Most single-pilot military aircraft are now being designed with head-up displays (HUD). The HUD has given the pilot a flight and weapon aiming display which has enhanced the safe operational flight envelope and the flexibility of weapons delivery. But has it benefited from the vigorous integrity analysis which has been given to other flight critical systems? The traditional pilot's instrument panel has both main and standby instruments laid out in a prescribed pattern for efficient scanning. The pilot has responsibility for crossmonitoring between these totally independent systems and for making a judgment in the event of deviance. Pilot monitoring, albeit over a much larger scan area, was also assumed when HUDs were introduced into the cockpit. This resulted in significant increases in physiological and psychological workload. This first generation of HUDs earned themselves a reputation for poor reliability and for a high occurrence of erroneous, but plausible, displays. This unsatisfactory performance has frustrated attempts to classify the HUD as the primary flight display and has forced responsibility for display monitoring onto the pilot.
