3. B. (2) (k) VOR Track
VOR track will occur as the aircraft is established on beam
center and the following conditions are all satisfied:
● The VOR mode has been captured or AOSS 2 has occurred.
. Thirty seconds of
● Lateral deviation

elapsed time from capture.
rate is less than 50 feet per second and
angle is less than 6 degrees.
At this time course error is eliminated from the command
signal, leaving beam deviation and lateral acceleration from
the IRS
to maintain the aircraft on beam center. There is no
visual indication in the cockpit that the VOR track submode has
occurred.
(1) LOC CAP 1 and BC
CAP 1
Localizer and back course capture 1 are the initial capture
phases of their respective modes. Localizer capture 1 and back
course capture
1 will occur when the following conditions are
all satisfied:
● LOC armed plus 3 seconds.
. Either of the following occurs:
- Lateral beam sensor trips.
- Beam deviation less than 35 mV.
(m) LOC CAP 2 and BC CAP 2
Local izer and back course capture 2 are capture phases which
indicate the aircraft is now flying closer to the center of the
beam.
The capture 2 phase will
occur for each mode when the
following conditions are all satisfied:
. LOC CAP 1 plus 3 seconds.
. Course error less than 35 degrees.
. Beam deviation less than 175mV (165 mV -906/907 FGC).
