Here’s the scenario: Departure frequency is following your flight (i.e. no vectoring instructions). Departure hands you off to the center frequency during your climb. When following a filed FPL, what’s the proper pilot callout to the center frequency? I have been using “request flight following to [destination].”
I’m seeing pilots (of varying experience levels) request radar vectors or call or check in “with you at XX feet” when in the same position.
