Question:

 

When we go out to our aircraft, at our airport, and dial in the field elevation, what do the numbers in the Kolsman window mean?

 

 

and for all you "smarty-pants" what location & lat/long is your reference/standard?

It's the pressure that is assumed to be at mean sea level for that area based on the pressure reading that is taken at the aerodrome and then corrected for elevation above mean sea level.

 

I'm pretty sure I'm right. What am I saying, I'M ALWAYS RIGHT!!!! :P

 

Thats only true if the OAT is standard for that elevation, but otherwise correct...

So it should read - It's the pressure that is assumed to be at mean sea level for that area based on the pressure reading that is taken at the aerodrome and then corrected for elevation above mean sea level, and then corrected for non-standard temperature.

 

Is that correct? I forgot that pressure changes more rapidly with height with varying temperatures.
