What is the primary method of firefighting foam application for aircraft fires?

The primary method of firefighting foam application for aircraft fires is through an induction system. This approach is specifically designed to maximize the effectiveness of the foam, which is essential in suppressing flammable liquid fires, such as those that may occur during an aircraft incident. The induction system mixes the foam concentrate with water as it is ejected through a nozzle, creating a foam blanket that can smother flames and cool hot surfaces.

This method is particularly advantageous during aircraft firefighting because it allows for precise control over the foam application, ensuring that it covers the burning surfaces uniformly. Proper foam delivery is critical in preventing re-ignition and controlling fire spread, thus enhancing the safety of both the aircraft occupants and the firefighting personnel involved.

In contrast, alternative methods like direct application or fogging techniques might not provide the same level of coverage and effectiveness against the intense fire conditions often present with aircraft incidents. Water-throwing techniques also lack the specific benefits of foam, as water alone is less effective on fuel-based fires without the suppression properties that foam provides.
