In designing an aircraft as a man-machine combination, it is neccessary to find the best compromise among various requirements, such as performance, reliability, economy etc., which may conflict with each other. The problem is made increasingly difficult by requirements for interior accomodations such as seat comfort, illumination, etc.; protecting the crew from temperature and pressure change and from noise; providing the aircraft with suitable automatic equipment to ease the work load and adaptability of the crew; and finally making the aircraft really pleasant to fly. From the stand point of an aircraft designer it is highly desired that for each requirement mentioned above suitable human engineering theories or data are furnished. Human engineering must be a joint consideration along with aircraft engineering for a successful aircraft design.
