Abstract
A method includes measuring a first rotational speed of a first element of a sprag clutch of a rotorcraft, measuring a second rotational speed of a second element of the sprag clutch, determining if the sprag clutch is in an overrunning condition, wherein the determining is based on the first rotational speed and the second rotational speed, generating an estimation of an instantaneous wear rate of the sprag clutch, wherein the estimation of the instantaneous wear rate is generated based on the first rotational speed and the second rotational speed, and displaying an indication of the estimation of the instantaneous wear rate of the sprag clutch. The method includes generating an estimation of an accumulated wear of the sprag clutch, wherein the estimation of the accumulated wear is based on the estimation of the instantaneous wear rate, and displaying an indication of the estimation of the accumulated wear.
