To be honest, by surfing on the major pilot jobs websites, I'm still finding loads of DEC, with the common requirement, of course there are also others, not only the hours.
But, on the other hand, it's not said that just having 500h means to land the job.
OT: do you think that experienced flybe pilots are wishing to stick to the dash 8, not taking another type rating in major airlines, like an Airbus or something ?
