Air Taxi Prototype Crash at Cotswold Airport

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.

How to Make a Perfect Soft Field Landing Every Time

Pilot Institute

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.

How to Master Slow Flight (Step-By-Step)

Pilot Institute

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? Why does this happen?

Invisible Trap Kills Glider Pilot – How To Avoid Microbursts

Chess In the Air

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. This is consistent with Rick’s report, which referenced 9 knots of wind.

What NTSB Reports Say About Impossible Turns and Angle of Attack

Air Facts

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). No math required.
