Innovative Solutions & Support ThrustSense Autothrottles for PC-12s and King Airs

Geoff Hedrick, the late founder of Innovative Solutions & Support (IS&S), used to fly a Pilatus PC-12 for business and personal travel. So it was natural that Hedrick would end up working closely with Pilatus Aircraft on integrating into the PC-12 the expertise developed by his company for commercial platforms like the Boeing 757 and 767. IS&S introduced the ThrustSense autothrottle to the series as an aftermarket add-on in 2017, and it became standard on the PC-12 NGX in 2019, paired with the FADEC-equipped Pratt & Whitney PT6E-67XP. Now, more than 30 PC-12s have been retrofitted with the system, according to Tom Grunbeck, director of autothrottle products for IS&S.
