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