ARMED VS ENGAGED/ACTIVE INDICATIONS

The active AeroNav nav mode is displayed in the upper right
corner of the display. If there is an "armed" AeroNav nav mode, it
will be displayed in cyan, to the right of the active mode,
preceded by an arrow. The illustration below shows the system
in GPS mode, with VLOC armed.
Nav Source Mode Armed and Engaged Depiction
As the armed mode is captured, the previously active nav mode
will be removed and the previously armed state will turn green
and begin to flash. The mode will flash for approximately five
seconds and then turn green. When the green indication stops
flashing, the AeroNav will be in the new nav mode.
To trigger the transition from armed VLOC to active VLOC, all of
the following capture criteria must be met:

The tuned frequency in the nav radio matches that of the
approach navaid

The Morse code decoded by the tuned nav radio
matches the identifier of the approach navaid

The aircraft track is within 15° of the final approach
course

The course to the active waypoint is within 45° of the final
approach course

The radio deviations are at most 50% of full scale for 5
consecutive seconds

The active leg is part of the approach up to and including
the final approach fix
