On A320 once we had to use the bottles for the rear hold during cruise. Fortunetly it was a false warning. To my surprise returnflight according MEL was o.k. even with hold loaded (no flammable stuff).

The -400 MEL does allow dispatch without hold fire suppression as long as the holds are completely emtpy.

Assuming no obstacles, no passengers and no freight/baggage the -400 would have no problem at all in using a 2400m runway.

Some MEL's are a bit unclear.

If cargo fire systems are inop (apart from a single loop fail), hold needs to be empty, because most items can burn.

Another point, if cargo door seals or cargo linings are less than servicable, hold needs to be empty.

JumpAhead 17th Apr 2006 16:45

The fire detection system draws air from the holds over 2 "loop" smoke detectors. Smoke needs to be detcted by both loops before a fire warning is annunciated.

Note this system is not using the hold temperature to detect a fire although the temperature can be viewed on the EICAS ECS page by the flight crew.

If one of the smoke detector "loops" is faulty, the MEL allows it to be effectively locked out and the aircraft dispatched normally. In this case only one detctor needs to detect the smoke to trigger a fire warning.

If both smoke detector loops are faulty or the fire extinguishers cannot be fired for any reason, then the holds must be kept empty.

At least that's how I understand it ....................................

That's what the airbus MEL says (two bottles):

Both may be inoperative provided flammable or combustible cargo is not carried in the affected compartment.

So BOEING is more restrictiv.

JumpAhead 17th Apr 2006 18:22

Tricky to know that there is nothing flammable if you have 20 tonnes of cargo/bags in ULDs and on pallets!

Than you should have received a NOTOC.

JumpAhead 17th Apr 2006 18:38

Agree a NOTOC should be supplied for notifiable goods.

Just making the point that anything in the hold poses some risk .....

Last time I looked in an "empty" hold it was full of rubbish such as old bagage labels, bits of tie-down rope etc. I think there was an Air Canada 767 a number of years ago that had just such rubbish set alight by a faulty water heater mat. Fortunately it happened on approach.

Sure, but please correct me, sticking strictly to airbus MEL, carriage of luggage would be possible in this case.

Joetom 17th Apr 2006 18:59

Think you can get water to burn in the right conditions.

Many aircraft have operated with inop fire systems and items in the holds thinking it complied with the MEL.

Hold should be empty and clean.

What - worse than St Petersburg ? :)

Must be a feature of old Soviet runways.

Yes you may be correct as I don't know the Airbus MEL. However, I would class passenger luggage as combustible. As to an ignition source, well who knows what's in their bags! Ever seen the firefighter demo of a bit of wire wool and a mobile phone battery?

Personally I would be reluctant to depart with anything in the hold that could burn if I had no way of putting it out.

WHBM 18th Apr 2006 12:37

Now that this one seems to have died down, can I ask a genuine question to the ops people from BA writing above.

Did you feel it really was the most effective way to handle things, to do this recovery with your own aircraft. Interesting to read all the convoluted arrangements described above, and the apparent urgency to get the relief aircraft out to Uralsk.

But would it not have been more effective to have chartered a widebody from one of the several Moscow charter operators ? Much of their capacity seems to hang round the Moscow airports waiting for business, and they know Kazakstan. Could be in Uralsk in 3 hours, and then hike everybody over to London. No problem on an Il86 with lack of steps, they have airstairs to the baggage level and a staircase inside up to the cabin.

renfrew 18th Apr 2006 13:10

Yes,but can Uralsk take a IL-86.Someone mentioned that a Boeing 757 is normally the largest aircraft there.

Althouth I'm not BA ops but based on my extensive experience of handling similar things I can tell you a few problems in your scenario:

1. Insurance. Russian carriers (excl some majors) have a different insurance policy and even then it is hard to get any compensation. If something happens it would cost BA a fortune in lawsuits.
2. Service standarts. Most of operational IL86s are deployed on charter routes and in a pretty sad state inside. If someone think that *unnamed* G-registered charter 767s are cr@@ inside they never seen Russian charter planes.
3. Believe me - the realistic time take to get IL86 airborne from Moscow is 12 hours or more from signed contract. IL86 operators are not specializing on a short-notice business.
4. IL86s are banned from Europe due to Stage II anyway.
5. Potentially there could be some passengers onboard who cannot travel on Russian airlines apart from a few majors like SU or UN due their corporate insurance policy.
6. It is usually cheaper to fly your own airplanes (if availability and timescale allows) than chartering someone else.

On the other hand there is VIM Airlines in Russia operating a fleet of 757s (tight charter config anyway) who are normally quick to react and there is Transaero with ex-Virgin 747s and well known for changing the planes assignment between routes on an hourly basis :). One of them or combination of them may work but introduces some problems and uncertaincy anyway, let alone the cost, so from my point of view BA ops did it in the right way. :ok:

It's been stated that the aircraft landed in about 30 minutes. Is this typical? What would have been the situation the warning had happened when over Siberia, Pacific, Northern Canada etc.

I'm not sure what your point is - I guess the answer is that elsewhere, in the abscence of any indications of a genuine fire, they would not have landed in 30 minutes.....

Buster Hyman 18th Apr 2006 22:12

Perhaps they landed in 30 minutes because they could land in 30 minutes. If it happened in the places you mentioned, I'm sure they would have gone for the closest suitable strip & failing that, perhaps ditched, or landed anywhere possible...makes you wonder though, what would the thought process be for a possible fire & no immediate runway available. Would you ditch or aim for a long road? Would you confirm the fire before taking such drastic action?:confused: :confused:

wiggy 18th Apr 2006 22:18

Buster
 
Agreed.
IMHO you run for the "nearest suitable airfield", be it 30 minutes or 180 minutes away...in any case you keep an eye on hold temps (EICAS) and floor temps (heavy P2 standing on the deck, shoes off :} ...cue "the boy stood on the burning deck etc"

If, god forbid, you get signs of a real fire then the Captain is going to have to make the Career defining decision....

sixmilehighclub 18th Apr 2006 22:29

An incident occured, the Captain made his decisions (correct ones in my eyes) and other parts of the BA team, be it management, ops, crew, etc did their part to ensure everyone got home, safe.
