Monitoring the Standby Nav channel
The Nav radio provides a monitor function for VORs as the standby channel similar to
the Com radio. The monitor function is activated or deactivated by pressing the NAV button
while in the Nav function. The From radial for the standby channel is shown in parentheses
when the VOR monitor mode is activated. This replaces the station identifier, OBS course, or
VOR/LOC indicator. A small “m” will replace the “s” in front of the Standby frequency. The
Standby VOR radial is updated once per second. You cannot monitor a Localizer channel.
111.80 m117.40 (267) from 115
If no signal can be tracked on the standby channel, then it will be dashed out.
111.80 m115.40 (---) from 115
The VOR Monitor function is turned off when you flip/flop frequencies, recall a frequency,
or press NAV again. Monitoring is not canceled by switching to Com.
Using the Standby Channel to Monitor a Second VOR
You can use the monitor function of the Standby channel as if it were a second Nav receiv-
er. This is useful to check for crossing points on the course you are navigating along. The two
following examples show how to monitor the second channel. You can use these examples to
develop your own solutions for other in-flight navigation needs.
