officer was in transition training to convert his Airbus A340 type rating also to A330.

The calculations were available in the form of Operational Flight Plan (OFP) printed at
17.41 UTC (co-ordinated universal time) when the scheduled departure time was 21.15.

departure airport Chicago O’Hare. For the destination airport Stockholm Arlanda there
was a forecast with temporarily fog and visibility 500 m in the morning between 06 and
