I know that air temperature impacts air density and therefore altimeter readings. However, I am curious if temperature is taken into account when an altimeter setting is provided by the FAA/airport.
Is an altimeter setting provided based upon the current observed conditions/temp or is it adjusted to the standard atmospheric temperature of 20C?
I have noticed higher readings when the weather gets cold and also see the warnings in IFR training materials about how cold temps show higher than actual readings. This made me assume that altimeter settings were provided based upon standard temps and not actual.
Thanks,
Larry
