The Beechcraft King Air 300, a twin-turboprop aircraft with a capacity of up to 11 passengers, features Pratt and Whitney PT6A-60A engines for improved performance. A lightweight version (300LW) was introduced due to regulatory restrictions in some countries, with a maximum takeoff weight (MTOW) of 12,500 lbs.
The King Air 300 has been used by the Federal Aviation Administration (FAA) and other countries for navaid calibration. The 350i model, introduced in 2008, features enhanced passenger comfort and cabin upgrades. Initially marketed as the Super King Air, the Model 300 is a slightly stretched version of the Model 200. The prototype flew in September 1983, with deliveries beginning the following year. The Model 300's MTOW is 14,000 lbs (6,400 kg).
According to GlobalAir.com, “The King Air 300 was developed by straightening the edges and redesigning the cowling of the Model 200 airframe. Pratt and Whitney PT6A-60A engines were added for improved performance and power. As a result of this engine upgrade, maximum takeoff weight increased to 14,000 pounds, range extended to 1,500 miles, and maximum cruise speed increased to 320 knots.”
