thanks, i wil look in pmdg.
these are the functions, all the other functions are working only the pull functions not yet.
1) Airspeed on the MD-11 is controlled by setting the speed
manually in the speed window, or by turning speed control over to
the FMS. There are three different functions you can access
using the airspeed knob:
a. To hold the current airspeed, PUSH the knob to activate
SPEED HOLD at the current airspeed.
b. Rotating the knob allows you to set a new target speed.
c. To command the autopilot to adjust speed in accordance
with the speed you have set in the window, PULL the
knob.
2) Heading on the MD-11 is most often controlled by a heading bug,
or by turning navigation over to the FMS. There are three different
functions you can access using the airspeed knob:
a. For hold your current heading PUSH the knob enter HDG
HOLD mode.
b. Rotating the knob allows you to set a new desired
heading.
c. To command the autopilot turn to the heading bug, PULL
the knob. (The airplane will always follow the heading
bug.)
3) Altitude on the MD-11 is controlled manually, or in PROF (profile)
mode. For manual control of altitude:
a. For manual altitude control, PUSH the knob to enter
altitude HOLD mode.
b. Rotate the knob to select a desired altitude.
c. PULL the knob to initiate a climb or descent to capture the
new altitude. This type of climb is very similar to FLCH in
a Boeing airplane.
d. You can also initiate a climb by setting a new altitude in
by ROTATING the knob, then using V/S to climb or
descend. (Or you can enter the climb/descent using V/S
and then pull the altitude knob to continue the
climb/descent.)
