What is the function of the inclinometer in flight instruments?

The inclinometer is a flight instrument primarily used to indicate the rate-of-turn of an aircraft. It provides essential information to pilots regarding the aircraft's orientation in relation to the horizon during a turn, helping to ensure that the maneuver is executed safely and effectively. The inclinometer works in conjunction with the attitude indicator to give a complete picture of the aircraft's position, aiding in maintaining control and situational awareness, particularly in conditions where visual references might be limited.

In flight operations, understanding the rate of turn is vital for navigation and maintaining the desired flight path. By accurately displaying this information, the inclinometer assists pilots in executing coordinated turns without excessive banking or unintentional loss of altitude. This is particularly important in training and real-world flying, where the dynamics of turns can significantly affect flight performance and safety.
