Head-eye coordination during simulated orbiter landing.

Background: Orbiter landing data show decrements in pilot performance following spaceflight compared to preflight simulated landings. This study aimed to characterize pilot head-eye coordination during simulated orbiter landings, and relate findings to microgravity-related spatial disorientation.

Methods: Orbiter landings were simulated in an A340-300 simulator flown by six pilots.

Electronic pilot-activity monitor: a countermeasure against fatigue on long-haul flights.

Background: Previous studies have shown frequent reductions in aircrew alertness during long-haul flights, even during the critical descent phase. Recommended countermeasures include alternation of crew activity with rest, such as cockpit napping. However, a method of monitoring the alertness level of the active and napping pilots should be considered.
