Cockpit thermal stress and aircrew thermal strain during routine Jaguar operations.
Thermal data have been obtained from Jaguar aircraft flying routine, warm-weather operations in Sardinia. These data have been analysed in terms of the ambient and cockpit wet bulb globe temperatures (WBGT) and the mean body temperature (Tb) of the pilot. In contrast to similar data previously obtained from Harrier and Buccaneer aircraft, no interrelationships could be demonstrated between ambient WBGT at ground level and either cockpit WBGT or pilot Tb. Relationships which could be described by equations of negative slope were obtained between Tb and sortie time and between cockpit WBGT and sortie time. A model has been derived for predicting aircrew thermal strain in the Jaguar from cockpit temperature and sortie time.
