The proof-of-concept prototype of the four-seat Stratos 714 single-engine jet has made its first flight.
Test pilot Dave Morss took the Stratos for a ten-minute first flight to check general stability and systems operation. The landing gear remained extended throughout the flight which was also limited to 128kt.
Stratos Aircraft said it will continue with a flight test programme to explore the aircraft’s flight envelope. It expects to reach a cruise speed of 400kt, a range of 1,500nm and a ceiling of 41,000ft.

“We invested the time and effort in the initial design and construction phases to assure that this proof of concept aircraft would ease the path to certification.
“After flight testing is complete, we will pursue a type certificate. We could shave off a considerable amount of certification time and start producing finished aircraft with additional investment, of course.”
Stratos is planning to launch the aircraft officially at EAA AirVenture Oshkosh 2017.
