A pedant requests... :O
The UK AIP contains the following note under the section titled 'Position Reporting within London and Scottish FIR/UIR' [ENR 1.1.3, 1.1.1 (note)]:
When changing frequency between any of the London Control, Scottish Control or Manchester Control Centres, pilots are
required to state their callsign and Flight Level/Altitudes only (plus any other details when specifically instructed by ATC).
When the aircraft is in level flight but cleared to another FL/ALT, both FL/ALT should be passed. Similarly, when the aircraft
is not in level flight, the pilot should state the FL/ALT through which the aircraft is passing and the FL/ALT to which it is
cleared.
Fair enough. I'm interested in the bit about the passing level. Do you expect a passing level on every handover within a controlling area (eg London to London) or does it perhaps mean that it should be given only when changing from, say, London to Manchester, or Manchester to Scottish (as this note might be interpreted)?
What do controllers expect? Is Mode C verification only required once per area? Is there more to it than just Mode C?
