As I am on the take-off roll, at 100 kts, and I hear the tower transmitting to an aircraft to "stop."
You're assuming the aircraft involved would be on the same frequency at all times. More often than not, an aircraft crossing an active runway would be on ground freq. Are you saying that for the sake of situational awareness all YYZ traffic should be on one frequency?
And I think that while you obviously put a lot pride in your situational awareness and that it must indeed be a pleasure to work with pilots like you (no sarcasm here) since you do try to get the big picture, the majority, like the EGF crew, aren't aware enough of their surroundings to get an added value to having only one language on the freq.
I apologize for the confrontational tone of my original post. As I do work in a bilingual environment, it's something I'm intimate with and I see so much lack of SA from aircrew that, to me, the one language thing is but a drop in the bucket of flight safety.
