500hrs is not going to help that much, outside of radios. I think it may be a hinderance in some ways, having to unlearn what you have learned.
Wrong again my friend. I had about 600 hours civilian time and it helped me a lot. ESPECIALLY the instrument part of it.
Interesting how different MB and KSUFLY feel their civ flight time helped/hurt.
The numbers tell us that anyone with PPL or greater attrites from flight training at a much lower rate than everyone else. the numbers don't tell us why. My personal belief is it has very little to do with flight experience. Rather, I think it is because these are people who love to fly so much, they were willing to spend a lot of their own hard earned money to do it.
Anacdotal stories from IPs (mine included) suggest, when it comes to students with significant civ flight time (PPL or more), there are two types:
1. Those that think they know how to fly and don't think they need to waste their time studying.
2. All the rest.
Both groups tend to perform exceptionally well in Contact since they know how to land and talk and look around already. But, as those in Group 1 progress, performance degrades. As the material becomes more complex and moves beyond their civ experience, these students often are caught off guard by how much they now need to study.
There is also a subgroup in Group #1. Not only do they think they don't need to study, but they think they know more than the IP who is trying to instruct them. This attitude is not looked upon very favorably in the training command. Or in the fleet, for that matter.
In Primary, the Contact grades may very well be high enough to put students in Group #1 at the top of their class...maybe. But, maybe not.
I'm pretty sure that every IP will agree, it isn't so much the experience you bring to flight training that gets you the grades. It is attitude, willingness to learn, motivation, and desire.
