Altitude Measurement (Figure 3-5)
This mode measures the vertical distance between a level and
a specific pressure datum. Measurements of altitude are
calculated from local pressure according to ICAO standard
atmosphere tables defined in BS 2G 199: 1984. The default
pressure datum is the ISA, 1013.25 mbar. A user defined
pressure datum can be entered by the SET_ALT menu. This
datum can be a specified pressure datum known or required
by the user such as true sea level pressure or airfield ground
pressure at the time of measurement.
