Why is back pressure needed during a turn in the Arrow?

• A. To increase speed
• B. To maintain altitude
• C. To reduce drag
• D. To stabilize roll

Answer: (B)

Back pressure during a turn in the Piper Arrow is essential to maintain altitude. When an aircraft is in a turn, the lift vector tilts along with the aircraft as it rolls. This means that some of the lift is now oriented horizontally, providing the necessary centripetal force for the turn, while the vertical component of lift is reduced. If no back pressure is applied, the aircraft would start to lose altitude because the overall lift decreases relative to the weight of the aircraft. By applying back pressure on the control yoke, the pilot increases the angle of attack, which in turn increases lift. This helps counteract the reduced vertical lift component during the turn, allowing the aircraft to maintain its altitude rather than descend. Maintaining altitude is crucial for safe flight operations, especially during maneuvers like turns that might otherwise alter the aircraft's flight path significantly. Other choices, such as increasing speed or reducing drag, do not directly relate to the need for back pressure in a turn, as the focus is primarily on maintaining altitude while still flying safely and efficiently. Stabilizing roll is managed primarily through aileron input rather than back pressure.
