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, turn the bottom right 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 knob to nominate that
frequency into the standby slot for swapping.†
NOTE
Nearest Lists Capped at 100nm
Most Nearest lists will only display entries that are
within 100nm of the current aircraft position.
ARTCCs use 200nm.
