As the aircraft – arriving from Blagoveshchensk – descended, its crew set the altimeter pressure reference to the sea-level QNH figure of 751mmHg (1002hPa). The instrument approach chart for Tynda ...

Barometric altimeters are most common, and measure altitude above sea level using atmospheric pressure. Modern commercial ...

Investigators have determined that the crew of an Etihad Airways Boeing 787-10 did not set the correct destination pressure reference for the altimeter before the twinjet dipped far below the ...

Atmospheric pressure, particularly the altimeter setting, is critical for pilots to determine altitude, especially in mountainous areas, and is derived from highly accurate, redundant sensors.

Aircraft altimeters, while ingenious mechanical devices, are susceptible to various inherent errors, including mechanical malfunctions, installation issues, and lag (hysteresis). Environmental factors ...

While traditionally a project geared more toward the model rocket crowd, a lot of people are flying quadcopters these days, and knowing the altitude your RC aircraft reached is a nice thing to know.
