What i forgot to say, which is nearly all the news stations favourite line at the moment, "..and it is the same type of aircraft that was in the recent Air France disaster which killed over 200 people..." or something catchy along those lines...

But you see, that's only filler until the unions come out and say that the fault was due to having maintenance check ups in Manila...

They will only 'pop' if excess current is being drawn through the circuit. Just because there is an electrical fault, doesn't mean excess current is flowing through the circuit.

Whatever happened, it is a very rare occurance and just unfortunate timing. Well done to the crew for their professinalism in handling the situation.

If his facts are facts then how can they be wrong?

Next year is 7 months away, that's plenty of time for something to go wrong...

Question Flames + oxygen?

What is the procedure for oxygen use when there are naked flames? Obviously with smoke you need oxy masks but is there an issue with the use of oxygen near naked flames?

And what kind of fire extinguisher is carried - on the assumption that any fire will most likely be electrical, is it CO2 or powder?

Aviation has an exemption to use Halon fire extinguishers which are extremely effective in the aviation environment.

Oxygen masks would be used after it has been discharged in the flight deck.

You would try to keep oxy away from a naked flame obviously, but if the masks need to be used, then you'd use them.

For a fire in the cabin, you would remove any nearby oxy bottles to ensure you don't flame the fire.

Question Communications during mask use

The JQ captain has [reportedly] stated that he could not tell passengers what was happening because he was wearing an oxy mask.

Does that mean that flight crew can't communicate at all whilst wearing an oxy mask? It doesn't sound right to me.

Philip,

Yes you can make radio calls/announcements while wearing a mask.

Whether you would want to make a PA while wearing it would depend on the urgency of the situation, as the "Darth Vader" tone do your voice may cause undue stress to the passengers when there is no reason for them to be overly concerned.

Really depends on the situation.
