Range in the Jonker JS1
As altitude increases, so does the jet engine’s efficiency. At an altitude of 2,000 metres, the maximum range increases to up to 240 km in saw-tooth mode, at 75,000 RPM to up to 211 km, and in horizontal flight at maximum performance to 150 km. From activation of the system to extending the jet engine to full thrust takes less than 40 seconds.
