Compare the fixed costs, variable cost, and performance of Beechcraft King Air C90GTi to over 500 jets, turboprops, helicopters and piston aircraft, with accurate data from Conklin & de Decker.
The King Air C90GTi is a King Air C90B, with a Collins Pro Line 21 avionics suite and more powerful Pratt & Whitney Canada PT6A-135 engines. This gives the aircraft better climb and cruise performance compared to earlier C90 models.
The Beechcraft King Air series has its roots in the Twin Bonanza of 1951. That aircraft model was enlarged and re-engined to become the Model 65 Queen Air. The Queen Air design changed to incorporate a swept tail and pressurization. With the addition of Pratt & Whitney turboprop engines, the Queen Air became the Model 90 King Air.
The Model 90s have seen their way through the alphabet with the 90, A90, B90, C90, D90 (not built), E90, F90 and H90 (also not built). The C90 models were the most popular. The Model 90 was first certificated in 1959 and is still being produced over 40 years later as the C90B and C90GT. Two Pratt & Whitney PT6A-21 engines power the C90, -1, A, B and SE. Two Pratt and Whitney PT6A-135s power the C90GT. As the C90 has progressed, there have been evolutionary changes made in avionics and systems to keep the aircraft fresh. The C90SE is a “special edition” C90 with fewer options, more basic avionics and a reduced base price over the C90B—essentially a price leader.
The King Air 90s seat five and have aft-lavatories, a nice feature in a small turboprop. The cabin is not round and is shaped more like a loaf of bread, which gives passengers more shoulder room.
