Hey everyone,

I'm in the midst of working on my IR here at Purdue, and while looking at some local non-precision approaches, I can't help but wonder - to put it bluntly - why the Missed Approach Point is at the beginning of the runway. I'd think that one would have to be quite hopped up to consider starting a descent through the MDA over the numbers...

Instead, consider the fact that Visual Descent Points ensure a normal 3-degree glide path from a specific point along the MDA. Wouldn't this be a more prudent choice of location for executing a missed approach? Clearly, any point beyond the VDP would require an increasingly steep descent to the point of absurdity at the threshold.

Any and all comments, clarifications, and corrections are greatly appreciated.

Thanks,

Brian
