ABSTRACT

Fire on board an aircraft is a very serious hazard; all precautions must be taken to minimize the risk of a fi re starting. In the event that a fi re does occur, there must be adequate fi re protection on the aircraft. Fire protection includes the means of both detecting and extinguishing the fi re. The subject of fi re protection theory is a branch of engineering in its own right. Basic fi re protection theory is covered in this chapter to provide the reader with suffi cient information to understand how this theory is applied through aircraft electrical systems. The chapter focuses on the equipment and systems used to detect fi re and smoke together with the means of delivering the fi re-extinguishing agent.
