I see the red arrows telephone number mentioned above.
I believe there is also one for royal fights.
I take it, that everything on these lines would also be included on the notams? Hence there is no need to ring them if you've checked the notams just before flight?
If this is not the case, is there an equilivant non-freephone number? If I were to make a flight from outside the UK into the UK, I coudn't access the freephone number before the flight.
