"HIGH airport"
FIS-
>>If you are landing at a very high airport<<
If you mean a high "altitude" airport, then the corrections are the same. It makes no difference if the airport is sea level or 5000'. It's the indicated altitude ABOVE the airport that is in error in cold temperatures.
If you mean a high "temperature" airport, then no corrections are made. Your actual (true) altitude will be in error, but you will be higher than indicated. I know of no procedure to correct for this, nor have I ever heard of anyone doing so.
The correction procedure is spelled out very well in Jepp page CA19 or in the AIM (US).
