F&T - I have re-instated your post (and taken out some of the chaff) . It upset a sensitive 'Virgin' which is why the title was changed - and I hope the new one is better.
I hope you have learnt a little about how to post your query on PPrune and a little more about aircraft operation. NB the way to post shorter links too.
You may not realise it, but a 'full scale emergency' probably refers to the ATC classification of the event and not to the flight crew's reaction. You can read all about ATC 'reaction states' on PPrune too.
