Business-aviation flying in North America accelerated again last month, climbing 2.8 percent from a year ago, and is projected to rise by a more modest 0.8 percent this month, according to the latest TraqPak data from aviation services group Argus International.

The Part 135 charter segment came out strong last month, with activity up 5.7 percent year-over-year. Part 91 flying logged a 2-percent gain over April 2014, while fractional activity trended slightly negative, falling 1 percent. Activity by aircraft category was positive across the board last month, led by large-cabin jets with a 6percent gain. Trailing closely behind were turboprops, up 4.7 percent from a year ago, while light jets saw a 2percent uptick. Midsize jets increased ever so slighty; this segment was just 34 flights above April 2014 activity levels.

The fractional segment saw both the largest gain and loss in individual results, with fractional turboprop activity climbing 16.1 percent and fractional midsize-jet flying skidding by 5.1 percent. Part 135 large-cabin jets saw the only other double-digit increase, at 11.8 percent.
