i mean how would u separate the reading of both rate of roll and rate of turn at the same time from the same instrument.
The most convenient place I could find online with a diagram was wikipedia. Just search and click. Or go to FAA.gov and download from the airplane flying handbook.
It's the orientation of the gyro rotor assembly within the instrument case.The turn coordinator is a hybrid of a yaw rate gyro and a roll rate gyro. One advantage of this arrangement is that the instrument displaces in the correct direction during roll in to a turn. Center the inclinometer ball to achieve calibrated accuracy.
