title: Air operations and circadian performance rhythms.
abstract: This paper reviews experimental results and pertinent data from the literature on circadian behavioural rhythms and their modifications through various factors. It relates them to the operation of aircrews "round the clock" and on transmeridian routes and discusses some possibilities of an appropriate scheduling.
