Universal Avionics Attitude Heading Reference System (AHRS), AHS-525 is designed to meet the advanced accuracies required for the next generation flight deck, and seamlessly replaces existing analog directional and vertical gyros. It integrates with flight deck displays, flight control systems, flight management systems, weather radar, terrain awareness and warning system, flight data recorder and a host of additional avionics systems. When interfaced with Universal Avionics? EFI-890R, data display and control is managed directly through the EFIS, without the need for additional heading control panels that clutter the flight deck.

The AHS-525 provides stable and accurate aircraft analog and digital pitch, roll and heading measurements. The unit is designed with Microelectromechanical Systems (MEMS)- based technology, a system that combines the computational ability of microelectronics with the acuity and control of microsensors and microaccelerometers. This solid-state construction, with no internal movable parts, increases unit reliability.

AHRS Attitude Heading Reference System System installation components include the Attitude Heading Reference Unit (AHRU), configuration module to store configuration data and alignment offset values, external remote magnetometer for magnetic heading data, and a precision mounting plate that is permanently affixed to the aircraft. The fixed mounting plate allows the unit to be removed for service and replaced without repeated and timeconsuming realignment of the system. The unit?s compact size lends flexibility to installation, with possible mounting locations in pressurized, non-pressurized, controlled and non-controlled temperature environments.

The AHS-525 features digital, analog, discrete and synchro inputs and outputs (I/O) to support a wide variety of interfaces on Part 23, Part 25, Part 27 and Part 29 aircraft.
