What is the primary purpose of a Turn Coordinator in an aircraft?

The primary purpose of a Turn Coordinator in an aircraft is to indicate the rate of turn and coordination. This instrument provides critical information about the aircraft's bank angle and whether the turn is being executed properly. By displaying the rate of turn in degrees per second, pilots can maintain a standard rate turn, which is essential for managing flight path and monitoring aircraft performance during turns.

Moreover, the Turn Coordinator also assists in ensuring that the turn is coordinated, which prevents uncoordinated flight conditions, such as skidding or sliding, that could lead to loss of control. Understanding and using the Turn Coordinator effectively is vital for maintaining safe navigation, especially in conditions where visual references may be limited.
