What distinguishes an airfield rescue tender from a standard fire engine?

Airfield tenders require significantly higher acceleration, top speeds, off-road capabilities (4x4/6x6), and specialized extinguishing media combinations (AFFF and DCP) specifically for aircraft fuel fires.

What are the primary extinguishing media carried?

They primarily carry large volumes of water and foam compound for fuel fires, supplemented by dry chemical powder or complementary agents for engine/electrical fires.

Do these vehicles need off-road capabilities?

Yes, they must be capable of navigating soft ground, ditches, and uneven terrain surrounding airfields to reach a crashed aircraft, requiring high ground clearance and specific approach/departure angles.

This standard specifies the functional, operational, and equipment requirements for rescue and fire fighting tenders designed specifically for airfield use. It outlines chassis specifications, vehicular performance metrics like acceleration and off-road mobility, and the minimum extinguishing media and rescue equipment required to handle aircraft emergencies.

Functional Requirements for Rescue Tender for Air Fields

Quick Reference Values

Drive configuration4x4 or 6x6 for off-road mobility

Minimum top speed> 100 km/h for rapid response

Acceleration (0-80 km/h)Typically within 25 to 40 seconds depending on category

Approach and departure anglesMinimum 30 degrees

Minimum ground clearanceNot less than 350 mm under the axles

Practical Notes

Vehicles must meet stringent acceleration and top speed requirements to comply with International Civil Aviation Organization (ICAO) response time mandates.

Weight distribution is critical; the fully laden vehicle must maintain stability during high-speed turns on airfield terrain.

Pumps and monitors must be capable of discharging foam and water while the vehicle is in motion (pump-and-roll capability).
