Altimeter Cold Temperature Correction Policy

correction

Greetings,

Below is the FAA, point of view about the subject


The possible result of the above example should be obvious, particularly if operating at the minimum altitude or when conducting an instrument approach. When operating in extreme cold temperatures, pilots may wish to compensate for the reduction in terrain clearance by adding a cold temperature correction.

Since the airspace is handling so many aircraft with technology differences, ranging for classic, to FMS advance types, it is very difficult for the time being to impose a technological solution of the problem, so today I think that the idea is that if all aircraft have the same altimeter error, than there is no error within the terminal area.
