The study aimed to examine the impact of air navigation services quality on the competitive advantage of the Sana’a Flight Information Region in light of international sustainable development requirements at the General Authority of Civil Aviation and Meteorology in the Republic of Yemen. To achieve this objective, the study adopted a quantitative approach using a descriptive-analytical method. A questionnaire was used to collect primary data on the independent variable (air navigation services quality), the dependent variable (the competitive advantage of the Sana’a Flight Information Region), and the mediating variable (international sustainable development requirements). A census approach was employed, and the questionnaire was distributed to 120 employees and air traffic controllers in the Authority’s air navigation sector, of whom 98 responded. The data were analyzed using the Statistical Package for the Social Sciences (SPSS). The study yielded the following findings:
- , according to the respondents’ perceptions. The reliability dimension ranked highest, with a mean of 5.699 and a standard deviation of 1.082, while the tangibility dimension ranked lowest, with a mean of 3.578 and a standard deviation of 1.152. The overall mean for air navigation services quality was 5.044, with a standard deviation of 0.991. These findings answered the second main research question and fulfilled the study’s fifth objective.relatively highThe level of air navigation services quality in the Sana’a Flight Information Region was found to be
