and which may confuse the heck out of an air trafficker unused to such things.
Which would confuse an air trafficker more:
- An aircraft reaches an airways point, requests to leave controlled airspace by descent and then, a few minutes later turns up at a VRP asking for VFR entry (both completely normal, recognised aviation practice) or
- Aircraft flies a STAR, arrives at the IAF and says "sorry guys, here I am in the middle of an IFR procedure but I'm VFR and can go no further IFR; what are you going to do about it?"
The answer seems obvious.
