...fascinating topic...


Raimo...a couple of questions...


- When you say you are not a contortionist, are you saying that...while 
sitting in the left seat cockpit...you either CANNOT, or find it 
extremely difficult to, pull the rear of your window/door inward if the 
rear shoot-bolt doesn't engage properly?...

If I had to pull the rear of my door inward, that would be quite 
challenging. Happily it is not necessary in Romeo Tango=B4s case at all, 
because it goes =93automatically=94 right. My practise is to press 
window frame down by my left elbow and same time push the lever gently 
fore. 


- If so, what happens when you don't get a "green" lite? 

I get it always. My doors are not very tight. I did not used Europa 
suplied door rubber weather strip. I found my own version of the rubber 
seal. But if I could not get =93green=94, I would try again in that 
case. What else?


- How often do you not get a "green" lite after latching your 
window/door? 

In my case so far never. Notice: in my case. You cannot trust it. Me 
neither.


What I'm trying to understand is whether or not your window/door 
installation was perfect or near perfect resulting in virtually 100% 
engagement of rear shoot-bolt when latching and thus your warning lite 
system merely gives you some peace of mind.

When building I did not know how easy it will be to close the doors when 
completed. I built the warning systems just in case. BUT ' one single 
time having a rear bolt outside is too much and can lead to fatal. That 
is why I would build it again with this knowledge. In fact ' when the 
doors close easily you are not concentrating to this procedure. Easy 
closing doors are kind of risk...that is why you also need a warning 
system ' positive or negative or both.


As mentioned previously, I feared that my rear shoot-bolts would NOT 
engage properly UNLESS I was able to include some means of pulling the 
rear of the window inward...and my little ergonomic investigation showed 
me that if I installed a little tab on the window frame...approximately 
in line with the CM "head rest"...this would do the trick, without my 
needing to be a contortionist. This works for both port and stbd windows 
as I, like others, do not want to depend on a passenger to tell me if 
everything's aok.

After I had read this I went to my winter-hangar, which is behind the 
wall of my office. Sat down to the P1 seat and noticed this place for a 
little tab in line with head rest would do without a snakebody. Ten 
inches back and it would be hard to reach it. But IF you once forget to 
use your tab OR it is not necessary to use it at all ' the destiny is 
behind you.


(For the port window, I reach my right arm across my chest to pull the 
tab inward while my left hand pushes the door handle forward...for the 
stdb window, I reach my right arm behind the passenger's "head rest" and 
pull inward while passenger [or I] push the door handle forward...no 
contorting necessary...and whether I have a warning lite system or not, 
I still anticipate going thru these motions when securing the 
window/doors.)

If you happen to manage to build perfect doors, they will be closed very 
easily. As advertised. Then there is a risk sometimes for some reason 
you are a bit more careless than normal and your rear bolt is out and 
you have no idea about that w/o a warning device until you notice that 
airborne at 5000 ft and start to fight for your passenger(s), plane and 
your soul.

Build a warning or/and ok systems. I will send you all the necessary 
bits (a DC12V led with a nice collar (colour of your choise), two 
microswithes and 10ft of high quality teflon aviation wire and a 
schematic drawing. How about that (valid only for you and one week 
only)? 

What more you need?

Build warning devices ' fly more safe!
