Where were we? Who knows! On a green line on the nav display :-)
To be honest, once the practice pan starts I turn the volume down since we were talking to London and starting our descent. I can't remember exactly but I think we were on a Lambourne 3A arrival to Heathrow probably passing through about FL300 off the east coast. We get through so many sectors in a week that it's all a bit "Groundhog Day" so recalling the details of any one approach is well beyond me.
