A partial lock would be good. It's the idea of having—being able to change it if need be—some sort of guidelines and having a direction whereby everyone paddles in the same direction. That might be difficult in a federal country, especially with international affairs as well that come into conflict. But the idea of continuity is very useful because nowadays developing an aircraft program in the CSeries, for example, takes years. Developing anything takes years, so if you have changes of policy mid-term, it's very difficult.
If you have big changes, as in the case of the Concorde, for example—it may be off topic, but the Concorde was a great idea, supersonic airliners. Everyone was going to fly supersonic in the seventies and eighties. You had the question of pollution in the atmosphere, the idea of sonic booms over continents, the cost of fuel, and the oil crisis. It seemed like a wonderful idea and it hit a brick wall.
So you cannot predict what will happen, but the idea of flexibility, with the idea of having a direction where you're going, is very important.
