<<Staying on APP freq at 6 miles is just as silly as me asking whether we need to be on Tower freq. At 6 miles I am on the LANDING phase not the APPROACH phase.>>
I only just saw this thread.. all very sad. However, to Dragon69... your perspective of the situation may vary greatly with that of ATC. There is nothing remotely unusual about an aircraft still talking to Approach at 6nm. I spent 31 years as a Heathrow Radar Contoller and kept thousands of aircraft until that ranage, and well inside that sometimes. Under certain conditions, eg SRAs, Visual Approaches, APP may retain control until much later on final, even until after touchdown. Technically, radar may be responsible for spacing on final approach and not the tower so it is entirely up to the controller and not you when he transfers you to the tower.
