Couple more questions from XM569!
« on: March 08, 2014, 10:51:46 PM »
Today I had a couple of questions that I couldn't answer, never been asked these before and never thought about them myself so here goes.

Can someone identify what these bits of equipment are used for;

1 - This glass tube connected with the rubber tube is lying inside the porthole next to the Nav Radars position. I think there should be one on the AEO's side as well but it's missing in XM569.
Do you know what it is and what it is used for?


2 - This little clip is on the side of the AEO and Nav Radars seats. What it is used for I have no idea and can't begin to imagine! Any help would be much appreciated.


Thanks very much

 No idea but could it be like a silicon damp detector to see if there is a break in the seal?

I think it's a silica gel type container to keep the windows mist free.

Is the clip at the side of the back rest?  If so it could be to allow the crew movement down the back.

Thanks Pam, could be to demist the window, maybe the tube is connected to the gap between the panes of glass to stop the interior of it getting damp. Good answer, unless anyone knows different of course  ;D

Ref the clip, I can't see how it would work, it just goes up and down to the extent shown in the photo. Doesn't even seem capable of holding anything, unless whatever it holds is above it maybe.

According to our tame ex Vulcan pilot here in Bournemouth... picture 1 is indeed a silica filled device that removes moisture from between the window seals.

It starts off blue and when it turned pink... it needed changing.

As for the clip - it might be the swivel release for the seats ?

I think the clip was to hold the parachute pack into the seat back.

I'll never give up on the dream!

There is no such thing as an "ex-Vulcan pilot" - only a retired Vulcan pilot!!

Ok - Seriously - The tube contains Silica Gell and connects via the rubber and perspex tube to a sorbo ring fitted between the two panes of the window, the moisture is pulled into the sorbo ring and flows down to the Silica gell tube, that turns an nice shade of white, and upsets the AF fitters some what.

Agreed on the silica gel dessicant for the double glazing, have a similar system on my Canberra cockpit. I sat up front so have no experience of the rear seats but wondered if it acted a a handle to swivel the seats for ingress if it is only on the inboard edge of the seats.
Consulting : If you are not part of the solution, there's good money to be made prolonging the problem!

Ok, now I've looked at the rear crew seats.....

I know the clip is to hold the top of the pack into the seat.  The packs are very heavy as they contain an emergency oxygen bottle.

The two clips higher up on the seat are to hold the shoulder straps

Thanks once again Sam and everyone else that has responded.
The 'Ears' higher up the seat I was advised about some time ago, I think that was you again Sam, and when you look at them there is no other earthly reason for them to exist otherwise but what an essential job they do.

That little sticking out clip had me baffled so thanks very much for the confirmation about the holding the parachute into the seat. I guess it moves very easily when they had to get out of the seats in an emergency with the inflatable cushion below pushing them upwards.

The silica gel containers are white so looks like they are still serviceable and working, unless it's white mould!!

Thanks again, very much appreciated as always.
