4. If on an ILS, then altimeter setting would not be of prime
importance. You ride the beam down until you see the R/W (or minimum
altitude and go around) and land. The beam (needles) is/are the
governing factor on az and el.

But if the altimeter is not set correctly you don't know where the DH
really is.


ILS is sited to have a touch down point
of say 2000 down R/W. Forget the exact figures.

1000.
