Flare
The A/P flare maneuver starts at approximately 50 feet RA and is completed at
touchdown:
1B785, 1J585 - 1J594
• FLARE engaged is annunciated and with LAND 3 annunciated (as
installed), F/D command bars center.
• the A/T begins retarding thrust at approximately 27 feet RA so as to
reach idle at touchdown. A/T FMA annunciates RETARD.
• the A/T automatically disengages approximately 2 seconds after
touchdown.
1B401, 1B402, 1B786 - 1B824
• the A/P must be manually disengaged after touchdown. Landing roll-out
is executed manually after disengaging the A/P.
Rollout
1B785, 1J585 - 1J594
(as installed)
ROLLOUT arms when LAND 2 or LAND 3 annunciates.
At approximately two feet radio altitude, rollout activates:
• ROLLOUT replaces the VOR/LOC roll flight mode annunciation
• the autopilot controls the rudder and nose wheel steering to keep the
airplane on the localizer centerline
• rollout guidance continues until a full stop or until the autopilots are
disengaged.
Approach (APP) Mode Single A/P
A single A/P ILS approach can be executed by engaging only one A/P in CMD
after pushing the APP mode select switch. Single A/P approach operation is the
same as dual, with the following exceptions:
• full automatic flare and touchdown capability is not available. FLARE
is not annunciated and stabilizer trim bias is not applied
• if the pilot is flying manually but not following the approach flight
director guidance and then selects an autopilot CMD engagement, the
autopilot reverts to CWS for the pitch and/or roll mode. The approach
mode(s) will then re-arm.
• A/P status of SINGLE CH is annunciated for the entire approach after
localizer capture
• an A/P go–around is not available.
• after localizer or glideslope capture 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.
