The United States Air Force was faced with an integration issue on the C-130. They had COTS transponders that would only communicate via ARINC 429. Shadin responded to this need by producing a MIL-STD-1553 to ARINC 429 converter based off the AIS-460 platform which also interfaced to an altitude alerter to get preselected altitude to the transponder. This was successfully performed and integrated on hundreds of C-130s, ultimately saving millions of dollars in larger avionics upgrades. The United States Air Force required a digital output from the fuel quantity system. Utilizing the AIS platform, Shadin was able to perform the fuel quantity indication function while also providing the digital output that was requested. Shadin was able to do this at a fraction of the cost of other bidders as we were able to use COTS products to meet the requirements.
The UH-60 Black Hawk Helicopter is the U.S. Army’s primary medium lift utility transport and air assault aircraft. The UH-60A entered service in 1978 and has been used to this day. Through the years it has gone through several upgrades with the UH-60L in 1989, and the UH-60M and now UH-60V. While the U.S. Army is still operating the UH-60A, they are planning on divesting all Alpha model aircraft by 2024. As the Alpha models are acquired by companies and modified for multiple mission purposes such as firefighting, police, and other special mission rolls, they will require upgrades to keep them current. Shadin has found several instances where our product line has met this challenge. Such applications where this has been necessary, would be:
1. Converting legacy heading synchro into an ARINC 429 (Label 320) for newer avionics interface.
2. Converts attitude reference data (Heading, Pitch and Roll) from ARINC 429 into ARINC 407 synchro, this was done utilizing the AIS-450 platform for an autopilot interface, which prevented the costly replacement of an autopilot.
3. As newer avionics features are added to the UH-60 it is possible to integrate features like fuel flow, fuel remaining, and range information from devices like the AIS-380. Shadin has a long history of providing fuel flow data to Customs and Border Patrol UH-60 helicopters.
4. Now that Automatic Dependent Surveillance-Broadcast or ADS-B is a requirement for aircraft operating in specific airspace, there has been a need to provide air data information to upgraded transponders as the original air data systems were not sufficient or present to meet the demand. Shadin is now installing the FADC 2000 Air Data computer to meet that need.
The Beechcraft T-6 Texan II is a single-engine turboprop aircraft used primarily by the United States Air Force and many other countries around the world. With over 850 aircraft currently in service, it is one of the most widely used trainers in the world today.
As part of a solution patented by Advent Aerospace, the eABS™ was born. The system consists of left and right Brake Control Modules, left and right Wheel-Speed Transducers, a Digital Electronic Control Unit and a combined Control Switch and Annunciator in each cockpit. The Digital Electronic Control Unit was developed from the AIS-380 platform.
The eABS™ system is now certified under an STC on several platforms which include the Eclipse Aerospace (now One Aviation) 500/550 series Jet, Beechcraft King Air B200 / B300, Pilatus PC-12 and the newly upgraded Northrop Grumman T-38C with more to follow.
This is another prime example of how the AIS Platform was able to meet the needs of our customers. As this application uses the similar hardware throughout each application, ensuring optimal manufacturability, ultimately keeping the price very competitive in the marketplace.
Military Trainer (PC-7) was installing a new EFIS and wanted to retain the autopilot that was currently installed. The customer needed to bridge the difference between a typical EFIS-installation of an autopilot with that of a military EFIS; which included analog datums and ILS data. Shadin developed the Digital Autopilot Adapter (DAA) to enable the EFIS upgrade to occur, solving the connection issue. The solution received ARINC 429 data related to heading, course, localizer, glideslope, baro correction. It also provided the necessary analog data for the autopilot to function correctly.
The Fairchild Republic A-10 Thunderbolt II is a single-seat, twin turbofan engine, straight wing jet aircraft from Fairchild-Republic. Designed for the United States Air Force (USAF), it is commonly referred to by the nicknames “Warthog” or “Hog.” A-10’s official name comes from the Republic P-47 Thunderbolt, a World War II fighter-bomber effective at attacking ground targets.
The United States Air Force recognized the need to replace the existing Fuel Quantity Intermediate Device in the A-10 with a new design. The goal was to monitor electrical signals from the individual fuel tank probes, combine them and report fuel quantity while enabling superior reliability and reduce maintenance costs associated with supporting the legacy system. The solution was the Shadin Avionics A-10 Fuel Quantity Intermediate Device (FQID): an all-digital interface, MIL-STD-1553 data bus, featuring interchangeability with the existing component to support the fleet today and future cockpit upgrades.
