After first demoing the concept in 2015, Innovation Solutions and Support (IS&S) announced they're one step closer to bringing an autothrottle to the single-engine turbine PC-12. IS&S says the FAA has granted the Supplemental Type Certificate for their integrated PC-12 flight deck and that new avionics package includes compatibility with the IS&S autothrottle system. The FAA says, if approved, the IS&S PT6 autothrottle will be the first certified autothrottle system in a turboprop airplane. The FAA released proposed special certification conditions for the autothrottle in a regulatory filing Friday, since there is no existing basis for certifying an autothrottle in a Part 23 airplane.
