Due to ICAO requirements, for example at the Helsinki-Vantaa airport there are several airport crash tenders located on several fire stations. Airport crash tenders are able to rapidly put out fire on large aircrafts, and foam runways in situations of preparedness, for example, if difficulties are expected in landing.
The 31 metric ton, 6x6 air crash tender in the picture has an engine with output of 600 hp (441 kW), crew space for 1+3, seat-integrated breathing apparatus fittings, 12 000 l water tank, and 1500 l foam tank. The pump has a capacity of 7000 l/min, and the monitors (water/foam cannons) outputs of 1000 l/min and 5000 l/min. The larger cannon has a throw distance of 70 – 80 meters. The maximum operational speed is 115 km/h, and acceleration from 0 to 80 km/h takes 32 seconds. In addition, the unit is equipped with powder, several lighting masts, aggregator, a self-protecting system with several ground sweep nozzles. Some units may have also a thermographic camera which is used to locate fire in poor visibility and smoke, and to control possible overheated parts and areas. The units are also equipped with normal fire fighting hoses.
This air crash tenders can be operated by one man only, which gives a possibility to use several airport crash tenders with a relatively small amount of personnel. In situations of preparedness and real accidents or fires the airport fire brigade is supported by the aerial fire brigades located nearby.
In addition, the airport fire brigade may have other kind of vehicles, like light command unit, fire chief’s vehicle, ambulances, rescue units, and/or engines. These units take care of the airports daily operative tasks. For example, at the Helsinki-Vantaa airport one engine is equipped like a normal engine, running tasks outside the aircraft movement area, and carrying first response equipment.
