Can a real ATCO confirm whether (VFR FIS context) ATC really want to know the ETA to some WP?
I know that if you call up London Info and sound anything vaguely resembling a training flight, they will ask for the ETA to each WP, but I would assume they do that because the UK PPL training business gets every student to call up London Info.
I reckon that if you are flying from say CPT to MID i.e. past Farnborough on a nice Sunday, the last thing they want to know about is your ETA to some village. Do they really keep track of everybody with an FIS?
Especially if a pilot laboriously reads off half the local village names.
I fly through there often and all I do is tell them my dep, dest, type, the immediately relevant part of my route (always using VOR waypoints), altitude, 7000, VFR (or IFR if in cloud) and they happily leave me alone, giving me RIS or, if really busy, FIS.
