What does AHRS stand for in aviation terminology?

In aviation terminology, AHRS stands for "Altitude and Heading Reference Systems." This is an important system used in modern aircraft for determining the aircraft's orientation, including its altitude and heading. AHRS provides critical information to pilots and navigational systems by integrating data from various sensors, such as gyroscopes and accelerometers, to provide accurate and reliable attitude references.

The system enhances situational awareness for pilots by delivering information about the aircraft's position in three-dimensional space, which is essential for effective navigation and safe flight operations. The systems typically replace traditional mechanical gyroscopes and are more accurate and reliable, contributing significantly to flight safety and performance.
