Alexander,
As a general rule of thumb any thing more than 50% goes into resume pile two. Eg 150 hour TT 70 - 75 command. We go through logbook and look for how much time training has taken. The sort of training that has been done. We are looking for signs of struggle during training. Lots of dual time compared to command is an indicator we have found in the past to either lack of natural flying ability or lack of listening or understand skills.
We don't want to take the easy way of culling that a lot other operators use and just put a 300 - 400 hour minim on new pilots. We have always felt a sence of responsibility to give back to the industry that has been good to us. Someone has to get pilots to the 300-400 hour mark. However we only have a certain amount of time, money and patience in a small organisation to be able to get newbies to line. We cannot go broke trying to get newbies to line that lack enthusiasm or ability.
We look for pilots that have the ability to think outside the box and are ahead of not just the plane but operations. We have seen a link between those newbies that need to be told everything and high dual time. Lower Dual time pilots tend to be big picture pilots. Eg have always studied a step ahead of physical abilitys, understand aircraft systems before flying that aircraft. Have constantly asked questions of instructor/ CFI during training. Live, breath flying and don't really look at flying as a job. Will arrive at work/training with weather/notams and flight plan in hand.
Have the ability to have a picture in their head of what the day will hold and changes that could happen before they start the day. I find that then helps them cope with the forever changing day that is charter operations.
Newbies tend to think that flying is the only skill they need. Organisation is just as important and that tends to start in training and will also show in Dual time.
Hope this helps
Mick
