In light aircraft normally we found either Turn co -ordinator or Turn & Slip Indicator.But there are some basic difference between them............
Because of the way the Gyro is mounted the Turn & slip indicator only shows the rate of turn in degress per sec.
But in Turn Co-ordinator the Gyro is set at an angle or canted ,so it can initially also show Roll rate.Once the Roll stabilizes it indicates rate of turn.
Both instrument indicate turn direction & quality ( Co-ordination),and also serve as a back up source of bank information in the event an attitude indicator fails.
The Gyro in the turn & slip indicator rotates in the vertical plane ,corresponding to the airplanes longitudinal axis.A single gimble limits the planes in which the gyrop is tilt & a spring tries to returnit to center .
Because of precession , ayawing force causes the gyro to tilt left or right as viewed from the pilot's seat.
The turn & slip indicator uses a pointer called the turn needle to show the direction & rate of turn.
The Gimble in the turn co-ordinator is canted therefore its gyro can sense both rate of roll & rate of turn .since turn co-ordinator are more prevelent in training.
The Turn co-ordinator can be used to establish & maintain a standard rate turn by aligning the wing of the miniature airplane with the turn index. It indicates only the rate & direction of turns ,it does not display a specific angle of bank.
Standard Rate Turn: A turn of 3 degree per sec . A complete 360 degree turn takes 2 min.
A rule of thumb for determining the appropriate bank angle required for a standard rate turn is to divide the True Airspeed by 10 and add one-half the result.
For example at 120 knots approximately 18 degree of bank is required.
To calculate this
Divide the true airspeed by 10--------120/10=12.
add one half of result -------------12+6=18.
