| Subject: | Re: Weight and Balance question |
John,
Weight and balance is an interesting subject and everyone has their opinion on
whats best.
While a datum of 29,25 forward of the joggle might seem strange initially, it could
have been 30 or any other number forward of the entire aircraft. This simplifies
the calculation by only having to deal with positive number and thus reducing
the likelihood of errors when calculating.
The 2 examples I found in the LAA document you gave a link to showed a Cloudpusher
aircraft with the datum 3191mm forward of the C of G which put it on the nose
of the aircraft and a Sportster with the datum 70 in front of the leading
edge, a small distance in front of the aircraft.
I dont think Ivan or Andy were far off the mark, or maybe 0,75 for a whole number.

As a matter of interest, has anyone recorded the station points for the various
bulkheads in the Europa such as 'front of seats', 'seats rear vertical face',
'forward face of baggage bay', 'aft face of baggage well', etc?

Whilst it is true any position can be chosen, there is a very valid and logi
cal reason why the reference point was chosen to be 29.25=9D forward o
f the joggle.
The reference point FS 0.00 for the original Classic was the forward face of
the engine cowl behind the spinner. This position corresponds to 29.25
=9D forward of the joggle on the Classic and the XS. The front face of the
cowl on the XS is further forward to accommodate the relocated engine posit
ion on the XS.

Thank you Bud. And apologies for not replying sooner since I initially missed your
reply.
I will digest all this info. I can tell you that I did the 1000'/135kts test since
it was easy to do by removing the pitot/static mast at the wing. It showed
no leaks. I assume this will discard any leaks at the instrument or panel level
since it is all connected.
I completed the IAS check and it is within a couple of knots. Very accurate.
I will proceed to trouble shoot the components as you indicate. The Winter is new
(but has been sitting for a long time). The altimeter is a quality TSO unit
that looks like new but I bought used so a little suspicion there. I will isolate
and test.
Regarding flying N11EU, I love it, but the landing in anything other than calm
or very light winds has been a bit of a challenge (hard rwy). I also find that
my airplane floats and floats and floats. I got my speed down to 55 over the
numbers before the flare and that helps a little. I am touching down at around
45-40 (checked by on-board video, ASI vs GPS). Anything higher than that and
it's main first (bad). If there is a little bit of gusty wind that makes for an
interesting flare and being that slow worries me a little.
But I am getting better. 7 hours so far. Sweet flying airplane.
Best Regards,
Chris

Thanks for the reply's guys. Ken do you have the part numbers for the bearings.
Or do you have a link to them. I would like to get them ordered before I start
the permit inspection.
