As to way our training system works, there is a basic selection that occurs, where all pilot candidates have to go through a filter to ensure they can learn at the speed required by the air force so they can go on to the other phases of pilot training. Everybody goes through that phase. Then there's a streamed process where they go to propeller airplanes—turboprops—and are trained in the most advanced flying and started on the road to competency. Then they are streamed off to either multi-engine aircraft, helicopters, or fighters. So there's a streaming effect that occurs shortly after that primary flight selection, and then they specialize in flying helicopters.
We don't see a bigger drain on the helicopter pilots than on the fixed-wing pilots, and their becoming commercial pilots. We've always had attrition based on the commercial draw, because we provide very highly-skilled folks. They have to give service to Canada first. They owe us several years of service before they can be released. Clearly , we want to retain those folks, because at that point they have a lot of experience that we need to leverage.
We're always looking at our system to see if we can optimize it. Our training modalities right now have proven to be very good and of high quality. As we get more demand to produce more pilots, we're looking at creating different streams to accelerate some of that training, but we're not there yet. We're satisfied that what we have right now is top-notch, but it depends on production. We may have to look at other models in the future to see if we can accelerate some production.
