INQUIRY INTO MUTUAL RELATION AMONG FLIGHT CREW BEHAVIORS, REMAINING TIME AND FLIGHT SAFETY

Based oh the statistics provided by the Flight Safety Department of CAAC on the flight and aviation ground accidents and incidents that took place during the five years from 1996 to 2000, the present article has made a series of systematic screening analysis of the possible causes and faults that may lead to such flying disasters. Our research has shown that there may have existed some close relation among the aircraft pilots' improper manipulation and the remaining time for them to cope with the emergency problems. The given discussion and analysis has been made by the authors of this article over the cases with the corresponding flight experts in hoping to inquire into the relations among such factors. Among the 11 flight accidents and 133 flight incidents that had been screened out, 3 flight accidents and 96 flight incidents took place due to the flight crew's failure in monitoring the operating instruments and the aircraft conditions or their failure to detect the faults occurring during the flight. Therefore, it is their improper manipulation that has made them leave little remaining time to take any additional emergency measures to deal with the faults. The other 8 flight accidents and 37 flight incidents took place due to the pilots' failure to make necessary decisions. The above research and analysis shows that, on the one hand, the pilots' behaviors may well decide whether enough remaining time is left for them, on the other hand, the emergency measures that they may take may well be influenced by the remaining time. Furthermore, the two factors may well be crucial to decide if such accidents and incidents can be avoided.
