RESUMO
Globally, airlines are dedicated to achieving higher standards of Flight Safety. They have therefore developed and applied programs such as CRM, LOFT, Risk Management and Threat and Error Management. Despite these efforts, Commercial aircraft accidents continue to occur. Accident statistics over the last 40 years show that mechanical or maintenance related accidents comprise only 15% of the total, and have been decreasing. Accidents attributable to flight crew, however, are about 65% of the total, and show little trend towards reduction (Boeing, 2003). So there is much continuing effort to reduce these kinds of accidents. Additionally, many researchers world-wide are developing and applying programs which are focused on Human Factors. This study analyzes both the factors affecting flight crew and the results obtained from research conducted in Korea.

BACKGROUND: The physical environment (noise, temperature & humidity, microwaves, and jet lag) in the cockpit of air-transportation airplane is well known to have adverse effects on flight crew. But due to airplane security reasons and so on, the true environment could not be fully assessed up to now. The object of this study was to measure the status, to examine the effects of the environment, and to suggest the protection from them. METHODS: The status except jet lag was measured from the first officer seat in the B747-400/ B737-400/500 cockpit at several flight stage (pre-flight, after engine start, take off, climb, cruise, descent). Jet lag was examined through a flight crew schedule for 45 days. RESULTS: Noise level (74-84 dB), humidity (19%), microwaves(well above the caution and dangerous range), and jet lag (not enough to adjust from flight) were measured. The physical environment was examined which had considerable adverse effects on flight crew. CONCLUSION: The flight crew should be aware of the status which increase work load and physical load during flight. They must leave the cockpit as much as possible while they are off duty and be isolated from such status during rest.
