Not sure how they work North of the border, but under NPAS the SOP is for the TFO to give dispatch & flt following a call when about to lift and also call 2 mins before landing. These are followed up by the despatch room 'Oop North'. There are also 15 minute Ops normal calls throughout the flight regardless of operating area.
I'd imagine any registered/recorded police calls will be in the final report, as will the more accurate GPS tracks etc. I asked the question last night, 'If one of the officers was to try and make a call on the Airwave/Scottish system radio but it didn't make the connection as is the case a lot of the time, would the attempt to call be registered'.
'Probably' was the best we could come up with, but only after investigation by the net operator.
