Business aviation traffic in Europe dropped by 16 percent year-over-year in May with almost all categories of aircraft showing declines, according to Argus’s latest data for the Eurocontrol coverage area.

Turboprops led the declines, down 28.6 percent, driven in large part by a drop-off in multi-engine activity. Large aircraft followed with a 14.4 percent slide in activity overall as declines among the shorter-range aircraft in this segment offset gains in ultra-long-range aircraft flights. Light and midsize jets saw single-digit dips at 5.3 percent and 4 percent, respectively. However, super-midsize jets experienced a 4.8 percent uptick in year-over-year activity, Argus reported.

Despite the year-over-year results, business aviation did experience a seasonal uptick in May in Europe when compared with April. Flight activity overall was up 3.6 percent from April with light-jet flights jumping 22.2 percent from the month earlier. Very light jets, in particular, experienced a 30 percent increase. Large-jet activity also improved month-over-month in Europe by 15.9 percent, and midsize jets logged a 10.3 percent gains. However, while super-midsize jet flights were up year-over-year, they were down 14 percent from April.

Turboprop activity was down 16.7 percent as multi-engine activity plunged 22.5 percent, offsetting modest gains in single-engine turboprop flights.
