The capture point is variable and depends on intercept angle and closure rate.
Localizer capture occurs not later than 1/2 dot deviation. Course capture is
indicated when VOR/LOC annunciation changes from armed to engaged.
While engaged in VOR or LOC modes:
• A autopilot and Captain’s F/D use information from Captain’s course
selector and No. 1 VHF NAV receiver
• B autopilot and First Officer’s F/D use information from First Officer’s
course selector and No. 2 VHF NAV receiver
• different courses and/or frequencies for two VHF NAV receivers can
cause disagreement between the Captain’s and First Officer’s F/D
displays and affect A/P operation.
Note:
When a localizer frequency is selected, VHF NAV radios automatically
switch from tail antenna to nose antenna when VOR/LOC is annunciated
(armed or engaged). If antenna switching does not occur, LOC mode is
inhibited.
Note:
Localizer backcourse tracking is not available.
