This is an interesting topic – hate to see it die without generating more inputs.
Do any Operators provide a specific S/E Procedure from a runway to a weight – then if the weight is exceeded, provide a different procedure?
Do any Operators provide a S/E Procedure with optional procedures within that procedure – that is either go to X Intersection and hold, or if above an altitude (or some other criteria) accept vectors?
I think most here have implied that they would not accept vectors from ATC if there was any doubt as to whether it was based on anticipated performance of the A/C, by ATC – that is in the direction of obstacles not yet cleared. On the other hand – many have pointed out the absurdity of going to a holding pattern when you should be heading downwind for a landing – or worse yet driving into a bee’s nest of traffic when a safer course is evident.
The issue of whether ATC does know – or should know about these procedures - is another interesting question.
