Take your basic family sedan, stick a hot motor under the hood and give it with sporty-sounding initials like RT or SS and voilà: You get GT car. A similar thought occurred to some folks at what is now Hawker Beechcraft regarding the venerable six- to seven-passenger 90-series King Air twin-turboprop. What they came up with was the C90GT, which boasted more powerful engines with lower operating temperatures that improved performance-35 knots more speed and faster climb times.

Cruising speed at 267 knots and a cabin big enough for six to seven adults sitting in comfortable, adult-sized seats and pressurized baggage space capacious enough for several of Zsa-Zsa’s full-size roll-ons, hat bags and many sets of golf clubs. But the feature makes this airplane stand out among the rest the big cabin and its large oval windows. You enter up the aft airstair door. The netted baggage hold and belted potty sea are conveniently on your right, a single-place side-facing kibitzer faces the door, and to the left is a club-four grouping of facing slide-swivel and reclining executive seats that share two large pull-out sidewall tables big enough for large laptops.

Key enhancements from its predecessort, the C90GT, include an increase in gross weight and the addition of composite winglets to improve climb performance and further increase fuel efficiency. The C90GTx seats up to seven passengers. It includes an in-flight accessible, heated, and pressurized baggage storage area along with a private aft lavatory as standard.

The gross weight has doubled the full-fuel payload. New composite winglets improve the climb rate while increasing fuel efficiency. The aircraft can cruise at 270 knots true airspeed at 20,000 feet, powered by two Pratt and Whitney Canada PT6A-135A engines.
