Fire Apparatus USA 21
Fire Apparatus USA 21 : Types (10): Airport Crash Tender: The International Civil Aviation Organization (ICAO) has given standards and recommended practices on rescue firefighting categories of civil aerodromes. National aviation authorities may have given even further requirements on aerodrome rescue and fire services. The rescue fire services are 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, for example, the number of seats in the critical aircraft. Depending on the airport category, the standards determine the minimum number of rescue firefighting 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 must be reached 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
