Thank you for the question.
We talked about it a little bit earlier on pilot production. The air force currently is responsible for 26 trades inside the bigger Canadian Forces package. Of the 26 trades, we have seven that are still under stress. We define “under stress” as being the trades that are 10% short of the preferred manning level.
That's better than last year. Last year, we had nine trades in stress. We're down to seven, and that trend is improving fairly rapidly. My sense right now, assuming conditions don't dramatically change around us, is that we will see the air force by and large being in the green as far as trades are concerned within the next three to five years. The pilot trade will probably remain a stressed trade because we have to make up for the gaps that we've had over the decades, and also to make sure that we can still produce and adjust for any sort of attrition that may be driven by the economy.
I'm fairly confident that we will close the gap on those remaining trades. In the pilot trade, we're okay. We're going to produce as fast as we can. Right now, I don't have any undue concerns about our being able to hold the line on our current production. We've improved a lot of our processes, which allows us to produce folks faster, and have had great success certainly in the trades. Our aircraft technicians used to take three to four years after coming off the street before being able to fix airplanes and sign for the work they did. We got that down to two and a half years, which is a tremendous improvement. We did this through technology. The use of the virtual world has helped us move things along a lot faster. We're very satisfied with where that's going. We're going to keep looking for those increased efficiencies, but by and large, we're doing okay.
The biggest issue we will have is a bit of a demographic issue, which a lot of the services and departments face. We have a fairly young demographic. Over 40% of the air force has less than nine years of service, and we have a fairly large proportion of folks in the older demographic, let's say with 20-plus years of service. We have a bit of a shortage of folks in that 12 to 20 years of service bracket. That was due to major adjustments that were done in the mid-1990s as part of that decade's worth of economic adjustments that we had to make. We're feeling that demographic pressure coming through right now. Part of our challenge is that we're training a lot of new, keen, and smart folks, but the mentorship piece is a bit of a challenge, as we have to keep distributing the experience that we have in that middle crew to those eager young folks who need to be mentored and developed so they become solid air force members.
You know what? We've deployed on operations, as they say, across the world with those young folks, and they've done tremendously well. The training we provide them has certainly served them. Again, we call them our pipeliner veterans, because they've been out there doing the business and have done it extremely well.
