Why is it that in the airline industry the HUD seems to be a cheepo version of what the mil guys use?
AFAIK their flying relies a lot on HUD, no matter what attitude they are in.
Again, I can't relate to own experience, never flew in mil A/C nor used a civvy HUD.
At least this thread learned me why airlines choose for a HUD to make CAT 1+ landings, iso a dual A/P... They are way cheaper!
