The mods keep materialising... Sunday afternoon was spent designing a new firewall
solution for 181.
After the crap ordeal changing out fuel hoses recently and the lack of easy access
a better option was created today.
Each piece is held in place by just two fixings each and tongue and groove interlocking.
The lower section is removable by undoing two setscrews mounted on the
inside upright face of the footwell and then sliding it downward. The upper
section is fixed by two set screws on the same inside footwell wall and remains
in situ and does not require removal until the frame is removed. There is provided
a large inspection hatch that is fixed by tongue and groove and two set
screws on the top lip of the upper section; removal is from the top once the
airbox is out of the way.
Looking forward to fitting this mod when ever the engine is next being removed
for any reason.

Alan
Thank you very much for this update. Very helpful indeed.
I have been offered a Garmin Aera 500 which would be a much neater and smaller
GPS input source than my Skymap IIIC. Would you happen to know if the Aera would
have the necessary output for the Trutrak?
Hope your strip has not become too waterlogged in all this rain. Would love to
fly up and see your AP in action. Sandown is currently closed as the grass is
so boggy but us residents can operate off the astro. Quite challenging to remain
within its 430m with just 80hp up front!
Best regards
David

David - it=99s my understanding that the Aera 500 would drive the
TruTrak OK. Way back in 2009-11-05 I logged in my build journal:
=9CNote that the just-announced Garmin aera 500 touchscreen GPS
appears to offer more screen area in a smaller box than the 296, and to
have superseded it (the 296 has disappeared from the Garmin website),
and Transair already have it listed at a lower price than the 296 - ho
hum.=9D
So it looks as though I had at that time checked the capability of the
Aera 500 to drive my TruTrak wing leveller and found it to be
compatible. I was just disappointed that it was =9Cnicer=9D,
smaller and cheaper than the GPSmap 296 to which I had already
committed!

David - I think I may have mentioned in a previous posting on this topic that I
am not yet actually flying in my Europa!
However, I have done some simple testing on the ground and it appears to be functioning
as desired.
My website <http://www.rowlandcarson.org.uk> is down now for some reason (I have raised a support ticket!) but when it comes back you should be able to find the relevant part of the journal on the entry for 22 Feb 2021.

| Subject: | Cockpit ventilation |
Good evening all,
I was thinking about cockpit ventilation the other day and thought that
I can let plenty of fresh air into the cabin from the two side vents,
but for proper ventilation, all that air needs to leave the cabin as well.
Then, I thought about putting some kind of ventilation grille in the
rear access panel. This should allow some air to flow through the
grille, then on through the fuselage and exit at the rear.
Not sure if this would give adequate venting, or work at all, any
thoughts please?
Thanks
Arwel

Ah, yes Roland. You did mention this but good to see that you have it working in
'ground mode'. Look forward to seeing more on your website once it is back up
and running.

Arwel
I have a small sliding hatch in the D-panel in the baggage bay bulkhead that does
exactly what you're suggesting. When this hatch is open, there is significantly
more draught flowing through the cockpit from the side vents. However, even
with it closed there seems to be enough leakage points in the cockpit (gaps
in door seals, throttle and finger brake lever slots, access hatch in tunnel
between seats to fuel selector valve etc) for there still to be plenty of ways
for air to flow out, at least for the flow you'd want at this time of year.
I find the bigger issue is that the side vents do not direct the incoming air where
you really want it, and mainly freeze your knees! There has been mention
by others of some very nicely designed rotating/flap type vents which do direct
air well, but probably need to be installed instead of the standard side vents
at time of building (or at least it looks like it would be quite a rework job
to fit them as replacements for the current side vents).
This winter I am going to experiment with installing some kind of simple moulded
ducting on the inside of the fuselage (maybe even just velcroed onto the carpet
lining for ultimate modifiability) placed over the existing vents. This would
try to 'scoop up' the air from the vents and angle it upwards/inwards. Not
sure if anyone else has tried this but would be interested to hear if they have.

Interesting posts Mr Area-51 confirmation is nice. I wonder if changing the needle
positions affect cruise mixture much or only mid range? And thats a sweet
firewall...

Thanks; still need to run it through relevant FAR's before production.
Re' adjusting Bing needle position; not going to even bother... If it aint broken,
why fix it? But if you want to experiment and know how to proficiently monitor
the affects, give it a go!
