HANG ON A MINUTE.........,
1 - As has been pointed out already, this is an EU directive, not legally binding in the UK. Suprisingly,(or not), only 50% of such directives are adhered to straight away by the Government, lets hope that this is one of the 50% they ignore.
2 - Whilst Heathrow may have some restrictions placed upon it, this is because the BAA could not prove the economic necessity of having these flights at the those times.
The vast majority of night movements at other airports are economically necessary, ie night mail, parcels and urgent freight, passenger flights which cannot be operated at any other time. Therefore the likes of EMA etc are likely to be unaffected.
3 - There is, as I understand it, no UK legislation which is binding with regard to noise caused by transport.
Even if you discount the above, the political fall out of UK regional airports losing vital night trade, and therefore the whole regional economic infrastructure being affected, would be too much for the local politicians and the government to face.
