Which item is NOT typically provided by air traffic controllers to firefighters during an aircraft incident?

Air traffic controllers play a crucial role in assisting firefighters during an aircraft incident by providing vital information that can help manage the situation effectively. One of the main aspects they cover includes the current aircraft location, which is essential for determining how to approach and address the incident. Furthermore, details about the type of aircraft are shared, as this informs the responding crews about potential hazards, as well as the specific firefighting tactics that may be required.

The number of passengers on board can also be crucial, especially for planning resources and managing evacuations. It helps determine potential rescue needs and allows the firefighters to prioritize their actions accordingly.

While aircraft flight plans might include useful information regarding the trajectory and altitude of the flight up until the point of the incident, this data is not typically supplied to firefighters during ongoing emergencies. The flight plan may become irrelevant as an aircraft incident unfolds and fire crews focus on immediate response rather than the details of the flight’s planned route. Therefore, while flight plans have historical significance, they are not generally emphasized in the dynamic and urgent context of an aircraft incident, making this the correct answer.
