Yes it is sometimes possible to upgrade quickly at an airline, but it’s not common practice, and it’s after a good deal more flying plus sims. It’s not the same as a cat1 with a bit of T-6, then sims then RAG flying with a new aircraft commander.Not always so. Like here Captains can check out in just a few years. Depends on growth. If most ab initio guys go on the line with 400-500hours, they have to log another 1000 or so to get an ATP, or whatever their country requires. That should take at least 2 years.
