Half mil maps
'Current Chart'. With respect, none of the CAA charts published are current, not even the most recent, unless you update it regularly, which can be done by using the NATS subscription service.
I was quite surprised by the number of changes that get notified by e-mail. My chart would look a mess if I were to scribble them all on it.
Just hope I don't hit a mast that's been erected on a hill top after I bought the latest chart, I doubt it would appear on my ipad....!
