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

Pilots should state their position on the airport when departing from a runway intersection because this informs the air traffic control tower of their exact location and enhances situational awareness. By providing this information, pilots help ensure that the tower has a clear understanding of their position relative to other traffic and runway usage. This communication is particularly critical at airports where multiple runways intersect and could potentially lead to confusion or conflicts if not clearly communicated.

When departing from a runway intersection, there might not be sufficient visibility of the entire runway length, and other aircraft may be using the same runway or nearby runways. Therefore, clearly stating which intersection they are at allows the tower to give informed and safe clearance for takeoff or hold, thereby facilitating a safe and efficient traffic flow in a busy airport environment.
