During hot summer weather at CFB Portage la Prairie, measurements were made of the heat stress experienced in the cockpits of the Musketeer aircraft and the Kiowa helicopter while stationary not-running on the runway and during flight. It was found that severe heat stress can occur in either cockpit when monitored in closed configuration, either on the ground or in flight, and that such heat stress can lead to dire physiological strain in less than one hour. Use of air vents on the Musketeer aircraft did not completely ameliorate the cockpit heat stress problem and added considerably to communication difficulty because of wind nose. Air conditioning is recommended for alleviation of heat stress in this aircraft. It was found that no difference existed between the cockpit stress and ambient heat stress when the Kiowa aircraft was flown without its doors and it is recommended that this practice be encouraged during warm or hot weather to reduce pilot strain.
