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.



Incorrect altimeter setting will not make you land short of the runway. It
will take you closer to the touchdown point. In addition, the altitude
shown at the final approach fix can be used to verify the altimeter
setting.
