Just noticed that Deltahawk published (yesterday) airspeed and fuel flow data for their DH160-equiped Velocity flying at 11,500 altitude. To me, as a non-expert in engines, that data seems just amazing: > ... at 145 KTAS and 11,500 feet MSL the DeltaHawk is burning only 3.81 > GPH or more than 36% LESS fuel than the IO-360 ... Grigore
