1500 hours min. Pref with 500 hours on a JAR/FAR 25 aircraft.
Spoke to 1 of your LTCpt about 3 weeks ago and in his opinion once NJE will start hiring again JAR23 (i.e. Kingair or similar) would do fine.
Usually folks have a LOT more than that. Typically 3,000 hours +.
Another guy (FO) told me 2 days ago he joined with less than 2000TT (18-900-ish) and knowing a Cpt. took his CV at the top of the pile.
Right or wrong we all hope this downturn turns UP again SOON!
