I remember when I was training for my PPL, my flight instructor told me that sometimes on a very windy day you can seemingly “hover” in mid-air (especially with a very light airplane). He also told me stories about planes lifting of the ground while parked if it’s windy enough. It is simply all about airspeed over the wings. Well, some crazy daredevils off the coast Portugal really put the theories of “windspeed over wings” to the test!
Check out this video of a small STOL Aeroprakt Foxbat A22 plane landing on a moving ship at sea (with no arrestor wire like on aircraft carriers). The landing strip (i.e., deck) was only 60 meters long, and they nail a pretty amazing landing….and then proceed to takeoff as well! According to the video folks, the ship was sailing at 9 knots speed over ground, and true windspeed was 14 knots, combined just under the full flap stall speed of the airplane.
