What is one consequence of flying too close to the ground?

Flying too close to the ground can indeed result in increased lift due to ground effect, which is a phenomenon that occurs when an aircraft is in close proximity to the surface. As an aircraft approaches the ground, the airflow around the aircraft changes in such a way that it creates a cushion of air underneath, effectively increasing the lift produced by the wings. This is often beneficial during takeoff and landing phases, as it allows the aircraft to become airborne at lower speeds and reduces the stall speed.

The presence of ground effect can make it feel like the aircraft is performing better than it actually is, creating a false sense of security for pilots. It's important for pilots to be aware of this effect when flying close to the ground, as it can lead to an unexpected increase in lift when transitioning from ground to flight, which might affect their control and landing strategy. Understanding ground effect is essential for safe aircraft operation near the surface, as it helps pilots make informed decisions regarding altitude and speed during takeoff and landing.
