Air traffic control (ATC) is an important profession that directly affects the performance of flight operations in the air and on the ground. The fluctuating number of incidents and accidents in the aviation sector is as a result of various factors, in which safety culture is a vital factor in establishing the overall safety in aviation.  This research aims to assess individual perceptions and judgments of safety culture in practical contexts utilizing nine aspects of safety culture (Work situation, Learning, Communication, Risk perception, Attitude toward safety, Justness, Safety-related behaviors, Flexibility and Reporting). The safety culture was assessed using observations, questionnaire packages and interviews. This study pertains to the ATC staff in Mitiga International Airport, Tripoli, Libya. A number of 25 samples of the suggested questionnaires were collected, along with a numeral of interviews. Assessment of the nine aspects were found to function well with good reliability (internal consistency) with (α) value above 0.8. A five-point Likert Scale was used. Assessment with gained results of mean, standard deviation and variance showed medium average scores in the nine aspects. An individual characteristic such as experience was found to have very little effect on how the safety culture aspects were perceived and judged.
