The AT-802 series is the world’s largest airplane single-engine, and its popularity reflects the tendency of turbine engines make more capacity. Whether used for reforestation of forests, and for spraying large areas of cotton, or the use of dispersants for oil spills, the plane has enough features for productivity and work very efficiently.
The AT-802A is a cantilever low-wing aircraft, all-metal construction monoplane. It is specifically designed for extinguishing forest fires and is equipped with a single cabin. The avionics compliant IFR instrument flight and air conditioning / heating electronics and autopilot.
The power plant consists of an engine turboprop Pratt & Whitney brand PT6A-67AG model of eshp 1.430. This engine is highly reliable and tailored to the type of flight requirements that require fire for power with high ambient temperatures, ease of maintenance, low noise emission, etc … The propeller used is a 5-blade Hartzell high performance and constant speed reversible step.
The version used by Avialsa T-35, SL fuel tanks installed high-capacity, 380 gallons (1,438 liters), giving a great flight range (5 hours) or to operate from remote forest tracks or to make long flights forest monitoring.
The high maneuverability of the AT-802A, coupled with the versatility of downloads that you download system provides computerized and programmable in terms of needs, make this plane get over the performance of many aircraft load capacity.
Moreover, the ability to operate from unprepared runways possible, close to the fire, help greatly to reduce the time of discharge cycles.
Another possibility for the AT-802A is to carry a separate tank for foam concentrate by means of a computer-controlled injector system, added to the water tank foam optimal proportion to the type of fire involved. This system is particularly suitable for forest patrol flights as if they do not detect any fire, the sparkling wine is returned to the base to be used on another occasion.
The AT-802A has a feature that sets it apart from any other firefighting aircraft and is that you can land with maximum takeoff load (7258 kg), ie that can land with a load in the hopper 3990 kg thanks to its extremely rugged landing gear and braking system, sized for this purpose. This ability is recognized by the aeronautical authorities and included in the Type Certificate.
