previous clearances and restrictions still stand after a change of frequency.
Ok, but could someone give me the manual reference that states this please, as that is what I need to refer pilots to who ask me, or when I do a check on them and they don't do what they are supposed to! I know that a cleared level/ altitude still applies, it's the restriction that I specifically need to find the answer to.
Can you see the problem, all I can get is what people tell me is the right way, no definitive manual reference! We used to have an ATC liaison pilot (sadly the role has gone) and he was adamant that NATS were telling him that the restriction HAD to be restated if it was still to apply.
The thing is that reducing fuel burns is (rightly) becoming a hot topic and as a company we are exploring every avenue to potentially save a few kgs here and there and this is an issue which has come up.
Cheers
