Flight Design conducted the first flight of the C4 prototype in Germany last Thursday, officially launching the test phase for the first general aviation airplane scheduled to be certified under new rules designed to improve safety and bring down the costs of future light aircraft.
Flight Design conducted the first flight at its headquarters in southern Germany on April 9, taking the C4 up for a 60-minute test hop ahead of the Aero Friedrichshafen show in Germany this week, flight test engineer Robert Adam told AvWeb.
