- Military accident rates per 100,000 flying hours for all accidents and for those in which spatial disorientation was a factor. Comparison of the two 10-year periods, 1983–1992 and 1993–2002, shows a fall in overall accident rate, more evident for rotary-wing than for fixed-wing aircraft, but there was no decrease in the incidence of disorientation-related accidents. For comparison, the accident rate for scheduled commercial aircraft with a maximum take-off weight (MTOW) greater than 2,500 kg is 0.4 per 100,000 departures [15].
