Wingtip Vortices and Wake Turbulence

Pilot Institute

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 lateral movement takes place at a speed of about two or three knots. As at higher altitudes, the vortex movement near the ground is affected by crosswinds.

Comprehensive List of Trainer Aircraft for Student Aviators

Pilot's Life Blog

With a cruise speed of around 162 knots and a range near 700 nautical miles, the Seminole provides performance without overwhelming complexity. On the other hand, the Piper PA-28 series (like the Cherokee or Archer) offers a low-wing configuration, which means slightly different ground effect and flare behavior.

Accident Briefs—July 2025

Plane and Pilot

A witness reported that they saw the airplane lift off from the runway and remain in ground effect until it crossed the departure end of the runway. After arriving at the destination airstrip the student entered left downwind for Runway 13, resulting in a right quartering tailwind of about 5 knots.

REGENT to launch defense division, autonomous wing-in-ground military vehicle 

Aerotime

It will also be autonomous and capable of delivering payloads of up to 50 lbs (22kgs) at speeds of 70 knots (80 mph / 128.7. Ground-in-wing vehicles (also called ground-effect-vehicles) use a physical phenomenon that enhances the aerodynamic performance of craft flying at very low altitude over bodies of water.

Quiz: Understanding Aircraft Performance

Flight Training Central

What is ground effect? 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? 187 knots 162 knots 165 knots Correct! It reduces climb performance. a higher-than-normal angle of attack.

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. 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.

Tow Plane Flies Too Slow – Glider Heavy with Water Ballast

Chess In the Air

However, perhaps the safest response for everyone involved would have been the following: Rather than trying to climb with the tow plane, I should have stayed in ground effect while communicating the request for a greater airspeed. Staying in ground effect protects the glider from a stall because of lower induced drag.
