King Air E90
Following the C90, Beechcraft moved onto the King Air E90 after a D90 prototype was abandoned. The E90 is simply a more powerful version of the C90. The two models were produced in parallel, with the E90’s major difference being upgraded PT6A-28 engines that give the aircraft a further range, faster cruise speed and better takeoff performance. It also has a slightly modified wing.
The King Air E90 has a normal cruise speed of 228 knots, a range of 1,290 nautical miles, a climb rate of 1,870 feet per minute, and requires 4,220 feet of runway to takeoff and 2,737 feet to land.
King Air F90
Next, Beechcraft began manufacturing the King Air F90, as well as its follow-up F90-1 model. The F90’s fuselage is identical to the E90, but the F90 comes equipped with the T-tail and wing featured on the King Air 200. It also comes equipped with upgraded PT6A-135 engines. The upgrade gives the F90 a faster climb rate and faster cruise speed compared to its predecessor. The F90-1 was given further upgraded PT6A-135A engines, giving it an even faster climb rate and cruise speed than the original F90.
The F90 has a normal cruise speed of 245 knots, a range of 1,235 nautical miles, a climb rate of 2,380 feet per minute, and requires 5,265 feet of runway to takeoff and 4,041 feet to land. The F90-1 has a normal cruise speed of 260 knots and a climb rate of 2,455 feet per minute, while its other specs are identical to the F90.
King Air H90
After building a prototype of a model G90 fitted with the Garrett TPE-331 engines that never gained traction, Beechcraft began working on a military training version of the C90, called the H90. The H90 was used as a pilot trainer for the United States Navy, fitted with PT6A-34B engines. The military dubbed this model the T-44A Pegasus, and used it primarily to train pilots to fly multi-engine aircraft.
The King Air H90 has an airspeed maximum of 245 knots and a range of 1,300 nautical miles, based on the little information available on the aircraft.
