Identification and Priority of Risky Factors Effecting on Aircraft Operation on Aerodrome and Flight Environment Around it

Aerodrome surface safety and in particular safety of flight environment around them are acknowledged globally as one of aviation's greatest challenges.
Aeronautical industries development within recent decays and employment of innovated technologies and procedures, encountered with multiple risk that threating the aviation safety.
The main purpose of this research was identification and priority of risky factors effecting on aircraft operation on aerodrome and flight environment around it.
In this survey, descriptive method was used and a questionnaire of 22 items prepared and distributed between the research statistical population including Tehran Province aeronautical personnel about 420 persons that 201 of them have been selected based on Morgan table as statistical sample. The reliability of the questionnaire have been confirmed by Cronbach`s alpha coefficients (0.8) and its validity checked by content, structural and Lawshe methods. SPSS software version19 plus SEM (LISREL 8/5) have been used for analyzing.
Research finding indicates that human factors, equipment factors, software factors and hardware factors have positive and direct effect on risk of aircraft operation on aerodrome surface and flight environment around it. Impact of human factors are 0.90, environmental factors .78, hardware factors 0.69 and software factors is 0.52.
Safety level enhancement is required on and in the vicinity of an aerodromes through planning and implementation of safety management system, knowledge and safety culture development for all human resources, in parallel to installation of new aerodromes equipment. At the end, it’s noted that coordination with relevant organization for preventing of potential danger shall be effected.
