I measured mine at very close to 10 litres and that should hold good in
the air in roughly level flight as the return line empties into the
reserve side keeping it constantly topped up in spite of turbulence. At
least it should do, if you have got your plumbing right - ref the
directive and other info relating to the GBYSA disaster last year.

Dumb question for the avionics experts: why not simply install the active gps antenna
wart on top of the removable instrument panel on the glare shield and shorten
the cable and terminate with a new matched connector using the correct
crimper? Is there a magnetomer integrated into that "antenna"?
Thx,

I installed the Garmin 430W in my Europa and it came with the eight foot cable.
I was told not to coil it. I place the antenna just above the Hat Rack on the
D bulkhead, inside, then place the cable around the edge under the co-pilot's
door ledge and then under the baggage floor then up to the antenna. The 430
has worked beautifully.

Hi Remi,
Panel mounted EFIS units with internal GPS antennas are prone to interferen
ce depending on installation.
I=92ve always used an external antenna in my practice. I mount them to a m
etal inverted hat shape to the top inside of the panel. Early WAAS GPS ant
ennas (those less expensive much lighter plastic type) work better when att
ached to a metal surface. The large, heavy Garmin types have a metal base s
o a simple fiberglass mount in the panel works OK. The Europa, being fibe
rglass, does not impede radio signals but the surrounding metal globs aroun
d these items do. The proximity of other receiver antennas for some reason
do not seem to bother one another. Go figure.
As far as antennas, I have always made my own BNC cables and connectors and
never have had a problem once ohmed out. RG 58/400 cable is fairly bulky
and are easy to make to proper length. Manufacturers normally resist allow
ing amateurs to modify their cables for obvious reasons, but if you have th
e tools and know how, shortening a cable is perfectly fine. I just prefer
to remake the cable completely. The small S type connectors and antenna wi
re, I coil up (because it is a small flexible wire) and I place the coil in
the panel away from the GPS antenna and all is fine as long as the coiled
antenna wire is not wound around the antenna. (I put mine along side the E
FIS unit as its metal case should prevent interference.) If you coil you
r antenna wire, just use care where you put the coil. Between the Garmin
/Blue Mountain/EFIS of choice and the altimeter has always worked for me.
Be flexible, because if it doesn=92t work in one spot it may in another. T
oo bad the panel has to go in and out if you are wrong.
Electronics do go out of calibration from time to time, so a recalibration
of altimeter, airspeed and EFIS systems are necessary over the life of an E
FIS/NAV unit. It just costs money and time, but not extra weight.

Bud Yerly

Subject: Europa-List: GPS antenna cable length
This is a question for avionics gurus. After one full year of good service,
my G5 EFIS with its enabled internal GPS antenna started to display wrong
attitude information. After talking to the G3X team at Garmin, a software u
pdate fixed the issue, but after reviewing the recorded data of one of my f
lights, they came back to me and suggested I install an external antenna to
improve the GPS reception. So I purchased a GA26C antenna (picture attache
d). The antenna comes ready for use with an 8 ft cable and BNC connector. I
need only 2 ft to install the antenna on top of the instrument panel, ther
efore my questions: performance wise, is there an inconvenience to install
the antenna as it is and attach the loops of extra cable length together? I
s it worth cutting the extra length and install a new BNC connector? Would
that reduce possible losses and/or susceptibility to electromagnetic interf
erences ?

For UK pilots who have not already responded - The consultation over the
Brize Norton airspace proposals closes on 5th April. This is a totally
unreasonable airspace grab threatening a large part of GA airspace in
central southern England, and in doing so likely to adversely effect air
safety by producing tight or tighter choke points around it. Please send
in an objection. The BGA site has an excellent guide to the topic with
well argued criticism and links to where to lodge your objection. See

| Subject: | Black Brake Pipe........ |
Bob,
I see this all the time in the US. Getting the black pipe is not easy as i
t is UK type pipe fittings are non aviation.
The 6mm tubing used is for Kart operations in the UK as are the fittings.
If Karen can=92t supply try cometkartsales.com for this specific tubing and
fittings may help.
Note For North American Customers: In my shop I convert the brake lines t
o all Matco for my clients when I can. Lines and fittings all match all th
e time. For those of you in the UK, I know the approval of same or better
using an aircraft brake manufacturer is quick and easy. I also note that,
on a re-plumb of a trigear, will use the 1/16 inch Matco lines and fittings
. Very good stuff and from a consistent manufacturer. Just slip the small
er line into the old tubing for a quick, permanent and properly operating r
epair. Some notes are in the .pdf attached.

Bud Yerly

| Subject: | saddle tank? Fuel Tank Flush and Filters. |
Alan,
9.5 liters or 2.5 US gallons on the reserve side. (Basically the same thin
g on the other side if you want to know.)
Calibration of the fuel sight gauge, fuel flow and fuel gauge are important
. I measure each tank volume, check and calibrate my fuel flow using a sma
ll valve to restrict the flow and hold pressure at about 4 PSI to get the f
low right and of course flush my fuel system all at the same time. Old tan
ks held 18 US gallons with reserve. New tanks slightly more. My trigear f
uelled to the neck, holds just at 20 gallons. I normally plan 15 gallons f
or flight as my sight gauge is at the arm rest and the fuel left is one hou
r total left in the main and reserve.
No tank is clean on the inside, and a cleaning and thorough flush is necess
ary. You have a fuel pump, and electric pumps work out of the box and if t
hey are going to fail, fail in the first few hours. Why not run it prior t
o engine start cycling fuel through the system and calibrating the tank. I
even make lines on the tank with the wings detached to use should I need t
o change out the sight gauge line (required about every 5 years...
Filtration of the fuel system is a mixed bag of personal tastes. I make my
system exactly (well almost) like in the book. I differ on my site gauge
install and my vent system has a drain installed out the bottom of the airc
raft to prevent staining. Just check for insects and mud. Gascolators hav
e course filters on the whole, tend to leak as they have a gasket, must be
the lowest point in the fuel system which is hard to do in a Europa without
making a bump in the belly, if mounted high will suck air if the gasket dr
ies out, and leak or worse yet, prevent the fuel pump from pulling the rema
ining fuel out of the tank lower than the gascolator, robbing you of fuel.
But, they have been around forever on tractors, boats and airplanes becaus
e mechanics never change and work fine in a farm environment. Andair makes
the best in my opinion and can be placed on the suction as well as pressur
e side with its excellent O ring seals and is equipped with a 100 and 70 mi
cron filter and is not very tall. But follow Andy=92s instruction at Andai
r and put it as the lowest point in the system if possible.
Filters: 40-50 micron is best. I have written on this before and still us
e the Mr. Gasket/Purolator type. The Mr. Gasket/Purolator glass filters re
quire a technique. You can over and under torque them and they will leak b
y unscrewing themselves, a spring helps prevents loosening of the internal
nut that holds the filter in place and the filter element can be put in wro
ng. I=92ve used them for 15 years and never had a problem because I tighte
n them properly and use a light spring. Just pay attention, use quality fi
ttings and hose, and I put them in my seat pan for easy inspection plus put
in a drain should it leak. I am getting lazy as every 25 hour inspection
(really thorough preflight) over the last 10 years I have found no contamin
ation in my filters to speak of so I never check my fuel filters on preflig
ht any longer.
Make the filters easy to remove without leaking fittings or draining of the
fuel system. Again, I have written on my fittings for this before. I use
CPC valved fittings without fail. Keep a set of O rings for the QDs as th
ey do eventually wear out or though improper use, get cut.
The Europa plastic fuel tank does not sweat so, in my experience, water in
the fuel is normally not a problem even in colder damp conditions. But che
ck anyway.
Fuel quality is imperative. If you have water in your fuel tank, it has be
en my experience that the owner put it there using car gas with ethanol. A
viation suppliers of AV Gas tend to have excellent filtration and water tra
ps. Quality MOGAS stations do also. The metal jerry cans in my shop are a
ll gone as they sweat and water collects if the cap is not perfectly sealed
. I still pre-filter my auto fuel (a filtered funnel by =91Mr. Funnel=92 w
orks fine) and never had water in a tank. Ethanol can be a real problem.
Over time the octane drops off, it absorbs water readily from the air, even
in the fuel vapor and vent system of the fully fueled aircraft tank, and
it tends to permeate non EPA (R-9 or better) fuel lines making a stinky sme
ll. AV Gas is great, except for the cost, higher maintenance, engine lead
deposit woes, and other lead problems. Non Ethanol premium auto fuel is pr
eferred in a Rotax. (94 Octane unleaded aviation fuel is starting to show
up around the States thank God.)
Bottom line, clean and calibrate your fuel system, make it easy to maintain
, and service, use components that have been tested and proven and you=92ll
be fine.

Bud Yerly

Roger,
Theres really not much to view. There is only a listing of the articles from issue
13 to 48(Final). The Tech Talk articles are not available on line.
If you are a member, just log in and you should be able to view the listing. To
read the actual articles you need access to the various issues of the Europa
Aircraft News or Europa Flyer themselves. Im not sure where you can get those
back issues. They do not seem to be available on the web site.
