PMDG MD-11
We have offered a couple of different options to suit customer taste, as
some customers do not find that manual override authority is helpful
given the nature of some flight control hardware.
You can choose to override the flight controls always or never. If
selected, it is possible to override steering commands to the autopilot by
deflecting the flight controls slightly. When the controls are released the
Autopilot will return to following commands from the flight director.
If this
option is de-selected, manipulation of the controls while the autopilot is
engaged will have no effect, unless the controls are deflected beyond a
certain point in which case the autopilot will disengage and return control
of the airplane to the pilot.
Similarly, you can choose to override the autothrottle by manually
repositioning the throttles at any time, or only while they are operating in
CLAMP mode.
Please Note: PMDG receives a significant amount of email from
customers who report that the autopilot occasionally disconnects
“for no reason.” Upon investigation we usually find that the user’s
joystick is out of tune and/or exhibits signal spiking behavior. This
spiking behavior is interpreted by the airplane as a pilot attempt to
override the controls.
To fix this, re-center the joystick and/or increase the null zone if you
are unable to eliminate the spiking.
Joystick Sensitivity for LSAS/RCWS:
The MD-11 uses Lateral Stability
Augmentation System to make the airplane simpler to fly. LSAS is a
hybrid implementation of automated pitch and roll management with
conventional aircraft flight controls.
LSAS operates continually so long as it is not disabled by the flight crew,
except for brief periods during takeoff and landing. Some users may find
that they want to adjust the sensitivity of LSAS to their unique flight control
hardware. You can do this using the LSAS/RCWS sensitivity control
slider.
