Patrick,
My Europa wiring diagram (issue 4) for the Rotax 912 shows 6 wires connected
to the regulator. The two alternator wires go on Gand G. R, +B, and C
are effectively joined together and form the regulated supply lead to the
busbar. The alternator warning light is across C and L. Which wire are you
missing?
Brian Davies

No, but I would be interested to hear if you are having problems with the
regulator. I have an indicated nil charge and (referring to the wiring
diagram) have only 5 connections to attach to the 6 spade connectors on the
regulator. Much investigation has failed to find the missing wire.
Has anyone come across this strange anomaly?

Paul,
I cannot quote exact fuigures for the Europa but as an example (which is
not perfect as jet powered aircraft work to different parameters), I used to
fly in Sea Vixens and the best speed for maximum endurance i.e. for the maximum
time in the air regardless of the distance travelled, would be about 180
knots.
On the contrary, if you were going for the best range i.e. maximum distance
flown for a given fuel load, then you would beetle along at about 330 knots.
There is, as you will note, a big difference. The best range speed would
not vary with differing winds. The difference is not so large with a piston
engine, and you will not be concerned with max endurance - a case which would
only arise, usually, in the military field where you may have to stay on CAP
station for max time , for instance, waiting to intercept an incoming raid.
One of the peculiarities of GA is that, unlike military flying, there are
few, if any, tables to give best range and endurance speeds for differing
heights, air temperatures etc. I know of no source for these but maybe the
internet holds the answers somewhere!
It would be interesting to work out some figures for oneself but this would
entail a great deal of air time and expense - a job which used to be done for
us by test pilots who would then issue a complete set of pilot's notes with
all the info.
Good job for you if you have the time and inclination!!
Best wishes.
Patrick

Brian - yes I know which wires (from the alt) go to G and G (presumably
generator, ) and the two, I think judging by the wire gauge, to R and +B. I seem
to be missing the one which connects to L and I also have only one 20 gauge
wire connecting to C and not two (20 and 14) as per the wiring diagram.
Any ideas? Thanks for your interest.

Bryan, The plane which burnt out was a Cessna, involved in a take off
incident where he started of about 20 deg L of runway direction, came over
the hump to find himself heading for all the parked aircraft, hauled up to
get over the top of them and stalled in. The other was a landing incident
with I am told poorly controlled speed and approach path, putting it on the
ground when he should have gone around and bending his tricycle front wheel.
These are apparently the only accidents since the dawn of history when a DH
Rapide got lost and tried to put down there. Regards, David Joyce

Evening Bryan
Well I am based on hearsay from others who have been there, but if you
remember the accident stats from last year (or was it the previous year?)
there were 2 aeroplanes badly damaged, one of which I think caught fire.
The latest information I have is from a mate who visited a few weeks ago, he
described it as very rough with rocks sticking through the surface. It only
needs a combination of a slight bounce combined with a protruding rock
either under the tail wheel or under the prop and there you have the making
of a problem. Now the thought of dealing with a replacement prop on Lundy
just does not appeal to me - especially as my prop is NSI and any
replacement blades, if indeed they can still be got, are likely to take
months to arrive. Meanwhile, I would be faced with an aeroplane tied down,
in the open, on a rock in the Bristol Channel. It is simply not a risk I am
prepared to take.
Now if I still had my Cub I would not hesitate, plenty of prop clearance
with the tail down.
Regards
Pete

Hi Gary
Nothing I have heard about Lundy would encourage me to land a mono wheel
Europa there. The risks of a prop strike are just too high. Now a proper
tail dragger would be a different matter.
Regards
Pete

Patrick,
Looking at the Rotax installation manual Fig 29, page 17-1 (for the 912S) it
shows a slightly different way of wiring up the regulator and appears to
show only one wire on terminal C. This should, however, be 14 gauge. The
warning light is connected remote from the regulator terminal but ends up
the same as the Europa diagram. In other words the warning light is still
connected across terminals L and C, just achieved in another part of the
circuit. Having the warning light circuit missing should not stop the
regulator from working (I think!). There is, however a specific warning
note in the Rotax manual which says "Do not interupt the circuit between
Terminal C and +B of the rectifier- regulator during engine running as other
wise the charging will stop.
If you have no connection between B+ and C you will get no charging- I think
this is what you are describing. If so, simply putting a jumper lead
between the two terminals might fix your problem. Once it is charging, you
can find out if the warning light circuit is working.
Hope this helps
Brian

Our set up is Microair 760 and XCOM intercom. should I wire stick top
PTT switches with single screened cable or a twisted pair. The wiring
diagram for the radio has the latter but their wiring harness (which
we are not using ) has the former. Also should I connect the PTT
switch wires in at the mic jack end or back at the XCOM box.
So many things in this plane that I know so little about !!

Friends
David Watts article shows an attractive method of moving his fuselage about
and into his trailer by strapping his dolly on with bungee cords and moving
the fuselage (no doubt with a wing still attached) with wheel extended onto
a pair of ramps leading into his trailer. When the dolly wheels land on the
ramp he can retract the wheel and just use the dolly by backing off the ramp
or load the fuselage into the trailer.
Can anyone tell me David's email address or where does he hook the bungee
cords on to the fuselage please?
Sincerely

The PTT line normally shouldn't require shielding or twisted pair, and the manual
on MicroAir's web site doesn't show that.
You would want a handheld mic to work if plugged into the mic jack, so both the
control stick PTT and mic jack PTT lug get wired to the back of the XCOM box,
however convenient to do so.
