HUD

I am not sure that I would want a HUD in a glider. It is distracting
enough trying to look out of the front window at the sky through the
various reflections on a glider canopy without having extraneous
instrument data out there too. The only gliding exception for me
would be an Artificial Horizon display - in that case the information
would be displayed in the same position as the natural horizon i.e.
the information displayed relates to what I am looking it (or would be
looking at if it weren't obscured) in the real world - similar to
military HUD display target data overlaying the real target.
