Hi all,
For some reason that is hard to explain, I took my airplane out flying today
when it was really, really cold. I guess I hadn't had a "Europa fix" for 3
weeks.
Anyhow, the OAT was -13 centigrade and I noticed that my fuel burn for the
same power settings was significantly lower. At 28" @ 5000 I usually run at
5 US gallons an hour.
Today it was 4.2 I was wondering what was the major contributing factor.
For example, given that it was so cold, would the fuel density been
significantly different and I was still burning at the same pounds / per
hour rate, or was the dense air allowing the propeller / airfoil to be that
much more efficient ?
Second question for those that are more familiar with Bing carburetors.
When I reduce power from around 28" to 23 " the EGT's spike. If I do it too
quickly then the will hit the maximum allowable temperatures. Why is this,
and is there an adjustment that I can make ?
