They were warned by training staff years ago this would happen with the A350 and it's worse than forecast
That's true for the 350, but everyone needs to remember that GL warned the adults (in a well written letter during SARS - so about a decade and a half ago) that we
will be short of crews in the future, and that every option to train as hard as they could should be explored. Needless to say, that opinion was soundly ignored. How many DFOs have had the chance to fix that issue??
