Can you tell us exactly what indications are there in the cockpit when a duct bursts, other than a slight loss of thrust, which I assume the pilots might feel? Are you saying that if a duct bursts (even a little burst) there will be an appreciable and noticeable decrease in thrust and there will be a warning in the cockpit?
And are you also saying that, if a slight decrease in thrust IS noticed, the actions for that are to shut the engine down?
Even if that were the case, and even if it was during your own 'worst case' scenario, surely there is a serious risk of fire/explosion immediately the duct fails or leaks, especially during the take off run?
Wouldn't it all be a bit too late then?
And as for saying the QQ are NOT Nimrod experts, I can't disagree with you, but may I ask who you believe are the experts on this subject?
Thanks
