minimum requirements for Metrojet for F/O are in the region of 3000 TT and 500 Jet.
An F/O at Metrojet on 550 will average 200-300 hours, could be more could be less. No real set schedule on any aircraft.....thats corporate life!
Your mate, who was dispalced, if he has 200 hours, i assume a CPL/IR, he should target Cathay, Dragon, HK Airlines, Hk expresss, HK GFS etc, no one spends 45 Million on a biz jet, then hires a 200 hour rookie to ploe it around (unless its the owners son).
Hope that helps you.
