When should pilots state their position when calling the tower for takeoff?

A pilot should state their position when calling the tower for takeoff to ensure clear communication and avoid any misunderstandings regarding their specific location on the airport. This is particularly important when departing from a runway intersection, as it informs the tower of where the aircraft is on the runway and helps to prevent potential conflicts with other aircraft that may be using the same runway or nearby taxiways. By stating their position at the intersection, pilots enhance situational awareness for both themselves and the air traffic control personnel, which is crucial for maintaining safety in the busy environment of an airport.

In this context, it is not necessary for pilots to state their position only when cleared for takeoff, as this timing does not help the tower understand the aircraft's location relative to other traffic. Similarly, stating their position when nearing the airport or before entering the final approach is not applicable to the takeoff communication as they are focused on either arrival or approach procedures rather than departure. Therefore, the indication of position at the runway intersection is a key requirement for effective communication during the takeoff clearance process.
