Automatic Flight -
System Description
MN-FLT-OH-201 4.20.29
During an approach without FLARE arm or FLARE engage displayed, if TO/GA
is pressed with LNAV arm annunciated on the FMA, the flight director LNAV
mode will engage when the airplane is above 50 feet. Below that altitude the mode
will be track hold.
Single channel autopilot minimum engage and use heights are not affected. This
feature is recommended to support RNP RNAV operations for terminal
procedures requiring definitive course guidance.
Go-Around Roll Mode – LNAV in Lieu of Track Hold
1B785, 1J585 - 1J594
(for Fail-Operational fleet)
When multiple arm modes such as LNAV and ROLLOUT are set, they will appear
on the FMA side by side in white.
When a missed approach exists in the flight plan and the FCCs are capable of
entering go-around, LNAV arm will be annunciated on the FMA. The roll
go-around track hold mode will automatically transition to LNAV during a missed
approach.
During autoland operations with LAND 2 / LAND 3 displayed and both engines
operating, if TO/GA is pressed with LNAV arm annunciated on the FMA, then
LNAV will engage when the airplane is above 400 feet. Below that altitude the roll
mode will be track hold.
During an engine-out condition and both autopilot channels engaged, the LNAV
arm annunciation will be removed from the FMA, if TO/GA is pressed the roll
go-around mode will remain in track hold.
During an approach without LAND 2 or LAND 3 displayed, if TO/GA is pressed
with LNAV arm annunciated on the FMA, the flight director LNAV mode will
engage when the airplane is above 50 feet. Below that altitude the mode will be
track hold.
Single channel autopilot minimum engage and use heights are not affected. This
feature is recommended to support RNP RNAV operations for terminal
procedures requiring definitive course guidance.
