	A rate gyro is a gyroscope that is used to measure the rate of movement about a specific axis. The most common use of a rate gyroscope is the Turn and Bank (T&B)indicator used in aircraft. The T&B indicates to the pilot the rate of turn around the yaw axis of the aircraft, when used in conjunction with the inclinometer that is mounted on the face of the instrument the pilot can maintain a specific rate of turn for the aircraft while also maintaining a force of 1 g on his airframe. This is useful for a number of reasons for example: If all other navigation devices have become in-op the pilot can navigate by time and direction. (Turn left for 1 minute at a standard rate of turn as indicated on the T&B) Also when a force of 1 g is maintained the passengers do not feel the aircraft turn. This maintains a level of passenger comfort and safety on commercial aircraft. This is why your drink doesn't spill in your lap everytime the aircraft turns. My experience is primarily aircraft, but I would assume the uses are similar on marine vessels.
