Influence of workload on the neurological state of a pilot during the approach and landing.

Abstract : The present studies have emphasised the importance of workload patterns to the physiological changes which develop in a pilot during the approach and landing. The progressive elevation of neurological arousal in manual let downs, implicit in the shortening of the rr interval from top of descent, was modified by the technique of shared and coupled approaches, but gross finger tremor after landing, which is due to untoward events during the approach and around touch down, remained unaffected by the changes in flight deck workload patterns.
