• glideslope capture occurs at 2/5 dot below glideslope
• APP switch light extinguishes after localizer and glideslope capture.
After localizer and glideslope capture, APP mode can be disengaged by:
• pushing a TO/GA switch
• disengaging autopilot(s) and turning off both F/D switches
• retuning the VHF NAV receiver.
While engaged in the APP mode:
• the A autopilot and Captain’s F/D use information from Captain’s
Course Selector and No. 1 VHF NAV receiver
• the 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 the two VHF NAV receivers can
cause disagreement between Captain’s and First Officer’s F/D displays
and affect A/P operation.
Note:
After localizer or glideslope capture, during a single channel autopilot
approach, CWS cannot be engaged by manually overriding pitch and/or
roll control forces. Manually overriding pitch and/or roll will cause
autopilot disengage. At autopilot disengage, the active Autopilot modes
will remain engaged.
Note:
During a dual autopilot approach and after FLARE ARM annunciation,
any attempted manual override of the autopilots may result in an autopilot
disengage.
