Air traffic control tower[edit]
The Air traffic control tower (ATC) was constructed as part of Phase One of the Changi Airport redevelopment plan and it is 80 meters high.
T4 will also have its own Ramp Control Tower to oversee and manage aircraft movements in the apron and taxiways around the terminal. This tower is needed to enhance the Changi Airport air traffic controllers’ visual line of sight of aircraft parking stands and associated taxiways near the southern end of Runway 2. The 68-metre tall Ramp Control Tower will provide clearance to pilots on when they can push back from the gates, as well as give instructions on which taxiway to be used, before handing over communications to the Changi Air Traffic Control Tower.
