Apressurized cabin, six seats, and a full-size air-stair door are unusual features for a piston-powered single-engine aircraft, but they are part of the package with the Piper Mirage (772.567.4361, www.piper.com). While the plane is designed primarily for utility and efficiency, Piper did not overlook comfort. The cabin features roomy leather-upholstered fold-down club seats, electric outlets for personal devices, reading lights, and an easily accessible interior baggage compartment. The cockpit is equipped with Garmin’s G1000 avionics suite, synthetic vision, ice protection, and a terrain warning system. The efficient Lycoming engine provides the Mirage with a range of 1,500 miles and a top speed of 245 mph. The starting price is about $1.1 million.
