By the way, an ILS approach ends at DA, not MDA.


Isn't it "DH" now?


A precision approach has both a DA and a DH. DA is the Decision Altitude
(i.e. MSL), and DH is Decision Height (i.e. above the ground, although I'll
admit that I can't remember if it's above the threshold or above the
touchdown zone, or maybe something else).

For some reason, people tend to say things like "The DH is 680", when they
really mean "The DA is 680, and the DH is 200". It's sloppy, and wrong,
but somehow people tend to be able to figure out what they're talking about.
