In the plane, the pilot is advised of his altitude by means of an altimeter. The altimeter registers height by sensing the barometric pressure at the altitude at which the plane is flying. This is done by a pi tot (pronounced "pee tot") tube assemble mounted to the outside of the plane. The tube samples the air outside the plane and the altimeter basis it's reading on this information. However, the pilot must set his altimeter base line from information from the weather service prior to flight and be aware any changes during flight.
Another means of determining aircraft altitude is with RADAR. RADAR is sound waves sent out from a broadcast antennae and is bounced off an object in the air. by calculating the time it takes to get a "return" signal man or machine can tell height, distance, number, and size.
