What is the main purpose of an elevator in an aircraft?

• A. To increase the speed of the aircraft
• B. To control the pitch of the aircraft
• C. To assist in banking the aircraft
• D. To stabilize the aircraft during turbulence

Answer: (B)

The main purpose of an elevator in an aircraft is to control the pitch. The elevator is a control surface located on the tail of the aircraft, and it plays a crucial role in adjusting the angle of the aircraft's nose relative to the horizon. When the pilot moves the yoke or control stick forward or backward, the elevator deflects up or down, causing the tail of the aircraft to move in the opposite direction. When the elevator is deflected upwards, the tail goes down, which causes the nose to pitch up, increasing the angle of attack and enabling the aircraft to climb or gain altitude. Conversely, if the elevator is deflected downwards, the tail rises, and the nose pitches down, which allows the aircraft to descend. This mechanism of controlling pitch is vital for flight maneuvers and maintaining proper altitude. The elevator's specific function in regulating pitch distinguishes it from other control surfaces and flight dynamics, making comprehension of its role essential for understanding fundamental aircraft operations.
