speedrestriction;
I guess it would depend on where those hours came from. According to the Ops Manual, a DEC needs 3,000 hours total, containing 1,000 command hours on a jet / heavy military turboprop (i.e., not the dash)
If you joined as an FO, upgrade occurs after a minimum of 12 months with the company, a satisfactory training record and 3,000 "factorised" hours. EG, every hour that is flown in house counts as 1.1 hour. External hours on type count as 1 hour, external non type jet 0.9, external turboprop 0.75, bugsmasher 0.4 hours.
Depending on base / fleet you could expect between 400 and 700 hours per year once you've joined. (737 flies more than 757, LBA and MAN fly more than other bases.)
