| Definition | An aviation quality digital barometer providing accurate and reliable pressure measurement over the range of 800 to 1050 mb. It had a unique construction consisting of three independently operating sensors controlled by a microprocessor. Triple redundancy ensured excellent long-term stability and measurement accuracy. Short term accuracy was determined by WMO as about 0.2 hPa and long-term accuracy (over approximately a year) was determined as approximately 0.35 hPa or 0.45 hPa if subjected to temperature variations in excess of 20 degC. | ||
