4.2.2.6 Optional Autotrim
If the autopilot is equipped with optional Autotrim, the aircraft elevator
trim will be maintained automatically when the Trim Master Switch is ON
and a pitch mode is activated.
When the Trim Master Switch is ON, the trim annunciators are disabled.
If the switch is OFF, or a power failure occurs, the annunciators
automatically become functional.
The trim system is designed to accept any type of single failure,
mechanical or electrical, without uncontrolled operation resulting. To
ensure that no hidden failures have occurred, conduct a trim preflight
check prior to every flight. (Consult the appropriate AFMS or POH.)
4.3 Flight Director Operations (Optional)
4.3.1 Single Cue
This system, which integrates both the roll axis, and pitch axis, offers
synchronized display of the flight profile. It is automatically activated
when the autopilot pitch axis is engaged. A Flight Director provides a
visual indication of how accurately the pilot or autopilot is tracking the
commands of the active mode of operation.
Activation is indicated by illumination of the FD annunciator. A remote
parallax adjustment is provided to change the height of the horizontal
display to compensate for different seat heights. And a remote switch
allows manual flight control via Flight Director commands.
For proper flight technique, the system presentation requires the pilot to
roll and pitch the aircraft toward the display until the delta shaped
reference is tucked into the steering command bars, indicating that
commands have been satisfied. For example, if the display is up and
left, the pilot would be required to establish a left turn, pitch up attitude.
As bank angle and vertical speed approach the required amounts, bank
angle and pitch up attitude are shallowed. When the delta reference and
the steering bars are matched, the commands have been met. Thereafter,
it is necessary to maneuver the aircraft to keep the display elements
matched in order to accurately fly the selected modes.
Accurate flight director operation requires alertness by the pilot and
monitoring the movement of the display. Keeping it matched is quite
simple. However, control inputs must be timely and smooth for accurate
flight director following of the desired command.
For manually controlled flight by the flight director, place the FD master
switch in the ON position, and the autopilot master switch in the OFF
position. This disables the autopilot servos, allowing the pilot to control
the aircraft to flight director commands. To return to autopilot flight simply
move the AP switch to "ON".
