Tracy / Ernest: I don't know nothing about flying these
fancy computer controlled injected things and I could have probably never
figured out who used what for how long over how much distance; but, I put many a
mile on an old turbo normalized mooney and while my flight method depended on
distance of course, if close enough around, it usually consisted of climb to 14
or 15,000 and a couple of hundred feet per minute descent where clearance height
and pattern altitude would work out. The whole point of this is that flight
time and overall fuel consumption was usually reduced, sometimes even by as
much as a third. At the time I thought I had really found the ultimate "slipping
off the step" method of flight that I had often read about.

Actually it was 55 mpg during the descent
portion of flight. I was looking at MPG averages so speed never entered
the picture in my quick & dirty look at this.
But you suggest another way of cross checking the results. Let's
see, I think I agree with your miles traveled calcs so lets look at
it this way. I burned .106 gal in the 40 seconds of climb
and .125 gal during the 5 minutes of descent for a total of .231 gal.
9.4 miles divided by .231 gal gives 40.69 MPG. Not as good as I
got by averaging the MPG during each unit of time (48 mpg result)
but still a pretty good bump up from 30 mpg in level flight. Not
sure where the error is coming from.
Naturally my test results will have to be repeated many more times
before I accept them as
fact.
