The A330 isnt having a good start to the month. Good ? although, how does a cockpit window catch fire.

Neither is Jetstar!

I'm guessing it could have something to do with the cockpit window heat, they have been known to malfunction. I've heard of them cracking the glass, but never catching fire; it surely wasn't the actual glass that was on fire right!?

Jaysus! Not a great year or so for Airbus!

Maybe these type of things happen all the time and it's just because of the recent incidents that all the other minor mishaps start coming out of the woodwork?

arghhh, when 777 have emergency in LHR, then few engines shutdown(AF on TATL, in Moscow), smoke BA in Africa-no problem. Please avoid double evaluation.
Airbus will crash, especially 320, as near 5000 built, and statistically they are going to crash. Same with other Airbus aircrafts, same with 777. Thats life...

Cockpit windows on larger aircraft are laminated from layers of glass and plastic (acrylics and poycarbonates). They are heated so that they not only freeze or fog up, but also to maintain their flexibility which makes them able to better absorb impact - e.g birdstrikes, whereby the glass will shatter, but the plastic layers will hold things together. Heating is achieved by passing a an electrical current through a very thin, transparent coating of metal (typically tin oxides or gold) or small near invisible wires in a grid between the laminations.
So an electrical short plus plastic can equal fire, although its the first I've heard of this happening.
De-lamination due to the breakdown of the heating elements is a very common cause for replacement of windows after a period of time.

As much as I love freedom of expression, I would like to see some proof to back up your statement. wink.gif
