"Peter Duniho" wrote in message In addition to the "burp", you should
also note increased fuel flow or
higher EGT/TIT temperatures (depending on whether you readjust the mixture
to compensate for the less-complete combustion). Nothing wrong with
checking the mags after landing, of course, but I've never heard of a mag
failing in flight where there was NO actual indication that it had failed.

There were no other indications. Many magneto installations can be tuned so
that there is no perceptible rpm drop during a mag check. At 8500 feet with
normally aspirated engines and with the original EGT probes and gauges in a
heavily used charter airplane, it is possible that there won't be
perceptible differences after a mag failure.

Just wondering, what do you think will be the oil temperature indications of
an engine losing oil? What about cylinder head temps? I know the book
answers and I know the real world answers.
