As you are so situationally aware, wouldn't it be better when you are at the 'expected point' to give a call to say you are changing frequency? Surely you don't leave everything for ATC to do for you
Better to have dialled up an ATCU you are flying towards, than one you are out of range of and flying away from
This may not be a good idea and could even make matters worse. It may be that you have just been transferred to a control sector on a different frequency to the one you have just disappeared to. So the handing over controller you were with calls you and you do not respond. The frequency you have popped up on unannounced will try to work out what you are and who you are and why you are calling them and may have no idea where you should really go. Sectors are often 'bandboxed' together when traffic permits and may use different frequencies to those published. It's a lot simpler to just give a 'check call' to your current controller.
When/if CPDLC comes into full usage a lot of these problems will disappear as your CPDLC connection can be automatically transferred to the next 'data authority' - your next controller, without you needing to touch anything.
