This section covers normal modes of the autopilot during climb-
out and enroute operations as well as procedures, mode control
and display.
NORMAL OPERATING MODES
Envelope Protection is active in all coupled autopilot modes.
PITCH MODE
Pitch mode is the default vertical mode if no other vertical mode
was selected at time of autopilot entry.
There is no specific Pitch Hold button on the autopilot control
head and no way to alter the commanded pitch once in Pitch Hold
mode. In other words, pressing the “AP” button on the autopilot
control panel from the “AP Ready” state will put the airplane into
Pitch Hold mode. Similarly, pressing any one of the lateral mode
buttons on the autopilot control panel (HDG or NAV) only from the
“AP Ready” state will also engage Pitch Hold automatically.
In Pitch Hold mode, the autopilot will maintain a constant pitch
from the moment of mode entry. If the mode was entered at a
pitch that exceeds the maximum hold limit, the pitch will be
reduced to the maximum hold limit value.
The autopilot modes annunciator indication is green “
PITCH
”.
ROLL MODE
Roll mode is the default lateral mode if no other lateral mode was
selected at time of autopilot entry.
There is no specific Roll Hold button on the autopilot control head
and no way to alter the commanded bank once in Roll Hold
mode. In other words, pressing the “AP” button on the autopilot
control panel from the “AP Ready” state will put the airplane into
Roll Hold mode. Similarly, pressing any one of the vertical mode
buttons on the autopilot control panel (ALT or VS or IAS) only
from the “AP Ready” state will also engage Roll Hold
automatically.
