I have been through Leuchars matz a few times, including on my flight test and I have always been given a “clearance” through their overhead. Bit of a nuisance if you are heading to Fyfe as it makes it a bit of a dogleg from the Broughty Castle VRP. I would reiterate the advice given above to listen out for a “height”. Nearly caught me out the first time but Leuchars is almost at sea level anyway so not much difference. Other MATZ are available with different Amsl.
