MS-21 'electronic bird' now simulates tough flights on the ground
Russia’s GosNIIAS built a new MS-21 test rig to stress onboard systems before first flight, including dense traffic and ACAS-X scenarios.

Specialists at GosNIIAS have assembled a new test complex for the MS-21, designed to push the aircraft’s onboard systems through demanding scenarios before the jet ever leaves the ground. The setup is a hardware-in-the-loop stand known as the “Electronic Bird”: instead of running avionics in an abstract model, it operates the aircraft’s electronics in an environment that closely approximates real flight.
The goal is straightforward: catch faults on the ground before they surface during flight testing, when fixes become far more expensive. According to the developers, the core of the new platform is a radio systems simulator that combines air-target trajectory modeling, surveillance messages, transponder signals, and digital data exchange in a single environment.
That lets engineers test dense air traffic, complex takeoffs and landings, tracking of multiple targets, and other constraints faced by a real aircraft rather than a clean paper model. The stand is also being used to develop future surveillance and navigation systems, including technologies aimed at ACAS-X requirements, the next generation of collision-avoidance warning systems.

For a passenger jet, that is a critical layer of safety. These systems need to work reliably in crowded conditions, with multiple aircraft, commands, and radio signals all competing at once.
Similar stands are already a standard part of global aviation programs. Airbus and Boeing use their own “iron bird” rigs to verify the integration of avionics, actuators, and software before an aircraft flies. For the MS-21, this matters even more given the program’s prolonged import substitution effort: many onboard systems are changing, which raises the cost of catching errors late.
The MS-21 is a narrow-body airliner in the Boeing 737 and Airbus A320 class, with capacity for roughly 163 to 211 passengers depending on the version. In that market, airlines judge more than fuel burn — they also scrutinize the maturity of onboard systems. For the MS-21 program, the “Electronic Bird” is not just a catchy name, but a practical tool that could reduce rework during testing and certification.
