I know this is probably a dumb question, and I think I know the answer to this, but I'm trying to understand WHY it's the answer. I suspect that the answer is: "because TERPS can guarantee obstacle clearance this way" but I don't know that for sure.
Take a look at procedures for YKM....specifically, the GROMO FOUR departure. GROMO FOUR
Each of the runways requires a climbing turn to GROMO and then you fly the appropriate transition, or, if you want to go southeast, you fly the arc to something like OHAWY and then SUNED.
What I'm not understanding is why, if I want to go southeast, I still have to go to GROMO and then fly the arc? The altitude required is 6300. If I can climb to 6300 before GROMO then clearly I can make 6300 before OHAWY, intercept R-108, and fly that to SUNED.
Is this because the only way they can guarantee clearance is to get to GROMO at 6300 FIRST, and then fly that 9nm arc? It seems like - especially if I'm taking off on runway 9, it would be simpler/less maneuvering to pick up R-108 and then proceed.
I'd appreciate wiser/more experienced thoughts on this. Like I said, I think it's because TERPS probably ensures clearance this way, but I'm wondering if that's the case or if I'm making assumptions.
