IMPLICIT AND EXPLICIT HORIZONS: LANDING APPROACHES UNDER RESTRICTED VISIBILITY CONDITIONS. IN: ENGINEERING PSYCHOLOGY AND COGNITIVE ERGONOMICS. AEROSPACE AND TRANSPORTATION SYSTEMS

This paper focuses on the perceptual processes in situations where sight conditions are restricted because of fog during landing approach. The functional utility of the horizon to control the glide angle visually to the runway is explained by H-hypothesis. The functional utility of the explicit and implicit H-angle was tested as a Gibsonian invariant controlling the visual glide slope, based on an ecological analysis of the optics during a runway approach under foggy conditions. Results, based on 40 participants viewing simulated landing approaches, indicate that subjects rather referred to the explicit than the implicit horizon when estimating the glide angle. There was no connection between participants' accuracy of the estimated implicit H-angle and the reliability of their glide angle judgements.
