Obviously it won’t be a full new hire ground school, but it’s also possible between paperwork/docs/blue propaganda and benefits/etc it may be more efficient to run a short in person indoc. I would imagine NK pilots would need some form of sim PC check with B6 procedures to fly on their operating certificate. Seems like 3-4-5 days could handle all this and could be done anywhere with a sim, and fly out some HR people.
