Power Check for Engines with Constant Speed Props

[Randy Sohn]

For years I have monitored manifold pressure during run-up

We taught on run-ups (Reese AFB, B-25's) to advance the throttles to an RPM (1700 in that case) where the props were still resting on the stops (Non-governoring) and check the MP required for that, then proceed with the run-up.

For years I have monitored manifold pressure during run-up to be sure the engine was making power; if more than usual MP was required to get run-up rpm, something was wrong. Now I am trying to figure out where I learned this. At first, I thought it was from Deakin, but I cannot find such a thing in any of his columns. Anyone remember a thread here that discussed this?

Thanks!
