I'm planning to fly up to Oshawa Ontario next week (from Rochester, =
NY).
This will be my first flight there since I got my instrument rating. =
The
en-route chart shows an airway A21 going from the St. Catherines NDB =
to
Oshawa NDB. I have to confess that nothing I've read has ever said
anything about route planning with these sorts of airways (Alpha?). I =
was
thinking that I could do ROC v31 AIRCO v252 a21 OO, but there is no
defined intersection point between v252 and a21, so I'm not sure how =
the
ATC computers would handle that. I'm sure they don't want me to go =
all
the way into to YYZ and back out.

I figure in the real world I'll probably get direct OO long before I =
get
to that point, but I'd rather file something that won't get me a full
route clearance.

It'll be interesting to see what you get, Paul. Be sure to tell us.
I'd say be prepared to go direct OO from about the BILGE intersection.
In fact, I myself might even file it that way, in anticipation.

If you really want to file to that unnamed intersection of V252 and A21,
notice that it's at N43 29.2 W079 06.1,
or that it's also described by YYZ124025.

Same as you, I doubt they'll want you penetrating the YYZ Class-C area,
but I suspect they'll get you inside the Class-B area before going =
direct OO.
However, my record at out-guessing ATC isn't very good. :-(
I've received some very circuitous vectors going into YYZ in the past,
but it's been quite a few years since I've been there, so ICBW.
