Clearance - Controlled air space?
I always used to reckon the class D Controllers preferred to keep us lot out – particularly from the busier control zones. This was largely a perceived impression. My experience, although not wide, is different. Solent is excellent and so is Gatwick. Luton are also very cooperative and even Stansted do their very best? I wonder on others experience, particularly of zones not mentioned. Also what specific problems have people encountered “negotiating” that zone clearance that may save 20 or so minutes of flight time?
