§ 2.60.480. Runway foaming specifications.

A.

The Federal Aviation Administration Advisory Circular 150/5200-4 titled "Foaming of Runways" states the following:

1.

Runway foaming cannot be considered a panacea to assure that fire will not occur during an aircraft landing with a malfunctioning landing gear.

2.

When this service is provided, the airport must ensure that its firefighting and rescue potential is not reduced below that which is required to comply with the airport FAA operating certification.

B.

When an aircraft or a responsible official of a company or organization requests that a runway be foamed, the Nashville Metropolitan Airport CFR station will do so only under the following conditions:

1.

That a stock of foam concentrate over and above that required for firefighting operations is on hand to sufficiently satisfy the runway foaming service requirements;

2.

That the aircraft has sufficient fuel to await the time required for foaming that portion of a runway as requested.

Note: To foam a strip sixty feet wide by three thousand feet long requires thirty-five to forty minutes;

3.

That the operator, owner or insurer of the aircraft shall pay the actual expenses arising from providing the runway foaming service. Note: To foam an area forty feet wide by two thousand feet long requires four hundred eighty gallons of foam concentrate. At the present cost of foam at eight dollars and fifty cents per gallon, this service would cost four thousand eighty dollars.
