TAKEOFF SUBMODE
The Takeoff submode provides Wings Level and fixed pitch up attitude
command indicated by the Flight Director command bars on the EADI.
The pitch angle is the same as described in Takeoff - Normal
Procedures (1-02-40).
This submode is annunciated by the ROL label and TO label, both on
the PFD, and it is canceled if any of the following conditions occur:
− The TCS button is pushed.
− The ALT, SPD, VS, or FLC mode is selected.
− Transition to capture Altitude Preselect mode occurs.
− Air data computer source selection is changed.
If the autopilot is selected with the Takeoff submode engaged, this
submode drops into Pitch Hold mode and synchronizes to the current
attitude. This submode does not couple to the autopilot, which may be
used after climbing above the airplane Minimum Engagement Height
(MEH).
A Pitch Limit Indicator (PLI) is displayed on the EADI sphere when the
margin prior to the stick shaker set point is lower than or equal to 10°.
In the case of an invalid Stall Protection Computer signal, the PLI will
be biased out of view and an amber AOA annunciation is displayed on
the PFD.
GO AROUND SUBMODE
The Go Around Submode should be selected once the decision to
discontinue the approach has been taken. Although commanding a
nose up attitude, the need to maintain wings leveled causes this
submode to incorporate both lateral and vertical modes features.
The autopilot may be coupled to the Go Around Submode above the
Minimum Use Height (MUH). However, the crew is not alerted in case
of coupling this submode below the MUH.
