BENDIXKing AeroNav 910 Pilot's Manual page 149

Each Nearest type list can be scrolled either via touch (use a
vertical swipe of the finger) or via the bottom right AeroNav knob.
If the highlighted item is an airport, pressing the Direct-To
function key on the bezel will display the Direct-To green dialog
box with the highlighted airport pre-populated as the Direct-To
location.
Pressing the NRST function key will bring up the Nearest tab in
the split Map-Nearest view. Each subsequent push of the "NRST"
function key will step to the next nearest data type.
If the Nearest page is left for 60 seconds or more and then is
returned to, the Nearest Airports selection will be the active
nearest data type no matter what the last nearest data type may
have been. For example, if the Nearest VORs selection was the
most recent display of nearest data, and then the pilot selects a
map page for more than 60 seconds, when the Nearest tab is
next selected, Nearest Airports data is now displayed and not
Nearest VORs.
TIPS AND TECHNIQUES
Emergency Return to Departure Airfield
If on departure leg and an emergency return to the
departure airfield is deemed necessary, the
recommended technique is to press the –D-> button
on the bezel, twist the bottom right AeroNav knob
counter-clockwise to pre-fill the departure airfield
and press ENTR, ENTR to make that the active
waypoint. Then press the PROC key to produce a
dropdown list of approaches and select the desired
one. To quickly get the tower frequency of that
airfield, press the NRST button on the bezel and
confirm the departure airfield is the highlighted row.
You can then press the bottom right AeroNav knob
to nominate that frequency into the #1 standby slot
for swapping.†
