Getting back to the subject, the logbook column reads "IFR - Instrument Flying Rules", then divided into two parts "Actual" and "Hood".
As goldcup mentioned: "Mr B- Crossing the pond you most certainly were IFR. You may have had VMC, but you were under IFR."
When you're flying on an airliner you file an IFR flight plan. And you fly accorfding to those rules even when you are on VMC conditions...
Anyway, this was the question that's been bugging me for a while. I know perhaps it's not a big deal but wanted to ask/share...
Thx to all who replied!
