Before I get a roasting from someone at CHC I should mention that the correct procedure for Flight ID is to set the callsign if a flight plan has been filed, if not then the reg. Its a moot point as to whether a flight plan has been filed since we are very unusual in Abz in not filing flight plans ourselves - ATC do it direct via the "mayfly" system. So I suppose it could be argued that as we don't file flight plans, the reg should be entered.
However, after discussion with ATC it was pointed out that it would be much more helpful if the callsign appeared on their screens (when they get them) than having the reg twice. That's why BHL and Bond set the callsign, and the likes of Inverness, who have mode S, can then see it.
Just another example of the widely differing operational ideas between the different operators, albeit a fairly trivial one.
