Also - it wouldn't matter about bad weather if we did use ILS/Autoland everywhere.
Course_profile, consider the KISS principle,
if you please.
Then consider the implication to both flight safety and traffic flow if every time an ILS or G/S went U/S (or a bit flaky) a runway was shut down in VFR or weather other than " at minimums."
You'd be keeping more airplanes airborne longer in the volume of air around an airfield for
no good reason. So doing will decrease safety margins and increase the opportunity for error or mishap.
I don't think you've thought that idea through very well.
EDIT: Ancient Geek, thank you sir, well said.
EDIT 2: Course Profile, point on experience taken, and agreed based on my own experiences as well. Gravity and physics don't give a hoot how many hours you (or I) have.
