RAYTHEON AIRCRAFT COMPANY B300
Everything here is true of every aircraft of the type, not of any one aircraft.
The King Air 350, designated B300, is the largest of the line: a stretched B200 with winglets, 1,050 shp engines and a cabin long enough for nine passengers in club seating with a proper lavatory. It cruises at 312 knots with 1,800 nautical miles of range and does most of what a light jet does while using runways a jet cannot, which is why corporate flight departments, fractional operators and government agencies buy them in quantity. Introduced in 1990, the aeroplane kept its engines and weights throughout; the 2004 model added wing-locker baggage compartments in the nacelles and the Collins Pro Line 21 flight deck announced in late 2003, and from December 2009 it was delivered as the 350i with a redesigned, quieter cabin. So a 1998 aircraft has conventional instruments and no lockers, and a 2006 the Pro Line 21.
The important difference from a B200 is regulatory as much as physical: at 15,000 lb maximum takeoff weight the King Air 350 requires a BE-300 type rating, where the 12,500 lb B200 does not. That is a materially higher training and currency burden and it changes who can legally fly the aeroplane. The operating costs rise in proportion — two PT6A-60A engines, roughly 110 to 120 gallons an hour, a cabin-class annual, and two pilots in nearly all operations. It is a lot of aeroplane and it is priced and crewed accordingly.

- Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories.
