Hi Jim,
Understand your speed point, though running at 80% instead of 75% gives
you only a 2% speed gain. That's hardly an extra 2 knots.
Now, if speed is the main goal and longevity not a problem, why reduce
boost in descent ? As for the carbon issue, no Rotax 9xx I know of have
suffered of significant deposits.
Now saving fuel is indeed an honourable goal ;-)
