Note that on the right hand side of the display is a scroll bar showing where the relative position of the

displayed menu compared to all of the other settings available in this menu.

All the menu options are explained on the folowing sections.

4.9.1 Set Altimeter

The Set Altimeter page (Figure

4.21

) allows the user to adjusts the barometric altimeter. A barometric

altimeter calculates altitude based on atmospheric pressure , and should not be confused with the GPS al-

titude, which is calculated based on satellite information (See the article in

http://www.xcmag.com/2011/

07/gps-versus-barometric-altitude-the-definitive-answer/

GPS versus Barometric Altitude). Since

atmospheric pressure can vary substantially with meteorological conditions, and so with time, the baro-

metric 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.

Altitude can also be set from the GPS. Below the QNH you will nd a Get from GPS eld which can be

set to Yes No or Auto. Adjusting this value to Yes will make the NAV SD take the altitude from the

GPS and adjust the altitude accordingly. The Yes is not stored in the setting, since it is a one time only

operation. The Get from GPS can also be set to Auto, with this value being stored in the settings. When

Auto is selected, after being turned On, the NAV SD will automatically set the altimeter to the GPS

altitude (once the a valid GPS signal exists), or whenever the pdop value is lower than the previous one.

Note that position dilution of precision (pdop) gives you an indication of how reliable the GPS altitude

is at the moment. The lower the pdop value the more accurate the position x.
