in Finland (click the picture for more information).An airport crash tender is a specially featured fire engine designed for use at aerodromes and airports in aircraft accidents.

The features include a relatively good acceleration, ability to move on rough terrains outside the runway and airport area, large water capacity, foam tank, a high-capacity pump, and water/foam cannons with a good throw distance. Newer AR-FF vehicals also incorporate Twin Agent nozzles/injection systems to inject a stream of Purple-K dry chemical into the AFFF foam stream "knocking-down" the fire faster. Some also have Halotron tanks with handlines for situations that require a clean agent to be utilized. These features give the airport crash tenders a capability to reach an airplane rapidly, and rapidly put out large fires with jet fuel involved.

Some tenders have an elevated extended extinguishing arm called a Snozzle, giving a possibility to raise a water/foam cannon into the height of approx. 10 - 20 meters. Some arms have reinforced nozzles that can puncture through superficial structures of an aeroplane to fight a fire inside the fuselage. Relyea; Robert G., Garnett; Edward V.: United States Patent Application, February 8, 1993. http://patft.uspto.gov/netacgi/nph-Parser?patentnumber=5301756 . Snozzle

Standards ICAO (International Civil Aviation Organisation) has given standards and recommended practices on rescue fire fighting categories of civil aerodromes ICAO: Volume 1 - Aerodrome Design and Operations. Annex 14: Aerodrome Rescue and Fire Fighting Service (RFFS) requirements ICAO: Airport Services Manual. Part 1 - Rescue and Fire Fighting. 3rd edition, 1990 . National aviation authorities may have given even further requirements on aerodrome rescue and fire services.

The rescue fire services are based on a critical aircraft based on a statistical analysis of movements (take-offs and landings) on the airport. The aerodrome category is based on the size of the biggest aircraft taking a movement on the aerodrome. In addition, the number of movements of the critical aircraft is calculated, and the category can be decreased by one if the number of movements is lower than the standard describes. There are also minimum category levels based on e.g. the number of seats in the critical aircraft.

Depending on the airport category, the standards determine the minimum number of rescue fire-fighting vehicles. In addition, requirements are given on the water and foam capacities, discharge rates for foam solutions, and minimum dry chemical powder (complementary agent) amounts, reserve stocks of fire fighting agents, ability to operate on rough terrain, and acceleration of the air crash tenders. The end of each runway has to be achieved in a response time of two minutes, and any part of the movement area has to be achieved in a response time not exceeding three minutes.
