looked at the fuel flows and noticed that number 3 was much lower
than the others that engine started popping and banging and the
torque started to fall off rapidly. We punched it out and
continued climbing. Seeing as how the weather was fine all over
we continued to Summerside.

You had some sort of torque meter to watch?

I wasn't aware such an instrument was used on aircraft, or
actually anything off of a dyno.

Oh yes Stephen, it's just about the main engine instrument, very
handy indeed...most large recips and even some turboprop a/c use
them...the C-130, P-3 Orion, Convair 580 to name a few, on these
three the torque gauges are called "Horse Power' but they
actually measure the amount of torque applied to the prop-shaft
by the engine.
