Old-school NPAs used to be of the Dive & Drive variety, being careful not to go into any shaded bits. We try to fly these as a CDFA nowadays for noise and fuel burn, but as long as your lateral taking is good, you can be high most of the way down, just don't go below MDA(H) - its a NPA after all. Set -1500fpm and ride it down, if you haven't caught up with the profile by 1000agl go around. It helps to start configuring as soon a you know they've kept you high.
