Manifold and ambient pressure

Post by edwardsp1916 »

Great aircraft, already logged about 150 hours so firstly, thank you to the A2a team for their continuing efforts to produce the best aircraft they can and continuing to set new standards in the FS world.

My question relates to the manifold pressure gauge an it's reading with the engine off. Currently at an airfield and current QNH is 29.99 however the MP instrument shows approx 29.00. Is this correct?

Regards

What would be the airfield elevation in question? If you rotated your altimeter to read zero, then the Kollsman window should match the manifold pressure indication.

Guessing you are at 950ft approximately for standard conditions...

Spot on all! My error, apologies. I was setting the QNH not QFE.

Thank you.
