John deakin manifold pressure sensor

Now that previous columns have littered the runway with theory and attempted to explain manifold pressure, propeller RPM, and mixture, I'd like to present some suggestions for in-flight techniques to extract better performance from these engines.

Some of it will be a little repetitive from prior columns in an attempt to make this column more or less "sink-alone."

Much to my amazement, these columns have been very well received.

The manifold pressure sensor is measuring the pressure inside the manifold (see, get it?!), against a 0 reference.

John Deakin has an interesting article on how air gets into the engine and why “Manifold Pressure” is really “Suction Pressure”.

I'd like to thank you for reading them, and my special thanks to those who have taken the time and trouble to comment in the public message threads, or via email.

Speaking of which, please note that it is to everyone's advantage if you leave any questions or comments as public replies, rather than emailing me privately.

There are several compelling reasons for this. Most important, everyone learns from a public exchange, and often others will have wanted to post the same comment or question, but didn't wan
