An investigation of takeoff and climb NOₓ emissions is reported for a twin-engine, narrow-body, short-to-medium haul commercial aircraft, B737-800. Ten randomly selected flights are considered for two independent domestic routes. The study is based on two approaches: actual flight data records and the International Civil Aviation Organization (ICAO) emission database. First, an empirical model is established in order to identify the relationship between fuel flow and a NOₓ emission index. Next, the NOₓ emissions are analyzed through the vertical air region and the horizontal distance from the runway. Averaged takeoff and climb NOₓ emissions for equal vertical regions for each route are found as 27.0kg and 24.8kg through the developed models for two routes, A and B, respectively. The results are also compared to those given in the ICAO database which utilizes standard takeoff and climb emission indices.
