Piper Matrix When airplane makers add a product to their lineup, they need to bring something new to the mix. In the case of the Piper Matrix, that new ingredient is a hearty helping of value. The Matrix, an offshoot of the popular Mirage, is a high-performance, retractable-gear, true cabin-class single with a difference: It is unpressurized. This change, along with some other value-minded modifications, lets Piper keep the price of the airplane low, less than $850,000 very nicely equipped. Just as Piper hoped, that price point has proven alluring to many pilots who are happy to be flying at non-oxygen altitudes (or in the teens with supplemental oxygen) but who want a real cabin-class experience for their passengers. The Matrix moves along at better than 200 knots at altitudes pilots typically fly, and it does it with the full-featured flat-panel Avidyne Entegra avionics package, the S-Tec 55X autopilot and proven known-icing equipment. Most importantly, the Matrix does it with an airstair door in back, one that leads to an attractive and comfortable club-seating area. For finding a way to bring this experience to a new class of pilots, we make the Piper Matrix a Flying Editors' Choice for 2008.
