Thanks for the response.
How do you implement a 2D hud? I can't find any documentation on this, and it apparently is defaulting to 3d behavior.

To my recollection (and the complete README.xmlhud in
FlightGear/src/docs-mini should provide more hints) the HUD is always
treated as being 800x600 pixels with (0,0) at the bottom-left side of
the screen (like OpenGL).

There are two types of HUD, one in 2D view (always visible straight
ahead) and the 3D HUD which tries to keep the HUD displayed a the same
location, always facing the same direction in the 3d scene.
You probably want to use the 2D HUD for this.
