Shadin Avionics has released two new products in its AIS-360 product family. The AIS-360 Inertial Adapter is a simple magnetic variation solution for ageing inertial systems, while the AIS-360 LoHi Converter addresses the common problem of mating old and new technology with IO transmission speed matching. As COTS products, both are available now and will be presented in detail at the AEA Convention in Dallas this June.

The Inertial Adapter, also called a Magnetic Variance Adapter or MagVar Adapter, applies a correction to the magnetic heading label in ARINC 429 data stream. The adapter can be configured to combine true heading with magnetic variation data referenced from an updatable table residing in the adapter or alternatively, combine data from another source such as an FMS that has an updated magnetic variation table.

“IRU (Inertial Reference Unit) replacement is costly and complex. The AIS-360 Inertial Adapter provides a long-term cost-effective alternative, and we are seeing an increasing demand for this product,” says Brian McMillan, Shadin Avionics' chief technology officer.

The LoHi Speed Converter is an ARINC 429 data buffer that receives a low-speed stream and transmits it at a high-speed rate while maintaining data integrity and the same update rate. This function is particularly beneficial for modernisation efforts because it enables the preservation of fully capable existing low speed LRUs. The AIS-360 has two inputs and two outputs.

These COTS products are configurable, certified up to DO-178 DAL A and qualified to DO-160. More extensive customisation or additional functions can be easily implemented on the AIS-360 based on customer requirements.

Based in Eden Prairie, Minnesota, Shadin Avionics maintains a rich history of designing, manufacturing, and providing support services for fuel flow systems, engine trend monitoring, altitude management systems, air data computers and other instrumentation for turbine, piston and rotor aircraft for the military, general and corporate aviation markets.
