Category 2 - A Simulation Study of Low Visibility Approaches and Landings at Night.

摘要

The report describes the design,execution and results of a flight simulator experiment to investigate the problems of aircraft operating in Category 2conditions. Both military and airline pilots participated and over 500manual approaches were performed using a flight director. The effects of decision height,contact time,lateral offset,visual sequence and visual segment on the approach success (the ratio of landings to approaches) are examined and a curve relating this parameter to visual segment,the predominant factor,is determined. The influence of different visual sequences on pilot performance during the approach and landing is also considered and some observations are made about the crew techniques employed during the experiment;techniques which appeared to have certain deficiencies.
