Abstract

In the long run, the fatigue in aircrews performing frequent, long-range flights is linked to factors connected to the aircraft, such as noise, temperature, cabin pressure, atmosphere quality, and flight characteristics. These are the factors inherent to the aircraft which we have investigated during six long-range flights without time zone changes in DC-8 and DC-10 aircraft of the U.T.A. Cie. The results show that none of the pollutants researched reach doses considered hazardous by FAR 25 or by French legislation. This fact is due to the effective ventilation in the cabins. In flight, thermal comfort is limited by a too-low hygrometry RH = 12%. Even in a modern aircraft, the noise level remains high, but acoustical energy is spread over the less detrimental frequencies.
