Hi! Fred/Raimo.
I have a couple of wood =93pull handles=94 on the rear portion of each
door to
ensure they are shut. I have to say they are never used because I would
need
to be a damn contortionist to get at them from the Europa seat
positions. If
Raimo=92s system is fool proof then go for it but I use my eyes on the
starboard side and ask the passenger to check port side to verify they
are
closed and the bolt is =93home=94.
Over 800 hours perhaps 900 and never yet a take off with a door not
properly
closed.
Regards
Bob Harrison (G-PTAG)

that is true. An ideal Europa=B4s weight is around 350 kgs (below 790
lbs).
That is possible w/o any extra. Also, it takes time to plan and build
extra.
They are also not free!
I have that extra 70 kgs (160 lbs). More is coming!
Why?
- for a good look and luxury (painting, leather, DVD, refridgerator,
heating
and defrost system etc, golden register plate etc means about 15 kgs 34
lbs
penalty).
- for a safety (warning systems, extra navigation, autopilot, 2nd GPS,
TCAS,
alarms, horn, nav-lights, 3 strobos, landing and taxi lights, panel and
a
cockpit illumination etc, real aviation safety belts x 4 etc means about
20
kgs 44 lbs penalty).
- for a speed and efficiency (CS-prop, very finished surfaces and glossy
painting means about 20 kgs 44 lbs penalty).
- for a family (it is 2+2 seater and that was for structural reasons and
extra belts and four place intercom about 10 kgs 22 lbs penalty).
- for me and my wife (good tempur seats, some small details, decoration
etc
say 5 kgs 11 lbs penalty)

That is all together 70 kgs and those kilos make Romeo Tango
personalized
for our taste.
For me it was the best part of the building to think about all these
extras
and judge what to do and what do not.
***
Door bolts warning system:
2xmicroswitch (4 is not necessary)
some wire
one led (two is not necessary)
connected to the fuse you already have
Penalty is not more than 0,1 kg = 0,225 lbs.
You will build it about 2 hours only.
And spend money let=B4s say few bugs like 20 dollars.
It is a bit ackward to check rearbolts. Really. At least my body does
not
want to twist to the left so much. It is dangerous to your healthy. It
is
human not to do it always. But it is easy to check one green led. Very
easy!
You can still have your statement PULL DOOR INWARD BEFORE LATCHING and
then
verify you have the green led.
Do it, for me please!

All,
I have followed this thread with interest as it seems to embody the
tension
between keeping things simple on one hand and fitting out our planes
sufficiently to ensure safe flight on the other.
I've paid some attention to the issue of ensuring the rear shoot-bolts
engage because when fitting the doors, I found that the rear portion of
the
door seemed to spring outward just enough for the rear shoot-bolts to
miss
the aluminum tubing which prevented proper closure...not good!
After sitting in the left seat...twisting my body and reaching about to
determine where I could reach in order to pull in the aft portion of the
door prior to closing the lever and engaging the shoot-bolts...I
installed a
simple tab on the window frames (both port and stbd) which I could grip
and
pull inward. One thing I noticed while checking out my little ergonomics
exercise was that I found that I could not feel whether or not the
shoot-bolts were properly engaged or not, nor could I readily see
likewise.
The fundemental idea I took away from these exercises was that it was
essential to pull the rear portion of the window/door inward BEFORE
moving
the latching handle forward.
As luck would have it, after installing the plexiglas windows, I found
that
the additional weight completely eliminates the tendency for the rear
portion of the window/door to spring outward and for the shoot-bolts to
not
engage; however, I have not as yet fitted the tubular rubber seal...so
perhaps the conditions may change.
My hunch at this point is that my checklist MUST include an item
stating:
PULL DOOR INWARD BEFORE LATCHING.
For the moment, I'm content with that and will not add the additional
complexity of a warning light system. I've had a look at about 20
Europas
and, I believe, have yet to see a microswitch/LED installation...I'm
wondering how common are such installations.
