The main feature of my local airspace is Toronto Pearson’s (CYYZ) Terminal Control area. It looks kind of like an upside down wedding cake, each layer representing a different altitude. Below that altitude you are ok, above it you are in their airspace and jockeying for position with the big boys.
Confused?Good you should be! No one said this was easy
On my VTA I’ve marked YYZ and YTZ, you can see the dark blue circles which represent the layers of the wedding cake. The inner ring goes from surface to 1700ft, the next to 2500ft then 3500ft. But you can also see that the “rings” aren’t ring shaped! Because there are so many little satellite airports in proximity, even the messed up airspace is messed up!
Ok enough about the big bully that is YYZ, let’s look at YTZ. Zoomed in picture here shows City in orange with its control zone around it. Normally control zones are 10 miles across and circular. This one is neither. That’s because of the green, red and purple zones butting onto City. Respectively Pearson, Downsview and Buttonville. All of these are control zones that require, at the very least, two way communication before you enter them.
To anyone then it becomes very obvious that my only escape from these zones is to the east, that is where our practice area is located and that is where LOCALFLIGHTEAST spends the majority of her flying time!
