The Boeing-style CDU as seen on a Boeing 747-400.

FlightGear has a generic Control Display Unit (CDU) model available, for easy implementation into aircraft. Currently only a Boeing style one is available, under Aircraft/Instruments-3d/cdu/. Be sure you have implemented a V-speed calculator before implementing the CDU.

The Boeing 747-400 is an example aircraft for the generic CDU.

model .xml

For each single CDU unit, the following code block is required in your aircraft's model .xml file. You can add as many CDUs as you need.

<model>
 <path>Aircraft/Instruments-3d/cdu/boeing.xml</path>
 <offsets>
  <x-m> 0.858</x-m>
  <y-m> 0.186</y-m>
  <z-m> 0.489</z-m>
  <pitch-deg>-75</pitch-deg>
 </offsets>
 <overlay>
  <texture>boeing_brown.png</texture>
 </overlay>
</model>
  • offsets: use these to position the CDU in your cockpit. The CDU model's origin is in the center of the model.
  • texture: currently there are two textures to chose from, in order to fit your aircraft's panel color:

-set.xml

These should all be placed outside the <sim></sim> part.
