Avionics System Integration & Test

Test tools supporting faster, lower Cost, and low risk avionics system integration and verification test

Hardware-in-the-Loop Simulation and Test

Today’s avionics systems are based heavily on complex control systems which employ both high speed network technologies (such as Ethernet, Fibre Channel, and IEEE-1394) as well as legacy real-time data buses (such as MIL-STD-1553 and ARINC 429). To reduce development costs and to compress project schedules, system test programs often rely on Hardware-in-the-Loop (HIL) test strategies.

A HIL simulation and test strategy employs HIL test systems to simulate the sensors, actuators, and dynamics of the avionics system during the test and verification of embedded control systems. The test systems are computing systems which host software simulations of aircraft dynamics and which provide this data to the embedded system under test via avionics bus and network interfaces.


As experts in avionics communications technologies, AIT provides a wide range of avionics bus and network interfaces, supporting software, and engineering expertise to guarantee the success of any avionics system test program.

Fibre Channel with FC-AE-1553, HS1760, RDMA, and ASM

Fibre Channel can be found in many avionics system applications from weapons systems using FC-AE-1553 & HS1760, to display systems using FC-AV & ARINC 818, and even as the core network using ASM. Testing these systems and their components requires Fibre Channel interfaces with the support for the right upper layer protocol (ULP). No matter what the ULP we’ve go you covered.

With Fibre Channel test instruments supporting a multitude of upper layer protocols, supported by software tools and API’s, and backed up by our industry leading expertise with high speed networks, you can trust us to ensure all of your system test and integration needs are covered.

MIL-STD-1553 & ARINC 429 Bus Testing

MIL-STD-1553 and ARINC 429 remain among the most used technologies in military and commercial aircraft avionics systems today. These simple, easy to implement avionics bus solutions can be found on aircraft such as the F-16, F-18, B-1B, B737, B777, and A350 just to name a few. It’s hard to find an avionics system integration application that does not require either ARINC 429 or MIL-STD-1553 bus interfaces and tools.
