We are reviewing any and all specific concerns. I think you're referring to Bombardier, which is the main manufacturer at the site, and Bell Helicopter.
In fact, before we changed to a flight service station, at the request of Bell Helicopter we did change some airspace to make it more suitable for them. In the case of Bombardier, we opened up another whole block of airspace northeast of Montreal for test flights, in addition to the one we already had for them northwest of Montreal. We are continuing that dialogue.
For the information of the committee, at this point we have found no difference from a safety point of view between the operators receiving a control service and their receiving an advisory service from the same tower by the flight service specialist.
I would add that it's important to remember that the main purpose of a control service is to prevent aircraft from hitting each other. It's not a service that in any way looks after the physical airport itself. It is much more related to keeping airplanes apart, keeping them from hitting each other, and keeping them from hitting vehicles on the ground on the runway. The flight service system works extremely well and has, as I say, an exemplary record for doing that.
