Which instrument helps pilots during turns?

The Turn Coordinator is an essential instrument for pilots during turns as it provides a visual indication of the aircraft's rate of turn. It typically features a rotating dial that reflects the aircraft’s yaw and helps the pilot maintain a standard rate of turn, which is usually 3 degrees per second. By utilizing this instrument, pilots can ensure that their turns are smooth and coordinated, preventing unintentional skids or slips that could arise from an imbalanced turn.

The Turn Coordinator also has a feature that indicates whether the turn is coordinated, providing a crucial tool for pilots to maintain proper control of the aircraft throughout the maneuver. This is especially important when flying in visual flight rules (VFR) conditions or while conducting instrument approaches.

Other instruments listed, while valuable for various flight operations, do not specifically aid in managing turns. For example, a medical altimeter has no relevance to aircraft maneuvering, and both the vertical speed indicator and heading indicator serve different functions related to altitude change and directional navigation, respectively.
