Human Factors Evaluation of the Argus (CP-107) Aircraft

Abstract : A human factors evaluation of the Argus (CP-107) aircraft was carried out during three Northern Patrols totalling 49.3 hours. About 180 adverse comments on the human engineering of flight and tactical crewstations are listed in detail. Measured noise levels at the Radio Operator's ear are shown to he potentially hazardous in hearing. Calculations show that active sonar returns of up to at least 70 dB SPL will be masked by rhe aircraft noise. Similarly, auditory processing of transient passive sonar information will be impaired. General habitability is seen to be grossly inadequate for the aircraft's present role. Suggestions are advanced for short - and long- term measures which might be adopted to improve comfort and operational efficiency
