PITCH ATTITUDE HOLD MODE
The pitch attitude hold mode is the basic vertical flight director mode.
It is activated when a flight director roll mode is selected without an
accompanying pitch mode. There is no annunciator for pitch hold mode,
as shown in Figure 8--33. The pitch command on the EADI shows the
pilot a pitch reference that corresponds to the pitch attitude that existed
when the roll mode was selected. This pitch reference can be changed
by pushing the TCS button on the pilot’s or copilot’s control wheel.
The reference pitch attitude can also be changed with the pitch wheel
on the turn pitch controller when the autopilot is engaged.
Pitch attitude hold is cancelled when a vertical mode is manually
selected or automatically captured.
