The authors reviewed studies of cognitive proficiency and flight perfo
rmance. Age-group differences were found in pilots in perceptual-motor
skills and memory and, to a lesser extent, in attention and problem s
olving. Flight experience does not alter this age-related decline, wit
h the possible exception of the metacognitive skill of time sharing. A
ge-group differences in flight performance are most evident in the sec
ondary task of air traffic control communications. Age-related differe
nces in current measures of pilot cognition are minimally predictive o
f primary measures of flight performance (flight simulation and accide
nt rates). A model of cognition and flight performance is proposed inv
olving higher order factors that tap into pilot knowledge structure, i
ncluding mental workload and workload management, mental models, and s
ituation awareness.
