Being a low lander, curious how this works past the obvious answer of, no go. Say I'm departing some airport in CO, like Aspen KASE, and I'm unable to accept any of the SID's because the climb gradients are all higher than what I can safely do. I know as a part 91 pilot I can deny the SID, but what would happen at that point? Say I was a moronic pilot who just wanted to blast off, and said "na can't accept, can't do climb gradient", would ATC tell me to sit this one out, or would they give me some sort of vector to piece me through the terrain. Or again, along the same lines, say I'm able to do the Cozy 1 departure at KASE because the climb gradient only goes to 10,000, but the end of it dumps me out on an airway with 14,000ft MEA, and now my aircraft can't do that. What does the dummy pilot do at that point? I'm sure these are silly questions, but curious how a flight like this would be approached normally, or sorted out in the system by someone not really thinking.
