Hi Pete,
thanks.
A few comments to your answer:
Both simulators (PMDG and PSX) are not in direct competition - not saying one is better. Just a remark I can confirm and have seen from others, that both sims are really different e.g. PSX is modelling the circuit breakers, PMDG don't. This points to an underlying philosophical difference in the approach to systems - PSX is simulating the systems. PMDG is simulating the output of the systems. What is the difference? Probably very little if you are just jumping in and flying - but if you want to play with the engineering aspects and deeply understand the systems of the 744 the difference is huge.
And this from my point of view is needed in this market by many professionals especially cockpit builders, airlines and real pilots.
My point was only whether you are supportive with a new PSXUIPC :-)
Kind regards,
Carsten
