The demand of the air transport is increased over time. This situation attracts the airlines to increase their supply. The airlines increase their supply not only by increasing flight frequency but also by replacing their aircrafts with the aircraft types that have larger seat capacity. Every aircraft has the limitation in terms of the operating permit. Airlines have to replace their aircrafts if their aircrafts reach the maximum age limit. Even, some types of aircrafts are no longer manufactured. It triggers the use of new types of aircrafts by the airlines. This study is conducted to assess the current aircraft types that still possible to be operated in Indonesia for 20 years based on Aircraft age. Those aircrafts are analyzed whether those types of aircrafts are allowed to be operated in the Achmad Yani aerodrome by simulating payload and range. The improvements of the airside infrastructures are proposed to optimize the aircrafts served. The analysis result shows that most of the current aircrafts operated in Indonesia are still possible to be operated until the next 20 years. By considering the aircrafts manufacture orders and the age of operated aircrafts, the current aircrafts that are still possible to be operated until 2031 are Boeing 737 classic such B737-300, -400 and -500; new generation of Boeing 737 such B737-800 and -900ER; the main competitor of Boeing 737 such A-319 and A-320; wide body aircrafts such B747-400, B767-300 and A330. According the analysis, an aircraft with ARC up to 4C such B737-800 and A320 can be operated in Achmad Yani aerodrome with maximum payload to serve farthest route from Semarang to Singapore. To serve the same route, the larger aircrafts such B737-900ER and B767-300 have to reduce the payloads carried because the pavement strength in section C cannot support the take-off weight. An overlay in section C to improve the pavement strength is required if B737-900ER and B767-300 will be operated to serve farthest route from Semarang to Singapore. Aircrafts types with ARC of 4E such B747-400 and A330 are not allowed to be operated in Achmad Yani aerodrome because the apron depth and pavement strength in section C do not adequate to support the operation of those aircrafts. The apron depth and pavement strength in section C should be adjusted if wide body aircrafts will be operated to serve farthest route from Semarang to Singapore.
