Seletar Airport is a Singapore civil airport administered by Changi Airport Group, at 21 Seletar Aerospace Road 1. The current CAAS AIP publishes runway 03/21, instrument and visual flight procedures, scheduled runway closure periods and noise-abatement restrictions. The operator provides separate guides for commercial-flight and private-jet passengers. Seletar offers an educational comparison with Changi’s larger hub infrastructure, particularly in business aviation, flight procedures and the management of airport operations close to surrounding development.
