BACKGROUND: Adequate instrument scanning is considered an important countermeasure against spatial disorientation (SD). Remarkably, literature on the relation between SD and pilots’ visual scanning is scarce. The objective of this simulator study was to investigate the influence of SD on pilots’ visual scanning and flight performance. METHODS:...

In a collaborative research project, TNO and the Royal Netherlands Airforce (RNLAF) developed an integrated hypoxia testbed in a moving-base flight simulator. The new hypoxia flight simulator environment aims to improve the operational realism of hypoxia training, and enables research on the effects of hypoxia in relation to flight tasks.

When operating an airplane, pilots perform a repetitive systematic visual scanning of the instruments, referred to as crosschecking, to update their mental model of the situation and to effectively apply control inputs. The recording of pilots’ viewing behavior with a gazetracking device can be useful in research on the pilot’s mental state,...

We investigated the performance of 12 airline pilots in recovering from an asymmetrical stall in a flight simulator featuring an extended aerodynamic model of a transport-category aircraft, and a centrifuge-based motion platform capable of generating enhanced buffet motion and g-cueing. All pilots had difficulties in applying the correct...

This article reports on an exploratory study in a fixed-based simulator to investigate the possible advantage (more presence) and disadvantage (more simulator sickness) of enhancing the visual realism in terms of head-slaved motion parallax. The study was performed in a flight simulator. Since most tasks involved taxiing over a virtual airfield,...

Motion sickness symptoms and increased postural instability induced by motion pictures have been reported in a laboratory, but not in a real cinema. We, therefore, carried out an observational study recording sickness severity and postural instability in 19 subjects before, immediately and 45 min after watching a 1 h 3D aviation documentary in a...

This paper describes two simulator experiments studying how accurately pilots can judge and reproduce specific g loads and how their control behavior depends on the sensation of physical g loads during unusual attitude recovery. Seventeen commercial pilots participated. The first experiment shows that pilots tend to overestimate g loads,...

This paper investigates how pilots' control behavior and motion perception during a simulated roll maneuver depends on the level of normal g load using a centrifuge-based simulator. Fourteen commercial pilots participated in the study, actively controlling a series of coordinated bank angle changes between -30 and +30 degrees. By changing the...

The aim of the collaborative European research project ‘Simulation of UPset Recovery in Aviation’ (SUPRA) is to develop breakthrough simulator technologies for teaching pilots to detect and recover from adverse flight upsets that could lead to unusual attitudes and loss-of-control. In the project, the high-performance research simulator...
