Note 1: A pressure type altimeter calibrated in accordance with the standard atmosphere:
- When set to a QNH altimeter setting, will indicate altitude;
- When set to a QFE altimeter setting, will indicate height above the QFE reference datum; and
- When set to a pressure of 1013.2 hPa (1013.2 mb), may be used to indicate flight levels.
Note 2: The terms "height" and "altitude," used in Note 1 above, indicate altimetric rather than geometric heights and altitudes.
