You rely on your aircraft and its systems to successfully and safely get you and your passengers to their destination, every time. Your aircraft has served you faithfully. You know its history. You rely on it to get you around the weather and to the destination on time, every time. Do you worry about reliability of your aging equipment? Are you concerned how much longer repair parts are going to be available? Have you heard that the new equipment is smaller and lighter? A few dozen more pounds of payload would be nice. When looking at the bottom line, new equipment must not only work with your current configuration, but the upgrades you are planning for in the future.
Those older AHC-85 and gyros are out of production. Parts to repair these units are in very limited supply, and once they are gone there is no chance to repair the unit. Don't have an Aircraft On Ground (AOG) situation while looking for parts to repair your current AHC-85 or gyro.
Designed for non-ARINC 429-equipped aircraft, the Rockwell Collins AHS-1000S provides synchro and analog heading, attitude, rate and acceleration information to the flight deck and other on-board systems. The AHS-1000S replaces iron gyros that use a five-wire synchro flux detector interface. The systems easily accommodate both options without expensive and time-consuming aircraft rewiring. The AHS-1000S operates in Basic Mode and requires no air data inputs.
