The role of aircraft performance analysis is to enable airports to fully utilize the operating capabilities of aircraft on the premise of complying with airworthiness requirements. According to the airport construction project stage, it is divided into site selection stage, pre-research stage, master plan stage, research stage, preliminary design stage, and terminal design stage. The main consideration is whether the runway length and clearance conditions around the airport meet the aircraft's operation in a takeoff emergency.
