- Or in another city
- Or at a nearby AFB or NAS or MCAS

1 - Not necessarily. I have flown a few ILSs that the GS starting acting erratic but yet no flag so I abandoned the approach. Once in IMC this happened and I came back around for a LOC only. Tower had an alarm in the tower cab after I said something.
HSA?? What’s that?
2- Yeah, we call that a visual approach.
3 - Assuming another approach is available and the equipment isn't co-located in the same facility.
4 - GCA? I assume you mean ASR or PAR. If you are approved for that.
5 - If its the back course is to the same runway you cant do it. Remember an ILS is also comprised of a LOC signal. No signal for either GS or LOC if the equipment is overheated. Some airports only have one shack for several runways. AFW uses the same freq & equipment for the ILS for opposing approaches.
6 - If you have the gas.
7 - Most airports don't have a military airfield nearby
8 - Not any more zany that your ideas.
I have also worked for an airline that could not use a certain airport for a couple of days because the ILS shack was struck by lighting.
