Approaches in Canada

[PappyJ]

First of all, I'll agree that I may be misunderstanding your post a little.

That said, Jepp; Canada Air Pilot; NOS; Navtech; Eurochart; and all the others are "Chart Publishers," not procedure designers.

All the chart publishers (worldwide) publish charts with the details provided by the respective authorities (usually published in the that country's AIP and supplemented by Notam, etc).

Between the publishers, the differences are in the format only, not in the respective procedures. Obviously, Canada Air Pilot does not produce charts for airports outside of Canada, so the foregoing only really applies to Jepp, Navtech, etc.

None the less, the authorities design and certify approaches and procedures. Chart publishers simply assemble the data into their respective formats and publish the charts.
