## Abstract

A method of fire prevention/extinguishing for an aircraft runway is provided where the method includes: providing a supply of fire preventing/extinguishing chemical; disposing a piping system beneath a top surface of the runway and having an inlet in communication with the supply and an outlet in communication with the top surface; and delivering the fire preventing/extinguishing chemicals from the supply through the piping system and outlet to the top surface.

## Claims

### Claim 1

A fire prevention/extinguishing system for use on an aircraft runway, the system comprising:
a plurality of movable panels upon which an aircraft contacts;
a supply of fire preventing/extinguishing chemical;
a piping system disposed beneath at least one of the plurality of panels, the piping system having an inlet in communication with the supply and an outlet positioned to direct the fire preventing/extinguishing chemicals to a top surface of one or more of the plurality of movable panels; and
a pump for delivering the fire preventing/extinguishing chemicals from the supply through the piping system and outlet to the top surface,
wherein the outlet is disposed under one or more of the plurality of panels such that opening of the one or more of the plurality of panels exposes the outlet and the plurality of movable panels are hinged to rotate in a direction towards an incoming aircraft.

### Claim 2 (depends on 1)

The system of claim 1, wherein the piping system outlet comprises a plurality of nozzles disposed beneath the plurality of panels and configured to deliver the fire preventing/extinguishing chemical to the top surface.

### Claim 3

A method of fire prevention/extinguishing for an aircraft runway, the method comprising:
covering a portion of the aircraft runway upon which an aircraft contacts with a plurality of movable panels;
providing a supply of fire preventing/extinguishing chemical;
disposing a piping system beneath at least one of the plurality of panels, the piping system having an inlet in communication with the supply and an outlet positioned to direct the fire preventing/extinguishing chemicals to a top surface of one or more of the plurality of movable panels;
opening the at least one of the plurality of panels to expose the outlet; and
delivering the fire preventing/extinguishing chemicals from the supply through the piping system and outlet to the top surface;
wherein the opening comprises rotating the at least one of the plurality of panels in a direction towards an incoming aircraft.

### Claim 4 (depends on 1)

The fire prevention/extinguishing system of claim 1, wherein the outlet is oriented so as to direct the fire preventing/extinguishing chemicals to the top surface of the one or more of the plurality of movable panels other than the movable panel under which the outlet is disposed.

### Claim 5 (depends on 3)

The method of claim 3, further comprising orienting the outlet so as to direct the fire preventing/extinguishing chemicals to the top surface of the one or more of the plurality of movable panels other than the movable panel under which the outlet is disposed.

### Claim 6 (depends on 1)

The fire prevention/extinguishing system of claim 1, wherein the fire preventing/extinguishing chemical is a foam.
