    JAL has never bought European? What about all those A300s I saw in Tokyo that they are now selling off for freighter conversion?

    What a wonderful ad. Heritage is an incredibly valuable thing and BA is right to use it to help promote themselves today.
    .

    Remember what happened to their heritage collection at Cosford?

    I disagree, and I know I am not the only one.
    Their 747 outwardly look fresh and magnificent in their colours.

    Inside the ones I’ve flown on in the past few years and very recently, they look tired and tatty in places. Cabin over haul needed as well for the 747’s perhaps?

    Presumably that is the Band Aid round the second and third windows. Wonder why it was worth restoring to airworthy condition just to have a funeral in another country?

    I think the area around the windows could be where the ice shield from the prop was. It’s in the right area. The structural fix is visible on the top of the fuse made up of external stringers by the looks of it.

    KLM seem to have their main handling area for F50’s at Norwich and so their parts reclamation/store/processing area could be there. Seems odd when they were produced in the Netherlands though.

    Icing certification requirements are discussed in the interim report (2) : here – 1.18.5 System certification page 60. Seems like ice should never build up on a pitot according to JAR requirements and Airbus design exceeds those requirements.

    The report does mention the failure of the probes though.

    Anyway, this is all drifting off the original purpose of this thread. It’s turning into a body function over distance competition and there’s a headwind developing.

    [QUOTE

    The pitot heaters usually run very, very hot, if you touched them you’ll burn your hands, but it has been proven that in severe icing conditions this heat will eventually not be sufficient to stop the pitots from icing over.
    So in all, not that strange that all sources would ice up, afterall they are all presented to the relative airflow.[/QUOTE]

    Absolutely, i’ve seen pilots and engineers scarred to that effect. It would be interesting to know the full extent of the icing conditions and the effects on pitots and their heating.

    So how does this even remotely qualify you to comment on what was happening in the air & what it was like for the crew up there? It doesn’t.

    .

    That’s all of us then unless we fly A330’s and have been in the same conditions.

    Are there any standby instruments on the A330? If so, do these readings come from an alternate pitot static source?

    If so, do they have an alternate anti-ice supply?

    Strange if all airspeed info was ‘corrupt’ due to icing.

    And, arguably, more efficiently (fuel burn, nav performance etc) as well even during normal conditions.

    Hmm, but does the FMC nav database communicate with the EGPWS system nowadays to prevent automated CFIT?

    Hmm.

    FADEC uses static pressure for example even for ‘core’ computations. Static pressure is affected by external fluctuations. Therefore, an external influence. Normal control law is derived from sensors from the aircrafts digital air data computers i.e airspeed, altitude etc. All external influences.

    Even using basic control law, ram air is a major influence on thrust produced no matter what state the control is on. You can’t get a much bigger external influence that the mass of air entering the inlet!

    EDIT: As an aside, does the A330 have standby pitot static instruments available?

    Deano – All true, my point I suppose is that technology has reduced accidents.

    Automated systems won’t stop accidents I think the inference was. CFIT was/is the biggest cause of accidents, no?

    Whilst EGPWS/TAWS isn’t so much automated, it has reduced these accidents hasn’t it? Which were perhaps a result of pilot error, no matter how experienced?

    I agree that I would rather have 2 experienced and more importantly, well trained pilots up front though. I never questioned that.
