| NEW True or false....? #9 |
Author: Anastasios 1346 Posts Status: Living Legend  | Date 09-04-07 09:20 |
A Boeing 747 does not have a ventilation system which can get rid of smoke in the cabin...
If there is smoke in the cabin and there is no possibility to land, there is only one way to get rid of the smoke.
The procedure is to open the forward service door (right door) and the aft entry door (left door) so smoke will leave the cabin.
A: True
B: False
Anastasios.

Hmmmmm.... 747 is an old plane.... I'm not sure thay had smoke in the cabins installed way back then and consequently didn't have any systems for removing it once they had enaugh of it....
I say TRUE!
And keep them coming!

I must admit i am not sure. I think it might be True.
If my mind serves me correctly, the procedure on the DC-9 is to open forward and aft doors to sweep the smoke forward and out of the aircraft and this
will also clear the smoke from the cockpit... and think the 747 use the same procedure but taking a wild guess here AND most importantly thats IF I
remember correctly. Therefore I can be totally wrong 
Thanks for the interesting question Anastasios and would love to know the correct answer on this one.

The procedure is to open the forward service door (right door) and the aft entry door (left door) so smoke will leave the cabin.
In flight? While there may not be a dedicated smoke removal system, opening the outflow valve and dumping cabin pressure is sure to get rid of it
quickly, the passengers just have to put up with the rapid decompression. I remember someone mentioned how the FAA should get rid of the life jacket
requirements, and instead put a smoke hood on board for each passenger, it would save more lives. So, as for your question, if on the ground, then I
say TRUE.
But, if in flight, I say FALSE. You aren't going to get the doors open unless the cabin is unpressurized, and the very act of releasing the pressure
should get rid of most of the smoke.

Wow, nice to see this many reactions!
Well, I'll give you the answer then...
The 747 is an old plane indeed... It is true that the 747 does not have a ventilation system to get ridd of smoke in the cabin. However, opening doors
inflight is never a good idea ofcourse...
But imagine....
Flying over the transatlantic ocean... it will take at least 3 to 4 hours to reach land... It is possible an inflight fire occurs, even though it
might be exitinguished, smoke is still in the cabin. Continuing the journey with smoke in the cabin is dangerous, if it enters the cockpit they will
have the worst visibility ever for landing. They won't be aible to look outside, but it will also be difficult for the pilots to read their
instruments. And ofcourse, the smoke is véry bad for your health...
Then the crew will have to make a choice... Continuing the flight with smoke in the cabin, ditching the airplane or try to get rid of the smoke in a
different way.
In this case the pilots will descend the plane below breathable altitude and with a reasonable temperature... Cabin crew will prepare passengers by
suggesting them to put jackets on and stow all loose items... As soon as the pilots reduced speed to it's minimum, cabin crew will be ready at the
assigned doors.
They will probably choose big and strong passengers to help them and with rope they will open the forward service door just a few centimeters as well
as the aft entry door (at KLM door 22 and 14 or15).
This is an official Boeing procedure.
Anastasios.

Ok!
Next question!
Situation:
One of the pilots needs to go to the toilet! If a plane has no camera so pilots can see who is at the other side of the door, they will need to call
the cabin crew first.
The youngest flight attendant (read: the one who is newest in the company) will replace the pilot who needs to go to the toilet. As soon as the pilot
returns, this flight attendant can open the door so the other pilot won't have to leave his seat, but will stay in control of the aircraft.
This flight attendant is called: the pee-attendant.
A: True
B: False
Anastasios.

On this one I will have to take a wild guess.
A flight attendant needs to be in the cockpit whenever a pilot leave the cockpit (for whatever reason)... altho usually for a toilet break.
I however have no clue about whether it is the youngest flight attendant and dont know if he/she is called the pee-attendant.
As the one part I know is true I will guess that the latter is also true and therefore vote TRUE.

I'd say TRUE as well.
Somehow I don't think it matters which FA is in the cockpit, but it would probably be better if the more-experienced ones would remain in the cabin
where they can be of more use in case of a crisis.

Due to the fact that "the youngest flight attendant" was mentioned not just any old flight attendant who happened to be close by I would
guess this is the point of the question.
So, I'm going for false and saying an experienced person would do the job not a new recruit.

Aaaaaand once again...
we are going pretty fast here...
I'll be running out of questions if we continue like this.
Anyway, correct answer is: true again.
(Ofcourse the 'pee-attendant' part isn't written in any book).
This procedure is written down beautifully... but it never happens... especially because most airplanes now have camera's... so the pilots can see who
is in front of the door from their seat and they can also unlock the door from their seat.
3rd question will arrive soon!
Anastasios.

Wait!..., I need to catch up first.... First one is True, second one is also True
Wow, I'm off to a good start 2 for 2.

Ok!
Next question!
Situation:
A passengers walks to a flight attendant to tell her that she found a strange device with a note in the forward toilet.
As the attendant takes a look she reads the note: 'BOMB ON BOARD'.
The note was located next to a strange looking device on the floor of the lavatory.
After she reported to the purser and captain, the crew started the procedure of handling a bomb on board.
After contact with ground specialists they identified the device and decided it was safe to move it to a safer location.
They followed one of these procedures:
A: Cabin crew removed one of the service trolleys in the most aft galley and placed the device in
the position of this trolley.
After that, the cabin crew collected jackets, seat cushions, pillows, blankets and bags to completely stow
this position.
B: Cabin crew attached the device to one of the aft doors with a rope. The cabin crew collected jackets,
seat cushions, pillows, blankets and bags and build a wall around the device with these items.
C: The device remained in the toilet as this is the safest place for the device as it is in a closed area. The cabin crew collected jackets,
seat cushions, pillows, blankets and bags to completely stow the toilet with it.
D: Cabin crew reseated passengers of the last 10 rows and placed the device on one of the seats or,
if it fits, in the seatpocket. The cabin crew collected jackets, seat cushions, pillows, blankets and bags and build
a wall around the device with these items.
E: A device that may possibly be a bomb may never be moved to another location. The plane will land as soon as possible.
F: None of these procedures are correct.
Make your choice!
Anastasios.

Oh I am stuck with E and D.
D = If the plane is unable to land quickly (transatlantic flight), then I would say this procedure is correct.
E = If the plane is able to land, then It should be done!
Great topic!

As its safe to move the bomb it should be moved to the location on the aircraft where it will do the least amount of damage if it detonates.
Therefore I think the location might vary depending on aircraft type. Stuffing jackets, cushions pillows etc around it to my knowledge are the way to
go as it will assist in directing the blast (if it goes off) towards the area predetermined where least damage may occur... usually an aft door.. and it should result in an outward explosion with the items packed around it limiting damage towards the inside.
Therefore I have to go with B on this one.
Once again very interesting questions and very informative... tx Anastasios

I can't see it being correct but B seems to have some logic to it. If it does go off whilst attached to the door perhaps the thinking is it will
blow the door out and leave the airframe (mostly) intact.
I'm going to pick E though. Not touching it at all seems the safest course of action.
