Let's say that during a VFR flight the pilot requests flight following from ATC, giving information about the aircraft type, type of equipment, destination and cruise altitude. ATC responds by giving a squawk and saying "maintain VFR".
In that scenario:
- Does the pilot have to request an altitude change from ATC during flight following, even though the flight is under VFR?
- Or, does he need to just advise ATC and start descending/climbing to another VFR altitude?
- Or, is it not necessary to say anything to ATC about VFR altitude changes during flight following?
Finally, where can I find information about the regulations for flight following? I could not find anything in the FAR/AIM.
