WIDEBODY
I have spent most of the past 25 years upgrading pilots to the Left Seat of a wide-body.The only criteria with respect to hours has been laid down by the insurance company, and almost without exception these are 5,000 hours total time, can be virtually anything,including helicoptor time (factored at 50%), but at least some heavy turboprop or small jet preferred, all F/O is okay, plus around 1,000 hours on the wide-body type itself (to gauge the pilots suitability).I have upgraded a few with only 4,000 hours , but these were guys with exceptional skills and knowledge and the insurer had to be consulted/case put forward.Never seen any issues, but a lot of other ducks need to be lined up in a row to complete the exercise.
