Old Smokey,
I like the idea of a generic EOSID for "general" issue, reserving the right for the bigger players to also create their own more specific charts for various reasons (including payload of course!).
As a first step, however, would it be fair to say that the aerodrome operators should be required to be able to supply, quickly, the required detailed surveys that are necessary to generate the procedures?
It seems that a lot of this survey detail is just not readily available, which would certainly dissuade a smaller operator from being able to come up with plans quickly and efficiently.
Question the 2nd - Do your airlines share their E/O SIDS and procedures with the local ATC's? Obviously some places in the world its best to keep the trap shut as more info would just cause confusion, but there are plenty of ATC departments who I'm sure would be interested to know roughly what we plan to do, before we actually have to do it.
