An altimeter is an instrument that measures atmospheric pressure and translates it into an indication of elevation above sea level. A basic altimeter consists of a capsule that expands and contracts with changes in atmospheric pressure, bending a spring and moving an indicator pointer. A barometric Altimeter uses atmospheric pressure to measure flight level. It is a useful tool for aeroplane pilots and mountain climbers. At lower elevations, the air is denser and has a higher pressure. As a result, the air pressure drops as a person ascends to higher elevations. This pressure is measured in hectopascals (hPa) or millibars. The barometric altimeter uses a sealed metal capsule linked to a pointer by a mechanical system that converts the expansion or contraction of the aneroid capsule into the movement of a gear-driven pointer on a dial, which is calibrated in feet or meters. These gears are connected to the pointer through a Kollsman window, which is adjusted by a pressure setting control. The Altimeter readings heard in radio broadcasts are a standardized value for pressure at a particular location and time, reducing the effect of changes in atmospheric pressure. The Garmin 76S and 76CSX, and other GPS units with a built-in pressure sensor, display geometric height and barometric elevation on the satellites page and record this information in the track log. A radio altimeter measures the height of an aircraft above the ground based on the time it takes for a radio wave signal to travel from the aircraft to the ground and back. Its accuracy depends on the quality of the environment, especially a clutter-free environment. This can be achieved by using a patented depolarization panel, which makes it possible to measure the height of an airplane with a precision comparable to the measurement performed on board the aircraft. The Altimeter is a vital piece of equipment for aircraft and spacecraft pilots. It is also used by skydivers and mountaineers. Simple barometric altimeters work by determining current atmospheric pressure and comparing it to the air pressure at sea level. However, this model can run into problems in different weather conditions. In aircrafts, altimeters are a critical instrument that help pilots accurately determine their height above the surface below them. They are also known as barometric altimeters, and they use a stack of evacuated aneroid chambers that expand or contract depending on air pressure. The needles on the instrument then point to an altitude in feet or meters. Most aeroplanes use barometric sensitive altimeters. These are simple devices that measure changes in atmospheric pressure and have no reference to ground or sea level. When correctly set, however, these altimeters show the aircraft's height above mean sea level (MSL). Commercial airplanes are often fitted with radio altimeters that work by transmitting a radio signal to the ground. The reflected signal takes a certain amount of time to travel back to the aircraft, and the system then performs a calculation to determine the aircraft's altitude. These types of radio altimeters require separate transmitter and receive antennas to operate properly. A skydiver uses an Altimeter to help determine the correct time to deploy their parachute. These electronic devices operate by measuring changes in barometric pressure as they plummet through the air and convey the altitude to the jumper with a digital number on a screen or an analogue face. Audible altimeters also offer color indicators which allow skydivers to monitor their altitude in free fall by transitioning LED lights on the device. The Altimeter is an essential instrument for aircraft, as well as for skydivers and hikers. It uses a barometric pressure sensor to determine one’s elevation above sea level and can be used in conjunction with a map and compass for navigational purposes. However, it can be inaccurate if air temperatures change significantly or if the weather changes.
