AS8003 Altitude Encoders: How are readings from silicon pressure sensors converted to pressure altitudes?

Altitude encoders are relatively simple devices. They are designed to be as inexpensive and reliable as possible. They are so cheap that if it fails, buying a new one is cheaper than a repair (and you ...

Why does aircraft weight influence position (installation) error in pitot-static systems?

At a given speed, the lighter aircraft will have a lower Angle of Attack than the heavier one, so at an actual 200 knots (and level flight), the indicated airspeed will have more effects from the AoA (...

AS8003 Altitude Encoders: How are readings from silicon pressure sensors converted to pressure altitudes?

Have a look at the ICAO standard atmosphere (Doc 7488). It contains formulas and tables for conversion between altitude and pressure and vice versa, but only for the standard atmosphere (1013.25 hPa /...

How to identify the faulty GPS-INS in dual redundant installation?

If you want a decent solution that may still have availability or accuracy issues, there are two traditional ways of doing fault detection and exclusion: comparison between sensors, and comparing each ...
