As more details came to light on this situation its not quite the bad situation as i initially thought, that being said a BS service whilst using instument procedures
is open for misuse and a very slippy slope if not correctly managed i believe
Economics has never influenced my decision to the extent i have fudged it to solve a ATC problem. As the book says "safe, expeditous flow of air traffic" etc. Safe comes before expeditous for a reason and there is no pilot out there who will come to the subsequent inquiry if you fudge and it all goes pear shape to defend you because you were saving him fuel.
