The American Airlines HUD is BAE. Only used on the 737-800 which is the only 737 we have.

For one of the posters above,

HUD's are useful because it/they eliminate the daily autopilot/autoland confidence checks by maintenance that are time consuming for maintenance. At least that is what I was told.
Generally, HUD's installed are a half a million dollars.
At AA they are mandatory for use on T/O to help against tail-strikes since we do Flaps 1 T/O's for better second segment climbs (if i remember properly).
