Last night i came in Via the RIC4 ARR, Approach never said anything about calling the TWR with an estimate, so i didn't bother, TWR never said anything when i called them inbound.
So i'll be continuing as normal until i'm told otherwise.
But what a bloody shambles it was when i departed earlier on with everyman and his dog trying to get there estimates in, at the same time as the kaos with the temporary restricted area at Cabramatta.
From the tone of the tower voices, i don't think they are enjoying these ridiculous procedures either.
