What is ground effect? What effect does high density altitude have on aircraft performance? What is the headwind component for a landing on Runway 18 if the tower reports the wind as 215° at 30 knots? Ground effect is most likely to result in which problem? It increases takeoff performance.

This is consistent with Rick’s report, which referenced 9 knots of wind. At this point his ground speed was 81 kts, which – in still air – would reflect a normal pattern speed of approx. 65 kts IAS given the high density altitude. He may have expected an easy and uneventful landing.

An incomplete summary description of FASF is whether the airplane made it out of ground effect. That phenomenon is best named Failure to Achieve Sustained Flight (FASF). This is more theoretical than practical for visual AOA, but can affect some proposals such as a general aviation stick shaker. No math required.

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.
