I am looking for the callsigns of ATC upper information region (UIR) controllers on a flight from Frankfurt EDDF to Seattle KSEA. According to the flight plan, the UIRs crossed are:
- EDDV (Hannover)
- EHAA (Amsterdam)
- EGTT (London)
- EGPX (Scottish)
- EGGX (Shanwick)
- BIRD (Reykjavik)
- CZEG (Edmonton)
- CZVR (Vancouver) and
- KZSE (Seattle).
First, where can I find charts and information on the sectors within a UIR?
Second, does each sector have a different callsign, or are callsigns coupled to the UIR? For example, EGPX Shanwick will probably have multiple sectors, will the callsign be always Shanwick control? If they are UIR-dependent, what are the callsigns of the above-mentioned UIRs?
