Sorry to bring this thread up again.
I find CAP413 missing a few things that may help us pilots.
If asked to contact say "Heathrow Tower". What is required as an initial call?
Is it just "Heathrow Tower, Big Bird One" ?
I hear a lot of people say "Heathrow Tower, Big Bird One Established on the ILS 27R"
Which one is correct ? I cannot seem to find a reference for it.
Thanks
