This meant the airplane, if were to carry anything, had to be built from very light materials incapable of providing support for a wing long enough to generate the needed lift. The bi-wing design allows two shorter wings to be braced against one another with a series of struts and wires providing the strength and lifting surface required.

What is likely to occur if you lift off the runway before reaching rotation speed due to ground effect? Aileron down on the upwind wing Aileron up on the upwind wing Aileron up on the downwind wing Correct! Inability to climb Increase in stability Decrease in thrust required to maintain flight Correct!

Fear of Landing

The prototype lifted off, hovered and flew at a speed of 40 knots before landing. The forward five-bladed propellers tilt in an angle range of 0° (straight ahead) to 100° (slightly past vertically upwards), allowing the aircraft to shift between vertical lift and forward propulsion. G-EVTL lifted off with all EPUs operating.

Hold this extra power as you enter ground effect. Low-wing aircraft perform better in ground effect because of the wing’s proximity to the ground. The sudden loss of lift can cause the wheels to dig into the ground. Here is where your aircraft’s configuration comes into play.

Lift : The aerodynamic force generated due to airflow over the wings. The aircraft’s deceleration reduces the airflow over the wings, which reduces lift. When the lift force is less than the force of gravity, the aircraft descends. So, how do we increase lift to maintain altitude? The gear adds lots of drag but zero lift.

An incomplete summary description of FASF is whether the airplane made it out of ground effect. To get the extra lift required for the turns, I had to dive to get extra airspeed so that the plane could turn at that same AOA. That phenomenon is best named Failure to Achieve Sustained Flight (FASF).

There were some patches of moderate lift and sink as would be expected on a normal summer soaring day. Shmulik flew quite fast at ground speeds between 100 and 130 kt, carrying a lot of extra energy. Sometimes you fly through virga and you can even find yourself in lift. I should have never been below 80 kts in the pattern.
