Megan,
If you have good Capts and a good training dept there is no need for a FO on a Metro/S340 to have 2000TT and 500 ME command.
Dragon Air take A330's with a 200 hour FO into very high workload Chinese airspace. Throw in some CB's and you have a party!
I can't for the life of me figure out why a Metro/Saab operator would need such high mins for the RHS. Apart from maybe they have a low cap AOC requiring 500 ME PIC for upgrade.
