Aerometric System For General Aviation

This article deals with design and partial realization of experimental aerometric system for general aviation. The height is determined by the barometric principle. However, the primary measurement of the pressure is performed by differential pressure sensor which is added by a low-cost absolute pressure sensor. This system allows a measurement of height, vertical speed and temperature of the environment. The accuracy of the system fulfills demands of civil aviation standards at low-cost. The article describes principle and advantages of height measurement by a differential pressure sensor, a design of an aerometric system and its components, and achieved measurement results. The article also outlines a possible future utilization of the system in the sector of ultralight planes and modern gliders.
