Sound altimeter setting procedures are an essential tool in ensuring safe separation from the ground and from other aircraft. 5.2 Principle of Atmospheric Pressure Measurement 5.2.1 Mercury Barometer (1) Principle of mercury barometer When a one-meter long, open ended glass tube is filled with mercury and is then turned upside down into a container Obtain an accurate pressure reading from the nearest weather or meteorological station. Set the current altimeter setting (above 31.00 "Hg.) Maintain this setting until out of the affected area or until reaching the beginning of the final approach segment on an instrument approach. Here you have an accurate barometer with an elegant analogical dial. The pressure readings for an area are mostly in the range of 29.70 and 30.20 inHg, with 29.92 inHg being the average pressure at the sea level. To calculate barometric pressure, look at a barometer and write down the pressure reading.

All aircraft: All aircraft will set 31.00 "Hg. Generally, low pressure systems are associated with cooler temperatures, precipitation, wind and storms. Set the indicator hand on your barometer. A pocket barometer. That air has a weight and presses against everything it touches as gravity pulls it to Earth. 411. Ambient Weather WS-2801A Advanced Wireless Color Forecast Station with Temperature, Humidity and Barometer The WS-2801A replaces the popular WS-2801. A barometer is an instrument used to measure atmospheric pressure. In general terms, provided that theelevation is less than about 1000 meters or 3000 feet,that would work fine for most purposes . OK, we know that air pressure decreases by 1 millibar forevery 8.2 meters we gain in height, so setting a barometershould be a simple matter if we know the elevation. in HG. Barometers and pressure altimeters (the most basic and common type of altimeter . A barometer is a scientific instrument that is used to measure air pressure in a certain environment. ; The Corrected DO Saturation Table gives data based on pressure increments of 5 mm (0.2") and tenths of a degree C. The WS-2801A adds a scroll mode which automatically displays each sensor every 5 seconds. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.. by Tim Brice and Todd Hall. Pressure can be adjusted up to ±10 inHg (338.6 hpa). When you return to the airport the next day the weather map is showing an area of low air pressure over the region, and the airport's barometer is reading 29.42 inches of mercury. 2 ™ 2. Hour (24) Reading Date & Time. However as atmospheric pressure drops as altitude increases it will be necessary to make an adjustment for your area before mounting your barometer.
