VHF COM
The pilot uses the menu to select the KSN 770 transceiver VHF channel
spacing as either 25 kHz or 8.33 kHz.
The VHF COM operating range is 118.000 MHz to 136.990 MHz.
VHF NAV
The VHF NAV operating range is 108.00 MHz to 117.95 MHz.
NAV Radio Autotune
If configured, the KSN 770 will autotune the NAV radios for ILS and
localizer approaches only. When an ILS or localizer approach is
inserted into the flight plan, the standby NAV frequency is tuned to the
ILS or localizer frequency.
The standby NAV frequency is automatically set to the active NAV
frequency when all of the following conditions are met:
D
The final approach waypoint (FAWP) has not been sequenced
D
An ILS/LOC approach procedure is active in the flight plan
D
Track is within 35 degrees of the inbound track as defined from the
FAWP to the missed approach waypoint (MAWP).
