so this seems like an appropriate thread to ask this:
is the altimeter / pressure given for an airport a value that makes the altimeter read correct at the airport elevation?
or is it the the value so that 0 ft AMSL would read correct (yes this would be a bad idea still wanted to ask)
this would also mean the temperature error for an ILS decision altitude would be very low (that's why i was thinking about it)
edit: quick check of approach plates: the ILS i checked didn't even have a temperature limit.
