PROXIMITY_AERODYNAMICS_LOG

When a drone flies within one wingspan's distance from the ground, it enters Ground Effect. The ground acts as a physical barrier that prevents air from escaping downward, creating a "cushion" of high-pressure air.

GROUND EFFECT DYNAMICS

REDUCED INDUCED DRAG

• Physics: The ground disrupts "Wingtip Vortices" (air swirling around the tip).
• Result: The wing becomes significantly more efficient.

THE "SLIPPERY" FEELING

• Experience: During landing, the drone may refuse to descend because it is "floating" on the air cushion.
• Risk: "Ballooning" back into the air if the pilot doesn't cut power correctly.
