Polyrhythm Supports Flight Test Data Architecture

Polyrhythm Software is supporting flight test data architecture work for a commercial aircraft development program, helping define data flows, system boundaries, interface concepts, and high-level software requirements for a test environment where evidence quality matters from the beginning.

DAYTON, Ohio, July 1, 2025. Polyrhythm Software announced today that it is supporting flight test data architecture work for a commercial aircraft development program.

The work focuses on the software and systems decisions that shape how flight test data is captured, organized, reviewed, and used by engineering teams. Polyrhythm is helping define data flows, system boundaries, interface concepts, component considerations, and high-level software requirements for a commercial aircraft test environment where evidence quality matters from the beginning.

Flight test data is more than a record of what happened in the air. On complex commercial aircraft programs, it becomes part of the engineering control system. The architecture has to preserve context, make assumptions visible, support review, and give teams confidence that test results can drive the next decision.

That context includes time, configuration, sensor identity, data quality, processing steps, and the decisions tied to each test point. Telemetry standards such as IRIG 106 show how much structure sits underneath useful flight-test data exchange. Even when a commercial program does not use every defense telemetry convention, the same lesson applies: data has to be described well enough for engineers to trust it after the event is over.

“Flight test is where architecture meets reality,” said John Farrier, founder of Polyrhythm Software. “The goal is not more process. The goal is a data architecture the team can understand, trust, and change without losing control of the evidence.”

Polyrhythm’s support includes physical and logical architecture definition, data-flow analysis, system interface planning, component evaluation, collaboration practices, and software requirements development. The work reflects the company’s broader commercial aerospace capability in aircraft software, telemetry, test support, modeling and simulation, and systems integration.

“Commercial aircraft programs move faster when data paths and interface assumptions are made explicit early,” Farrier said. “The expensive problems show up when teams discover late that the data they need was not captured, not contextualized, or not connected to the decisions it was supposed to support.”

Polyrhythm’s role is focused on the early technical baseline. That means helping the program identify which data must be captured, where it crosses system boundaries, how it should be tagged, and how software requirements should describe the behavior of the test environment. It also means making sure the architecture can adapt as the aircraft, instrumentation, and analysis needs change.

The result should be a test environment that helps engineers move faster after each event. Good data architecture does not remove hard analysis. It makes the first questions easier to answer: what flew, what was configured, what changed, what data is missing, and which result supports the next decision.

Polyrhythm provides software and systems engineering for aircraft programs where integration, testability, and evidence discipline matter. The company helps teams build software, data paths, and technical artifacts that can survive real test environments and support decisions beyond the demo.
