4.2 Set Altimeter
The Set Altimeter page (Figure 4.5) allows the user to adjusts the barometric altimeter. A barometric
altimeter calculates altitude based on atmospheric pressure . Since atmospheric pressure can vary sub-
stantially with meteorological conditions, and so with time, the barometric altitude also varies according.
In order to have the correct altitude for a certain place the altimeter should be calibrated.
Calibrating the altimeter can be achieved by entering the know altitude of the location. Entering an
altitude automatically calculates the QNH, which is the local barometric pressure adjusted to sea level.
Alternatively, the altimeter can be calibrated by adjusting the QNH for the local, and time. Changing the
QNH will adjust the barometric altitude.
