They (and everybody else) defines DOC as fuel, maitenance and overhaul
reserves. I know what the fuel consumption is on both aircraft (I was
considering buying a Merlin and have the flight manual. The Merlin is also
larger and heavier), I know what the maitenance is on both airplanes.
Having owned/flown a Marquise for 1200hrs bviously I know what it is on
MU-2s and I researched it on Merlins. The Merlin is much more complex to
maintain than a MU-2 which is why it requires about twice the maitenance
hours per flight hour. Then engines and props for both planes are the same,
so the reserves are identical.

So, in conclusion; the Merlin uses more fuel AND requires more maitenance
AND the reserves are identical. The Merlin's DOC HAS to be higher.

There are numerous other examples of errors in the chart. The Cheyenne
400LS is shown as less than either the Merlin or the Marquise. It burns
MUCH more fuel AND MUCH higher maitenance costs AND MUCH higher reserves.

The chart is worthless.

Do you believe all infomation that you read on the net?

There are some problems with this data. The first thing that I
noticed
is
that a Merlin has lower operating cost than a Marquise. I happen to
know
that a Merlin uses more fuel, has twice the maitenance cost per
flight
hour
and is slower. It can't possible have a lower DOC, so the data is
inaccurate..

Maybe they're taking more into account than YOU are.
