Future
Am reading some excellent input. Further out, don't be surprised if ATPL's will be wearing headgear with a HUD that stays oriented perfectly and consistently with various combinations of "Bundled" displays in the same position regardless of the direction of the Pilot's gaze. There is no reason to think this format would require much training, and notwithstanding the predictable uproar from Pelicans (guilty) it is a natural, allowing the best of panel scan and outside reference. I've been fortunate to try it, it's an outstanding system.
