The clearance came well outside the approach fix, but at an altitude
below the GS intercept altitude on the IAP. It's also below the GS
altitude at the marker. The problem with this clearance is there's no
way I can verify my altimeter as I cross the marker. Normally on
during an ILS approach, we're suppose to check the altitude on the GS
as we cross the marker, and make sure it agrees with the GS altitude
over the marker printed on the IAP. This is an important crosscheck of
the altimeter settings.
