History
The C90GTx belongs to a line that began with the King Air Model 90. Beechcraft announced that aircraft in July 1963, offering turboprop power in place of the piston engines of the Queen Air, and the first example flew on 24 January 1964 on a pair of PT6A-6 engines from Pratt & Whitney Canada. Over the following five decades the C90 passed through many variants.
Two of those steps led directly to the GTx. The 2005 C90GT gained PT6A-135A engines with more power, and in 2007 the C90GTi introduced a ProLine 21 flight deck from Rockwell Collins. The C90GTx arrived in 2010 with winglets and a higher maximum take-off weight, so operators could fill the tanks and still carry a useful payload. Each engine is rated at 550 shaft horsepower, below its 750 hp capability, and production continued until 2021.
The engine has a long record behind it. By 2016, PT6A engines had flown over 400 million hours, and only one shut down in flight for every 651,126 hours of operation. That reliability, built up over more than 50 years, helped the King Air 90 series become a fixture of business aviation worldwide.

FAQ
Is the King Air C90GTx able to land at Gstaad and similar short alpine strips?
Yes. Short-field performance is one of its strengths, with a take-off distance of 605 m, so it can use regional airports that many jets cannot. At Gstaad-Saanen the 1,400 m runway is more than enough, although altitude and mountain terrain affect performance and crews take both into account. That makes it a practical way to land close to alpine resorts and other remote destinations.
How does the C90GTx compare with the older King Air F90?
The F90 arrived in the late 1970s as a crossover, combining the C90's fuselage with the B200's wings and T-tail. It was a clever design for its time, but today its avionics look old and its performance is less efficient. The C90GTx, launched in 2010, has PT6A-135A engines, composite winglets, Pro Line Fusion avionics and a quieter cabin, and it climbs better, uses less fuel and is more comfortable for passengers.
What trips is the King Air C90GTx typically used for?
It is mostly used for regional flights where reaching a smaller airport matters. In Europe it links cities such as Munich, Milan or Geneva with nearby alpine airfields like Sion and Saanen. In the United States it flies regional routes such as Houston to Dallas or Nashville to Chicago, often into secondary airports that jets cannot use.
What range does the C90GTx have?
With IFR reserves it covers 903 nm (1,672 km), and the ferry range is 1,260 nm. Passenger load, baggage and weather all change the figure, but routes such as London to Ibiza or New York to Chicago are within reach without refuelling. That makes it best suited to short and medium sectors.
