Aircraft altimeter as used in North America An altimeter is an active instrument used to measure the altitude of an object above a fixed level. The traditional altimeter found in most aircraft works in measuring the air pressure from a static port in the airplane . Air pressure decreases with an increase of altitude - about one millibar (0.03 inches of mercury) per...

...have proven that a methane bubble can indeed sink a ship by decreasing the density of the water. Methane gas can also crash planes. The less dense air causes planes to lose lift. Also, the altimeter of planes (the instrument that measures the altitude) functions on the density of air. Because methane is less dense, the altimeter assumes the plane is climbing. Planes at night or in the clouds...

...had rudimentary air-pressure, gyroscopic, or electrically driven needle gauges and gimbal instruments. In the dark or cloud, a pilot was guided only by the simple artificial horizon and barometric altimeter, a gauge to indicate the rate of climb or descent, a clock, a 'needle & ball' instrument to showo sideslip and yaw, and magnetic or radio compasses (sometimes both). Despite completing hours...

...feeds precise latitude, longitude, time, roll angle and barometric altitude to the DARMS and camera systems. A true airspeed computer feeds true airspeed data to the INS. A combined altitude radar altimeter provides precise height above ground information to the pilot for navigational purposes as well as a signal to DARMS for film annotation. It is accurate from 0 to 50,000 feet (15,000 m) above...

...the frequency of the returned signal and comparing that with the original, the difference can be easily measured. This technique can be used in radar systems, and is often found in aircraft radar altimeters . In these systems a "carrier" radar signal is frequency modulated in a predictable way, typically varying up and down with a sine wave or sawtooth pattern at audio frequencies. The signal...

...sea level increase of 2.8±0.4 mm/yr. This includes an apparent increase to 3.7±0.2 mm/yr during the period 1999 through 2004 [27] and Envisat ( March 1 2002 -) also have sea surface altimeter components but are of limited use for measuring global mean sea level due to less detailed coverage. TOPEX/Poseidon began their series of measurements in 1992 . The POSEIDON-1 altimeter...

...sides of the lander beneath the RTG windscreens, giving a total launch mass of 657 kg. Control was achieved through the use of an inertial reference unit, four gyros, an aerodecelerator, a radar altimeter, a terminal descent and landing radar , and the control thrusters. Viking lander model (NASA) Communications were accomplished through a 20-W S-band transmitter and two 20-W TWTAs ...
