The King Air line is a family of turboprop aircraft that have been in production since 1964. It was the first aircraft in its class and has outsold all of its turboprop competitors combined over the years.

The King Air 90 has many different variants that were developed and sold over the years. Most of the differences were engine upgrades along with avionics improvements more recently. The original 90 has PT6A-6 engines made by Pratt & Whitney Canada. These tested and proven engines are trusted workhorses in aviation circles. In 1966 production switched to the A90 model with a PT6A-20 engine. Just a few years later further improvements made the new designation of B90 models.

In 1971 the C90 model was introduced with an increased wingspan and increased vehicle takeoff weight. Along with engines upgraded to PT6A-20A. PT6A-28 engines were added for the E90 model .

In 2005 Beechcraft introduced the C90GT with new PT6A-135As that deliver 550 shp. The engines increased both cruise speed and rate of climb due to lower operating temperatures. With a 316mph cruise speed the C90GT is competitive with very light jets for short to medium range flights all with a larger, more comfortable cabin space for the passengers. The operating costs are also cheaper than competitive very light jets leading to more affordable air charter rates.

In 2007 C90GTi’s were introduced with upgraded Rockwell Collins Proline 21 avionics for an even better experience for pilots.
