A comprehensive guide for buyer’s and investor’s of the Beechcraft King Air 250 range of versatile turboprop business jets.



A rugged aircraft capable of flying into the smallest and most remote airfields, with a relatively comfortable cabin.


Relatively more expensive to own and operate in compared to other turboprops.



The Beechcraft King Air 250 has a maximum range of 1,720nm* – far enough to fly between Houston and Seattle or London and Istanbul (*manufacturer quoted ferry range).

Two Pratt & Whitney PT6A-52 turboprop engines deliver a maximum speed of 357mph – making the King Air 250 relatively fast for a turboprop.

The King Air 250 is built for rugged and remote missions. Its landing gear allows the aircraft to utilise unimproved airstrips – meaning passengers can land close to their final destinations. This makes the King Air 250 a great choice for businesses with interests in natural resources.

Due to its typical mission profile, the King Air 250 is likely to fly into airports located at high altitude, with hot weather. And nothing reduces aircraft performance more than heat and altitude – especially when they are combined.

In the King Air 250, the PT6A-52 engines are rated to ISA+37 – meaning it can still perform in hot and high conditions – allowing passengers to fly into or from airports such as Denver, Mexico City or La Paz, even at the height of summer.

In the cockpit, the 250 features a Rockwell Collins Pro Line Fusion flight deck – a system geared towards single pilot operations. This need for only one pilot reduces crew costs and also opens up an additional seat in the cockpit for a passenger.


With a cabin height of 4ft 9in and width of 4ft 6in, the King Air 250 has one of the largest cabins in the turboprop market. This is mostly due to the King Air family’s ‘square-oval’ fuselage shape – making the cabin surprisingly spacious.

The aircraft can seat eight passengers in the cabin. The standard configuration features double club seating behind two regular seats – all of which swivel and recline. There is also the option to add a belted lavatory and another seat at the rear of the aircraft.

The interior features a refreshment centre with two fridges, two hot-drink dispensers and drawers.

The cabin also includes WiFi connectivity, two foldaway worktables and power outlets.

One of the most impressive features of the 250 is the quietness of the cabin. Vibration dampeners reduce the level of noise from the turboprop engines, allowing for a more peaceful journey for passengers – making the cabin a great working environment.


Between 2011 and May 2018, 197 King Air 250s had been produced. Unsurprisingly, almost two thirds of the active fleet are based in North America. As of May 2018, there were 11 aircraft for sale – representing 5.67% of the active fleet.
