There's a good reason why NDB visibility minima are a mile or more.
You need to be able to see the airport when you get somewhere near it.


I don't buy that. If you can't see it, you go missed. If you can see it, you
land. Shooting an NDB with poor visibility may lead to more missed approaches,
and perhaps that's their thinking (why tempt a pilot into attempting an
approach that's likely to fail and leave him looking for his alternate) but
OTOH, this should also be trained into pilots, and then the visibility thing
becomes moot.

It might be that, since you will be farther from the airport, you need to see
more to avoid terrain, but again, you don't see the runway, you go missed.
