Doshan Tappeh airport (IATA: OIID) is located in the Piroozi street (Formerly Farahabad) southeast of Tehran, the capital of Iran. It is in the middle of IRIAF main base. Nowdays the airport is closed since it is sorounded by the houses and other urban areas. In the lase decade the airport was used as a flight training base for IRIAF and there was some glider and kite flights within it, but now all of the flights are stopped. The airport runways are still in operational conditions to serve emergency flights during probable earthquake or other accidents in the eastern Tehran. This airport and other offices of IRIAF have occupied a lot of space in urban area of eastern Tehran and are one of the main reasons of very heavy traffic in Piroozi street and Damavand street.
