The Air Tractor AT-504 is a spray plane and trainer that's an excellent platform for aerial application instruction. Side-by-side cockpit seating lets experienced pilots effectively train new turboprop pilots. Both instructor and trainee each have complete flight controls and virtually the same cockpit view and flight perspective. Equipped with a Pratt & Whitney PT6-34AG engine, the AT-504 has working speeds equal to the AT-502B. Payload capacity is 485 gallons. Novice turboprop pilots experience similar flight performance when they move from the AT-504 to the AT-502B or other similar size turboprop ag planes. The AT-504 performs beautifully and is fun to fly. And like the rest of the Air Tractor line, it can be a real money maker.
