The study focused on the effects of runway capacity and air traffic control on the growth of aviation businesses. The guiding objectives of this study were: to determine the effect of runway capacity on the aviation business growth in Kenya and to evaluate the effect of air traffic control capacity on aviation business growth in Kenya. The study was guided by resource-based theory. The study employed an explanatory research design. The study targeted 117 respondents comprising 92 operational managers at Wilson Airport, 25 air traffic controls, and Kenya Airport Authority employees based at Wilson Airport. A Census survey was used in this study to collect information from all participants in the population. The study collected primary data using questionnaires. In testing for reliability, Cronbach’s alpha coefficient was applied. Statistical Package for the Social Sciences (SPSS) version was used for data analysis. The study findings revealed that runway capacity positively and significantly affects aviation business growth. Air traffic control capacity has a positive and significant effect on aviation business growth). It can be concluded that runway capacity at Wilson Airport is insufficient. Night-hour flying can enhance runway capacity, and by large, aviation growth as AOC holders can fly more due to increased operating hours. The aerodrome owner and operator should ensure that it boosts the existing runway capacity either by optimizing the operations or expanding to cater to business growth. KAA and KCAA, the regulators, should consider boosting the runway capacity through increasing navigation aids to enable the introduction of night flying. The study recommends that future researcher’s study on the influence of public, and private partnerships to increase the ground movement capacity on aviation growth can also be conducted
