Turn Coordinator - Speed error
Hi !
Frow what I have understood, a turn coordinator works thanks to the torque applied on its side (yawing).
This force is redirected at 90 degrees which makes it bank on the side (precession).
This bank is then calibrated by a spring to indicate if we are yawing at rate 1 turn (or not).
By reading the Oxford manual I came threw something I can't understand.
It says that if the gyro is underspeeding, it will underturn.
I would have thought that if the gyro underspeeds, its rigidity would decrease.
And as the rigidity decreases the precession would increase (and thus increase the indicated turn rate).
Thanks for your explanation.
