If the Hudson corridor is a VFR corridor, under, but not included, in Controlled Airpsace, why is ATC even invoved after the clearance to maintain VFR over the Hudson not above 1,100 ft, has been issued and acknowledged ?
Should an ATC operator hear an exchange between two pilots on a common broadcast frequency, that might indicate a conflict, then of course one would expect them to try to interject, but this is not a 'flight following' route - or is it ?
Surely ATC had little interest in the progress of the Cherokee, except to perhaps expect a call clearing the corridor, and a request for further clearance at that point ? Are VHF pilots required to give an ETA for the corridor clearance, or can they undertake any activity they like, for as long as they like, within the zone, below 1,100 ft ?
Sorry about my ignorance of detail, but it would appear to me that ATC have absolutely no responsibiity in this case if a clearance to transit within the parameters laid down has been issued ?
