About the Fire Boss

Configuration

1. WATER & FOAM TANKS

820 USG (3,104L) water capacity plus up to 78 USG (296 L) foam capacity

2. Safe Instrumentation

The scooping control panel is located so the pilot’s attention is maintained at windscreen level during critical operation phases.

3. Pratt & Whitney 1,600 hp PT6A-67F Engine

The turbine PT6A-67F boasts legendary reliability, fast start-up with no warm-up period, 150 knots cruise speed, and exceptional performance with the ability to quickly climb to high mountain elevations and execute aggressive down-slope drops.

4. The Airframe

A rugged aircraft built with confined area operations and maneuverability in mind. The AT-802F has been purpose built and FAA-certificated for aerial firefighting. It can be refitted with conventional landing gear in the off season to perform additional missions.

Single-Seat & Two-Seat Trainer Models Available

5. FIRE GATE

The fire gate controls the rate and volume of water release. It allows the pilot to perform accurate salvo or string drops.

Fire gate options include:

Air Tractor Gen II FRDS (Factory Standard)
Hydramax Fire Gate
Hatfield Fire Gate

Wipline 10000 Amphibious Floats

6. Retractable Landing Gear

Rugged amphibious versatility for runway, gravel or water take-offs and landings

7. High Efficiency water Scoops

Simple, easy to maintain, and effective. The scoops are designed to be safely deployed at landing speeds

8. WATER TRANSFER TUBE

Moves the scooped water up the float pylon and into the fuselage holding tank.

9. Removable Foam Tanks

Optional removable tanks slip inside the floats and add up to 60 USG (226 L) foam capacity to the 18 USG (69 L) fuselage foam tanks

Water Delivery Based on Distance From WAter Source

Distance between fire and water source (in US Miles)	Average turnaround time (in Minutes)	Water delivered to fire per hour (in US Gallons)
1	3	14,000
5	4	10,500
10	6	7,000
15	9	4,666
20	11	3,818

This chart shows the gallons of water the Fire Boss is able to deliver to a fire based on the distance between the fire and the nearest scoopable water source. It assumes that the Fire Boss has 2.5 hours of fuel endurance including a 30-minute reserve (U.S. Fire Agency Minimum Requirement). It also assumes scooping loads begin at approximately 600 gallons and approach 820 gallons as fuel burns and that no foam is carried onboard.
