Re: News about early 2014 schedule
^Let's keep in mind that, going by production order, Chekov was introduced as an assistant science officer, and wasn't seen at navigation until his third episode.
You're right. But that doesn't explain how he'd have been trained on the new design by the time TSFS rolled around. I'd guess he had a chance to learn during the ship's second five-year mission before leaving for Reliant
, but it's not clear. Chekov seemed to bounce from station to station depending on which film was taking place (tactical/security ----> XO ----> navigator ----> science -----> navigator).
