I haven't instructed in a long while but it seems to me that when a person is learning a new skill you can't always do adhoc lessons. Each lesson has to be taught chronologically in order for all the pieces of the puzzle to fit. This post brings to light something that many of us already know. Winnipeg Area and Winnipeg tower are the most un-accomodating atc group in Canada. They are not a pleasure to work with at all. Quite often a reasonable request is rejected promptly and in a curt "I'm annoyed" tone of voice. Other centres especially our US friends will provide a reason why the request won't work. That in my mind is good CRM on the controllers part. I wonder if our YWG counterparts are clutching to their bureaucratic past instead of their new reality of being a service provider.
