Hi Markoz, That explains alot, I obviously was not aware about a problem with Win8 and the minimum requirements mentioned. I have the same problem with the sound issue. I created a short cut on my keyboard for Aircraft Reload and it works just fine, I use a short cut for ALT/GEN key instead of the Battery Switch on FE panel, also Avionics Master key on my keyboard regarding the known Battery/Avionics issue. Other than that it is an awesome aircraft. I was thinking of purchasing another aircraft from CS but now, I am not to certain.

There has been a problem with the 727 sounds from the beginning.
I prefer the "rename the Captain_Sim.x707.sound.gau" fix but both fixes work equally well.
I also have mapped a key to the master avionics on/off command.

I also have Windows 8 and in my experience, there are no new problems introduced to any CS products.
After all, CS products are designed to work in FSX, not Windows xx, so as long as FSX is working properly, so will addon aircraft.
CS product support disclaimer was written before Vista SP2, Windows 7 and Windows 8  had been invented, so it is hardly surprising that they are not mentioned.
As to the oil pressure light fault, I don't see it and I wonder if the problem might lie in your default flight.
It is a much under estimated feature of FSX and unless the default flight is suited to the aircraft in question, numerous problems, particularly with more complex models, can appear.
