New approach format
All,
Researching a new (at least to me) charting format used in YQR. Specifically for the RNAV GPS 13 and 31 approaches. The approaches are new in design and have charting material I've not seen elsewhere. They mostly follow the T pattern, with the addition of a charted .2 prior descent point along with shaded altitude on the final approach course. The approach looks like it was designed with a constant descent profile in mind rather than the chop and drop NPA procedure.
What I'm looking for is any documentation that fully explains this new format. I looked briefly at the Canadian AIM, but it didn't touch on it. At least in the area I looked.
Any help is appreciated if there are other documents publically available I can look at.
Thanks
