How to Read a METAR – Our Full Guide to Aviation Weather Reports

Pilot Institute

The altimeter setting for the aerodrome is 29.93 As a good general rule, the smaller the difference between the outside air temperature (OAT), and the dew point, the more likely it is that a cloud will form, and the lower its base will be. 9) Altimeter Setting A3000 Last but not least, you will find the aerodrome pressure.

Density Altitude Formula: How to Calculate it Correctly

Northstar VFR

Indicated altitude is the altitude read directly off the altimeter. If you set the altimeter to the standard 29.92, you can read the pressure altitude off of the altimeter. Let’s take KBJC’s field elevation of 5,673 and say the altimeter setting was 30.10. Pressure altitude is corrected for non-standard temperature.
