Which ATC unit should be contacted first at EFTA for stand clearance?

The correct answer is Academy Tower. In aviation, particularly in air traffic control (ATC) operations, the sequence of contacting ATC units is crucial for ensuring safety and efficiency on the ground and in the air.

Academy Tower represents the air traffic control function that manages aircraft in the vicinity of the airport, including those on approach and departure. When looking for stand clearance, pilots should communicate with the control unit responsible for overseeing the movement of aircraft on the runway and taxiways, which falls under the purview of the Tower.

Ground control typically handles the operations of aircraft on the ground, while the Tower coordinates the overall air traffic in and out of the airport, including the oversight of ground movements in relation to active runways. Thus, while Academy Ground could handle aspects of taxiing and other movements, the primary authority for stand clearance and ensuring safe transitions from gates to runways falls under the Academy Tower.

Emirates Control may pertain to various operational aspects but does not specifically handle local air traffic movement at EFTA. Therefore, contacting the Academy Tower is the correct procedure for obtaining stand clearance.
