Pressure altitude is the altitude at which your aircraft performs on a non-standard day. Learn about its significance here.

See the National Weather Service explainer for more on the differences between station pressure, altimeter setting, and mean sea level pressure.

QFF is not typically used directly in an aircraft altimeter, and is a code that refers to what a meteorologist would typically call MSLP or Mean Sea Level Pressure, which can vary a bit from the ...

The potential for interference between 5G signals and the radio altimeters long used by pilots has divided the telecom and aviation industries.

Pressure Altitude Pressure altitude is the indicated altitude when an altimeter is set to 29.92 inHg (1013 hPa in other parts of the world).

You may not know that it can also function as a real barometer and altimeter, allowing you to predict changes in the weather by monitoring atmospheric pressure, no matter where you are.

Airhub took preventative measures after the Paris incident, underlining the importance of QNH pressure settings, and implementing flight-data analysis procedures to identify mis-set altimeter events.

The volcanic eruption in Tonga generated pressure waves in the atmosphere that quickly spread around the world.

French investigators are highlighting the importance of validating altimeter pressure settings, after a Hop Bombardier CRJ1000 descended below the glidepath on approach to Nantes.

I was recently looking at an altimeter for climbing fourteeners. My concern is that it works on barometric pressure, so changes in the weather could give me a false reading. First, was the ...
