Question: 1 / 550

What effect does a fixed slot have on a wing?

Increases stall speed

Delays stall

A fixed slot on a wing plays a crucial role in enhancing the aerodynamic performance, particularly during low-speed flight. By allowing a controlled flow of air over the wing's surface, a fixed slot helps to delay the onset of stall. This occurs because the slot maintains airflow attachment over the wing longer than it would without the slot, thereby preventing the early separation of the boundary layer.

This aerodynamic modification is especially beneficial for aircraft that operate in slow speed regimes, where maintaining lift is critical. By delaying stall, the aircraft can operate safely at lower speeds, which is essential during takeoff and landing phases.

While the other options mention aspects that are influenced by airflow characteristics around the wing, such as stall speed, lift, and drag, the particular emphasis of fixed slots lies primarily in their ability to delay stall, enhancing overall safety and performance.
