Recommended <strong>PT6A</strong> Engine Power Management<br />
Rating Philosophy<br />
P&WC’s power rating philosophy is to ensure the maximum likelihood<br />
that <strong>your</strong> <strong>PT6A</strong> engine will deliver the power specified in the POH / AFM<br />
throughout its overhaul life. To achieve this, all <strong>PT6A</strong> engine installations<br />
use torque as the primary power setting parameter. All other engine<br />
parameters are only monitored to verify they are within acceptable limits.<br />
The POH / AFM contains power setting information which must be used<br />
to determine the torque setting for all ratings which vary according to<br />
altitude, ambient temperature and aircraft weight. This is important<br />
because the P&WC rating philosophy is based on the engine being operated<br />
per the POH / AFM and maintained in accordance with the EMM / AMM<br />
including all applicable periodic inspection recommendations by P&WC.<br />
Operating the engine in accordance with the POH / AFM will achieve<br />
optimum reliability and durability while minimizing operating costs.<br />
