*JUST RELEASED* Pilatus PC-12 Owners: Enhance Your Investment!
Since its introduction in 1989, the Pilatus PC-12 has become the best-selling single engine turboprop. It has a reputation for reliability, operational flexibility, and performance. Pilatus continued to improve on its original design by increasing the useful load, engine performance, and even adding an integrated avionics package.
After analyzing the PC-12’s stock cowling, the engineers at American Aviation, Inc. identified areas that could be improved—specifically the ram air inlet and internal ducting. This analysis led to the design and manufacture of Speed Cowl™.The cutting-edge design combines a cowl inlet which maximizes the recovery of high-velocity ram air and internal ducting that is aerodynamic minimizing air separation and flow losses of the high-velocity air to the engine’s plenum. This results in higher available torque at the same ITT settings, which significantly improves the performance of the Pratt & Whitney PT6A-67 turbine engine.
Speed Cowl™has been flight tested in multiple flight configurations—climb, cruise at various altitudes, descent, with the inertial separator door open and closed—all at varied torque and ITT settings. During flight tests, the cruise true airspeed was shown to increase significantly in the flight levels. Also, time to climb above FL180 was noticeably reduced due to the available torque increase. Performance improvements will depend on altitude, outside air temperature, and ITT settings.
