Jim and all,
Those numbers correspond to rather high settings. While the engine may
run at 100 % continuous, what is the point for a cruise above 75 % ?
Here are excerpts from the 914 operator's manual :
/100 % power is 5500 RPM / 35"
75 % power is 5000 RPM / 31"
65 % power is 4800 RPM / 29"/
/10.3.8) Engine shut-off
Normally the cooling down of the engine during descending and taxiing
will be sufficient to allow the engine to be shut off as soon as the
aircraft is stopped.
At increased operating temperatures continue to idle until temperature
will drop to "normal operation level", see Chapter 10.1).
Allow a cooling run of at least 1 min. as an engine shu-off at high
temperature is especially harmful for the turbo charger. Carburizing oil
might block the oil supply and firing in the muffler can occur.
