Its been reported that the Co-Pilot had 630hrs of flying time - is that Total Time or Time on Type? If its total time, which would be very odd indeed - what has he been doing for the last 7 or 8 years when that is typically what some pilots knock out in a year minimum?? Either way it looks strange to me!
Could be time on type or total time, the difference is at most 90 hours not counting his glider time.
Apparently he joined the lufthansa flight school in 2008, took a break in 2009 and returned after he was declared fit to fly again. At this time the economic crisis was in full swing and flight training was slowed down as much as possible. After that he worked in the cabin while he was on the waiting list for a flight deck position within the lufthansa group. In 2013 he joined germanwings as a student pilot and completed his MPL there (remember, the full MPL is only issued after the LIFUS phase is completed) and then continued to fly the line there.
