From 1969 through 1972, 78 Navy helicopters crashed at
sea with a loss of 63 lives (10 due to injuries; the remaining
53 persons either drowned or were lost at sea). To
reverse the trend toward fatalities following aircraft
crashes at sea, the Navy has begun training all flight personnel
in the 9D5 Multi-place Universal Underwater Egress
Trainer. This thesis examined the relationships between
trainee performance (n=267) in the 9D5 device, swimming test
scores and subjective anxiety scores. Mile-swim times were
predictive of group (but not individual) performance in the
9D5 device with faster swimmers performing better. Poor
egress performance when blindfolded was attributed to egress
path difficulty and disorientation. Findings can be applied
to the design of egress aids, training and motivation of
subjects and the effects of anxiety upon subject performance
in carrying out sequential tasks while totally
immersed in water .
