Here is the ideal way to transition young ag pilots into a modern, reliable turbine engine aircraft. Side-by-side seating provides significant advantages over tandem-seat trainers. The AT-504 provides natural and efficient conditions for communication and load sharing between the instructor and trainee. Delivering all the productivity of the AT-502B, the AT-504 meets the needs of a challenging ag business where a two-seat trainer must provide more than just performance; it must also make a profit.
