The Turn Coordinator

Wed Jan 16, 2013 2:26 am

"The turn coordinator is an advanced development of the earlier turn indicator. It is similar to the turn indicator instrument, except that its single gimbal is raised at the front by 30 degrees so that the instrument is sensitive to both roll and yaw, and it begins to indicate a turn as soon as the roll-in begins"

I would like to know how by raising the gimbal at the front by 30 degrees the instrument become sensitive to roll?

In the turn indicator the gimbal is horizontal, so the gyro is only sensitive in one axis. In a turn coordinator, the gimbal is canted, and so you get sensitivity in two axes. The gyro in a turn indicator only has a single gimbal. The mounting itself hinders it from turning in more than one axis.

Also by having the gyro at the 30 degree angle makes the force applied 90 degrees ahead (procession) , so it is able to sense both turn and slip.
