Now Approved For Lear 31, 35, 36 Series

Rockwell Collins says its AHS-1000 Attitude Heading Reference System (AHRS) has received a Supplemental Type Certificate (STC) for installation on the Learjet 31/35/35A/36/36A aircraft. The announcement was made today at the Aircraft Electronics Association Convention in Dallas.

Rockwell Collins AHS-1000 was designed to replace previous-generation analog and iron gyro systems. It requires no air data sensor input, eliminates costly aircraft re-wiring and offers operators a cost-effective upgrade solution from traditional iron gyros and AHRS technology. In addition, the AHS-1000 is smaller and lighter, and offers increased performance and reduced maintenance costs.

By using digital quartz Micro-electro-mechanical Systems (MEMS) sensors in place of conventional spinning wheel gyros, the AHS-1000 delivers significantly greater reliability than traditional gyros and attitude and heading technology. It will also withstand extreme environments involving high roll rates and vibration.

The primary function of the system is to provide measurements of the aircraft pitch, roll and heading Euler angles for use by the flight deck displays, flight control system, flight management system and other avionics equipment. In addition, it provides high quality body rate and linear acceleration outputs for enhanced flight control system performance.
