At the recent interviews for Fokker F/O's, applicants were turbine experienced from other PNG operators. They were told they would not be considered for command upgrade until they had 3000 hours on type.
So 5 years on B scale to get a command on a 30+ year a/c that hardly anyone else operates with deteriorating work environment.
Story is that some are considering the offer and after 500 hours do a bolter with some jet time under their belt.
