what hours of operations a [MATZ] might be open in case your examiner asks you to transit across one
I wouldn't get too hung up on this one, they often don't keep to the published hours, particularly if the Americans have decided to start another war that weekend. You're supposed to give them a few minutes notice, which is plenty of time to get your three calls in, and if they don't answer just carry on.
I've
never planned a route round a MATZ. I have on occasion been asked politely if I would mind accepting vectors ... the
really polite ones then tell you where you are when they've finished with you!
