5-11 Navigation

ARMED VS ENGAGED/ACTIVE INDICATIONS

The active IFD nav mode is displayed in green along the right

edge of the top data strip. The armed IFD nav mode, if there is

one, is displayed in blue along that same top strip. When there is

an armed state, the nav source is depicted per the image below.

Nav Source Mode Armed and Engaged Depiction

As the armed mode is captured, the previously active nav mode

lamp will extinguish and the previously armed state will turn green

and begin to flash. The flashing should last approximately 5

seconds and the nav mode will not actually change until the

flashing stops and the indication becomes a solid lamp.

To trigger the transition from armed to active, 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 degrees of the final

approach course;

The course to the active waypoint is within 45

degrees 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.
