when was the last time you used procedural CONTROL
Okay, okay!
February 2000. Kimberley sector, Tops Group. TCTA/OCA, no radar for an airspace that would swallow up the UK about 20 times, with 10 min longitiudinal routes and a boundary that abutted Melbourne FDRG, Jakarta, and Bali. Half the airspace I had VHF comms, the other half was OCA with HF (third party provided by Ausfic) or CPDLC.
Satisfied??
I don't miss the Tops doggos.
