The King Air® C90GTx is a whole new world of flying that offers the impressive King Air qualities of performance combined with comfort. This versatile workhorse has great range and payload due to its features like composite winglets, swept-blade propellers, and dual aft strakes. The King Air C90GTx is a favorite aircraft.
The Beechcraft King Air C90GTx entered service in 2010, doubling payload capability and allowing the aircraft to carry more fuel under all loading scenarios and to fly further. Extended range and improved efficiency of the King Air C90GTx are essentially down to its innovative composite winglets, which reduce drag and allow faster climb and lower fuel burn.
In March 2019, there were 168 King Air C90GTx turboprops in operation, 165 of which were wholly-owned. North America was home to the largest King Air C90GTx fleet percentage (42%), followed by South America (32%), then Europe and Asia (10% each) — accounting for a combined 94% of the fleet.
A maximum range of 1,260nm allows passengers to fly from Houston to New York, Los Angeles to Kansas City or London to Saint Petersburg.
Two Pratt and Whitney PT6A-135A turboprop engines power the C90GTx to a maximum cruise speed of 313mph – making it one of the slower business turboprop aircraft available. But speed is not the point of the C90GTx.
The C90GTx is a rugged aircraft that is capable of taking-off in just 1,984ft. Its rugged landing gear means it can put down on unimproved airstrips – allowing passengers to land closer to their final destination. This is where the C90GTx really comes into its own.
A maximum altitude of 30,000ft allows the aircraft to fly above most bad weather, and also improves fuel efficiency by being able to fly in thinner air. This cruise altitude is good for a turboprop – but jet-powered aircraft can fly higher.
The C90GTx can seat six passengers in its ‘square-oval’ cabin shape which, Beechcraft claims, creates more headroom and shoulder space. Even so, the cabin has a height of just 4ft 9in and width of 4ft 6in. But you do not buy a turboprop aircraft to have a large cabin.
Four of the reclining seats are set out in a double-club configuration. In the aft of aircraft there is also a belted lavatory and an optional side-facing additional seat. The C90GTx is single-pilot operated aircraft, meaning another passenger can sit in the cockpit.
The cabin includes a lavatory, an ice drawer, two heated drinks dispensers, drawers, plug sockets, optional WiFi and dimmable window shades.
The cabin is a quiet environment due to 26 tuned vibration absorbers, which help minimise noise entering the cabin – making it an environment conducive to working.
A useful load weight of 3,280lb/1,488kg allows for ample amounts of luggage to be carried alongside passengers. However, other turboprops such as the PC-12NG are able to carry far greater payloads.
Passenger and baggage amounts can greatly effect the performance of an aircraft since minimum runway lengths, range and speed are all effected by its weight.
Typical passenger configuration is the typical number of passengers the jet is configured to accommodate 5 passengers, however each jet will have a custom configuration to accommodate an owners specific needs and will therefore vary.
Internal baggage capacity is the amount of available baggage which can be stowed inside the aircraft where there will be pressurization and temperature control.
External baggage capacity is the amount of baggage space accessed from outside the aircraft and may not have pressurization or temperature control.
Total number of bags is the total number of bags, using an average 5 cubic feet per bags plus 2 cubic feet of space between bags (unusable space) that you could expect to fit in the aircraft.
Typical passenger configuration: 5 pax
Internal baggage capacity: 48 cubic feet
External baggage capacity: 0 cubic feet
Total number of bags: 7 bags
Cruise speeds vary greatly during the course of a flight, during climb, cruise and descent. In addition, there is a speed limit of 250 knots below 10,000 feet which will impact average speed for shorter flights greater than longer flights.
Maximum cruise is the speed the aircraft can fly at its optimal altitude where the air is thinner.
Average cruise is calculated by taking an average trip length and takes into account the climb, speed limit, cruise and descent speeds.
Long range cruise is the speed required to attain the maximum range.
Maximum Cruise: 307 mph
Average Cruise: 307 mph
Long Range Cruise: 228 mph
