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

A pilot should state their position when calling the tower for takeoff, particularly when departing from a runway intersection. This practice is essential because it allows the tower to have a clear understanding of the aircraft's location, ensuring safety and proper sequencing of takeoffs.

When departing from an intersection rather than the designated runway threshold, it is crucial to inform the tower of this specific position, as it affects the departure point and can influence the air traffic control sequence. The tower may need this information to manage other aircraft that might be in the pattern or on adjacent runways, thus ensuring the safe and efficient movement of all aircraft in the vicinity.

Making this call helps avoid potential conflicts and reinforces situational awareness for both the pilot and the air traffic controller, contributing to overall flight safety. While the other options involve various situations related to communication, they do not specifically emphasize the importance of stating position when the takeoff point is non-standard, like an intersection departure.
