The exhaust coming out of aircraft engines looks pretty dangerous, generating huge amounts of thrust and pushing back tons of hot air. Vortex size is also affected by proximity to the ground. If youre flying low enough to be in ground effect, the vortex isnt able to fully develop. This phenomenon is called Ground Effect.

The prototype lifted off, hovered and flew at a speed of 40 knots before landing. Once stable in ground effect, the pilot shut down EPU1 (left-side outboard) to simulate the performance in the case of an engine failure. The pilot then increased acceleration with a target of seven knots ground speed.

Thrust : The force generated by the engine that propels the aircraft forward. Pilots must counteract the additional drag with more thrust to maintain altitude. The stall warning horn sounds at least 5 knots above the actual stall speed. Gradually reduce thrust from cruise power. Don’t go all the way back to idle.

We routinely taxi at 1200 rpm due to the low spray…[we] can cruise at 10 knots” in displacement mode, something a Goose can’t do. Early on a speed restriction of 130 knots was applied as a flutter issue. This was resolved on the kit version and led to cruising at 50% power and 120 knots, which proved to be the Gweduck’s sweet spot.
