I think there's a difference between being cleared to a certain point, versus just being asked to report again at a certain point.
But reading the above, I think I am less sure now what I would do in the case where passed from APPROACH to TWR and getting no response from TWR. Base legs are short, so not much time to decide and then retune back to APPROACH, so how practical is that?
But I would expect that there has been proper coordination between APP and TWR on our behalf if cleared into base leg... how unfair is that story told by Cat.S above!???!?
Q) What airfield has two TWRs? Is this Manchester or somewhere "oop north" that we don't venture too much from "darn sarf" here???
