map panning function
is active.
BOTTOM ROW KEYS
The CDI Key is used to toggle which navigation source
(GPS or VLOC) provides output to an external HSI or CDI.
The OBS Key is used to select manual or automatic
sequencing of waypoints. Pressing the OBS Key selects
OBS mode, which retains the current 'active to' waypoint
as the navigation reference even after passing the waypoint
(i.e., prevents sequencing to the next waypoint). Pressing
the OBS Key again returns the unit to normal operation,
with automatic sequencing of waypoints. When OBS
mode is selected, the pilot may set the desired course to/
from a waypoint using the 'Select OBS Course' pop-up
window, or an external OBS selector on the HSI or CDI.
The MSG Key is used to view system messages and to
alert the pilot to important warnings and requirements.
The FPL Key allows the pilot 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 FPL Key.
The PROC Key allows the pilot to select and remove
approaches, departures, and arrivals from the flight plan.
When using a flight plan, available procedures for the
departure and/or arrival airport are offered automatically.
Otherwise, the pilot may select the desired airport, then
the desired procedure.
