okay welcome to the channel. We are in the Mooney today just doing a maintenance test flight on the
turbocharged system we have been cleared to sixteen thousand five hundred feet currently
and we're just climbing out. (ATC) "just for my planning purposes tell me again what your plan
is i've got you flight planned over the Wiarton VOR and back are you planning on any approaches
or anything like that?" No approaches just heading out towards Wiarton and as I said just to do some
maintenance checks on the turbocharged system once we've completed those we'll be turning
around and heading back to Peterborough airport. "NPE understood thank you" So yes we're cleared up
the 16500ft I'm just starting to bring the turbo on now as we're down to 23 manifold pressure we're
just coming up on 7 000 feet we're climbing at about 125 indicated right now doing 700
feet a minute 34 gallons of fuel on board when we left about 60 pounds of baggage and just myself
Just slowly opening up that wastegate so I don't get a sudden surge.
It's got to flip a trapdoor against the inflowing air in the airbox so it does tend to kind of
all of a sudden grab! Must be getting pretty close there there we go when we feel the boost nice!
So we're 16 500 feet we're level we're indicating about 135 knots on the airspeed indicator that's
giving us a true air speed of 177 knots I'm fighting a 59 knot headwind right now
now we've got a bit of leakage in our turbocharger setup in the air box I'm assuming which is a
common problem with these because I'm now only able to maintain 26 inches of manifold pressure
and max would be 27 up to 25 000 feet so we've already started to lose manifold pressure so we're
wide open on the wastegate and we're now limited to 26 inches so
a little bit of work and attention maybe around that air box see if we can tidy up a few things.
For the last 2 000 feet of the climb I had to reduce the climb rate to about 300 feet a minute
and increase the indicated airspeed as we were approaching 450 degrees
on the CHT that is a complaint with the aircraft
about it getting hot even with full rich on the mixture to try and keep temperatures down
We sure are moving but it's a lot of fuel to be burning for not a massive increase in speed.
Right now I'm just in the yellow arc so I've got the cowl flaps closed as
I've got an airspeed limitation on them and I'm sitting at about 410 Fahrenheit crews on the CHT
and that's with an outside air temperature of well below freezing
we are only grounding
120 knots with our 60 knot headwind that's quite something that really is quite something
So pretty happy with that really both parts but I think a bit of improvement could be made
there this model is missing initial cowling mod that most of the early ones got I think
that's going to become absolutely mandatory to keep our CHT and oil temperatures down
(ATC) "November Papa Echo clear direct to Peterborough airport is approved and
descent down to 12.5 or below is also approved" Roger that for November Papa Echo we're just going
to start a descent right for 2000 feet and we should be there by the time we get to Peterborough
wow that is just gorgeous
I don't think we can make at a full stop I think we got to do a touch and go
look at that sunset
okay final landing check mixture rich, prop high rpm for the go around,
gear down and latched one green, we're landing on land, flaps are set at full
short final two seven touch and go Peterborough yeah we gotta go down and try that again
that's just far too nice to stop after one
plus it's freaking cold outside
a little too much speed so I floated a bit but very happy with actual landing itself
