What Is This By The Window Of This TU-154?

Thu Sep 21, 2006 1:35 pm

IN this interior shot of this Kras Air Tu-154 below you will notice on either side just in front of the emergency exits, what looks like a filing cabinet with imitation wood grain (??) where the window seat should be.
I thought at first that someone was transporting something and taking advantage of the two across seating roominess like the seat behind but they look like exactly the same things on both sides, and also appear, although it is hard to tell sort of attached to the plane.

Does anyone know what it is?

It's where they store the evacuation slides.

Looks like a Storage Cabinet used by the Crew for Emergency Equipment.

As I already said, it's for the slide. I've been sitting next to this box on several flights, reading the instructions on how to operate it.

This is probably a stupid question...

but if the slide is kept in a box inside the aircraft, how does it deploy outside the aircraft?

I don't remember all details, as it is a few years since I read the instructions, but it goes something like this:

Pull the handle in front of the box so that the front panel comes down 90 degrees and lies flat on the floor. The slide sits on top (inside) of that panel. After you have opened and removed the emergency exit, pulling another handle will inflate the slide, which automatically flies out the door.

Is there a safety mechanism that prevents accidental deployment should say the door still be closed? Considering F/A mishaps on US and European jets, I wonder what would happen if a passenger got bored...

This appears to be similar to the configuration of the evacuation slide on Fokker 28 aircraft at door 1R.

On the F28, the slide pack is contained inside a "cabinet" adjacent to the door. In an evacuation, the door is opened and the slide pack is manually pulled from the cabinet. Now it is lying across the door sill.

The slide pack is then pushed or kicked out of the aircraft. It is this action which inflates the slide once it falls out. It is for this reason (on F28 anyhow), the slide cannot be inflated inside the aircraft.

Sometimes the Tu-154 box is also a lot shorter, but wider, and takes up the place of a seat so makes a handy footrest. You aren't likely to survive a crash anyway, so who really cares if it is complicated? The Tu-134 has a knotted rope underneath the mid-cabin emergency exit seats that you are supposed to throw out over the wing....

Notice how the passengers on either side next to the slide box are taking advantage of the extra surface to put their drinks. So much for looking out the window.

Slides on Tupolevs are not fully automatic like on Airbus and Boeing planes. Not only do you need to manually remove it from the storage container, but you must also initiate the inflation by properly causing it to inflate. I spoke with a flight attendant on an Aeroflot Tu154 a few months ago and she explained the process to me, which seemed horribly complicated. I don't feel as safe in those planes for this reason especially. In an emergency, it would be quiet difficult for someone not familiar with the exit to operate it correctly while panicking in the aftermath of an incident. It is no where near as easy as pull the cover off and pull the handle or just rotate a lever like on Airbus or Boeing planes.
If you have never designed an airplane part before, let the real designers do the work!

Do you mean Raft.As the Slide needs to be door mounted & armed to deploy on Emergency Door Opening.
Im Surprised an Emergency would give that comfort level.

No, I mean slide. RoseFlyer explained in reply 11 that the slides on Tupolevs are not fully automatic.

Seems to me that safety was an afterthought on these a/c. Not very smart...and not very safe.

One has to keep in mind the Soviet mentality that went into their design. Crashes were an embarrasment and the less information about it, the better. There is also an undercurrent of fatalism on the part of Russians that sometimes leads to a lack of safety (Masha Gessen from the Moscow Times has written at length about this).

While the majority of the carriers operating this aircraft today have an obvious interest in safety, the limitations of the design remain. There are of course some design decisions made with older Western aircraft, like the exploding 747 center fuel-tank, that perhaps weren't the greatest. There are also several American airlines that have made conscious decisions to compromise safety, such as Alaska and their (lack of) MD-80 maintenance, the lazy DC-10 engine installations, etc. etc...

Agreed. But this also makes me think of the (previous) faulty A330 engine installation design that led to the "Canadian glider" event. Yes, it happens...worldwide.

Haha, no. From what I understand it is a hose attachment to some pressurized air source. I'm guessing that there is either an air tank or a pump installed in the closet. I haven't looked and am no expert on this, I have just seen it on a plane and asked how it worked.
