Abstract:

An investigation of terrain-following flying at high speeds on a Hunter aircraft is described and examples are given of the flight paths achieved and the normal accelerations developed. Fatigue meter data are used to provide a measure of flight bumpiness and show good correlation with pilots opinions. The possible effects of aircraft structural vibrations on crew comfort are considered and results given of tests made on a Canberra aircraft to assess the usefulness of a spring-mounted seat, for a range of frequencies and damping a marked improvement in comfort was found with certain spring characteristics. Impressions of comfort on both aircraft correlate well with the RMS of rate of change of acceleration. Author
