What becomes of the airspace during a forest fire?

In the case of a forest fire, the airspace is typically classified as Class F, which is a special use airspace. This classification allows for the establishment of a restricted area, ensuring that other aircraft do not interfere with firefighting operations. The designated Class F airspace can extend from the surface to a specified altitude, often cited as 3000 feet AGL (Above Ground Level), with a defined radius to ensure that the area is clear of non-participating aircraft.

Class F airspace is utilized for a variety of purposes, including military operations and, in this case, managing the airspace around an active forest fire to prioritize safety and operational effectiveness. By designating the airspace in this way, authorities can maintain control and communication with aircraft involved in firefighting efforts and ensure that other air traffic avoids the area, thus promoting safety for all involved.

The other options fail to accurately reflect the regulations regarding airspace management in response to emergency situations like forest fires, which is why they do not apply in this context.
