when given a MATZ clearence am i expected to contact the tower for the ATZ
Initial Contact wil be on the zone/LARS frequency (if published) or approach (if either of the two preceeding one's aren't). The clearance you will get (pedantry aside) will be for the whole MATZ/ATZ complex - no need to speak to tower.
I asked an FI and he said he thinks it does
THINKS! Am I the only one here who finds that a little bit scary
