It was a long flight and a relatively slow flight, but the trip in a modified King Air 350 from Orlando to Albuquerque likely broke a city-pair record (official acknowledgment is pending), thanks to the active winglets installed by Tamarack Aerospace.

On the way to the static display at Orlando Executive Airport for last October’s NBAA-BACE event, Tamarack made the trip nonstop, from Spokane International Airport in Washington to Orlando. Piloted by Jesse Nonnemacher, the Performance SmartWing-equipped King Air 350 flew 2,032.8 nm in 7 hours 46 minutes, averaging 240 ktas. Tailwinds averaging 20 knots helped propel the King Air and allowed for lower power settings to extend range. In addition to the Orlando-Albuquerque flight, Tamarack has also submitted the Spokane-Orlando city pair trip to the National Aeronautic Association and European Federation Aeronautique International for record recognition.
