Compression & Power
I have just been told that the left engine of my Aztec has zero compression on two pots.
Immediately prior to the CofA on which this was found, I did the test flight, and with the right engine feathered the SE climb was on the reasonable side of adequate.
So, to my questions: what proportion of the power of a 6-pot engine would you expect to be lost if there is no compression on two of them?
Does zero compression = zero power, or is that too simplistic?
TIA
