Final answer:
Ground effect is a phenomenon in which an airplane experiences increased lift and reduced drag when flying close to the ground. It allows for more efficient and stable takeoffs and landings. Understanding ground effects is important for pilots to ensure safe and successful flights.
Step-by-step explanation:
When an airplane is near the ground, it experiences what is called the ground effect. Ground effect occurs because the air pressure underneath the wings increases while flying close to the ground, resulting in a cushioning effect. This effect reduces drag and increases lift, making the aircraft more efficient and stable during takeoff and landing.
For example, when an airplane is in ground effect during takeoff, it requires less power from the engines to achieve and maintain lift. This is why during takeoff, the airplane may seem to accelerate more rapidly.
Ground effect is an important consideration for pilots, especially during takeoff and landing, as it can affect the aircraft's performance and stability.
