IRIG 106 Chapter 10 — .ch10, .c10
Files from any compliant recorder. The TMATS header is displayed and checked, and every channel is listed with its name, type and rate, ready to be placed on a display.
Free download
Open any Chapter 10 file. Replay the whole flight.
D.T.MUX Viewer reads IRIG 106 Chapter 10 recordings from any compliant recorder, as well as ETEP .mux files. Video, the trajectory on a map or in 3D, cockpit instruments, avionics buses and analog channels play back on a single time base — for the engineer analysing a test point and for the crew debriefing the flight.

WHAT IT OPENS
Your recording, whoever built the recorder.
Chapter 10 is an open standard: a compliant file describes its own channels in its TMATS header and time-stamps every packet. That is all the Viewer needs — no conversion, no plug-in per manufacturer.
D.T.MUX — .mux
The native format of ETEP recorders, read directly with the same displays and tools. It also converts losslessly to Chapter 10.
Live network streams
Chapter 10 UDP streams from any compliant recorder or ground system — like ETEP's D.T.MUX streams — are displayed in real time exactly like a file, with the same layout in flight and after landing. A test centre running several manufacturers' equipment needs one tool for all of them.
TWO USES, ONE TOOL
The test engineer and the crew look at the same flight.
Engineers need measurements; crews need to see what happened. D.T.MUX Viewer serves both from the same recording, without exporting anything to another tool.
Flight-test analysis
Oscilloscope with cursors and more than twenty automatic measurements, 3D waterfall and order-based spectral analysis, PCM decommutation with sync monitoring, MIL-STD-1553, ARINC 429, CAN and Ethernet decoding, sample-accurate alignment across every channel displayed — and packet-level integrity views (checksum errors, sequence breaks, gaps, bit rate per channel) to validate a file before trusting it.
Post-flight debriefing
Cockpit or sensor video, the trajectory on an offline map or in 3D over the terrain, and the integrated ARINC 429 cockpit — PFD, classic dials, navigation map, 3D vision — play back together with the recorded parameters. Stop on an event, go back, show what the aircraft was doing and when — then keep the record in a PDF report.
POST-FLIGHT DEBRIEFING
Replay the flight with the people who flew it.
Everything the recorder captured, on one screen and one time base: what the camera saw, where the aircraft was, what the instruments read and what the systems were doing at that instant.
Test pilots and flight-test teams
Review a test point with the pilot shortly after landing: the video, the trajectory and the parameters of the manoeuvre side by side, before the data even reaches the analysts.
Pilot training
The instructor replays the flight with the trainee — approach, manoeuvre or procedure — from the cockpit camera and in 3D behind the aircraft, with the instruments and the track. The discussion rests on what happened, not on what each of them remembers.
Mission crews
After a mission, the crew goes back over the route, the sensor video and the sequence of events. The recording never leaves the debriefing station: the Viewer runs entirely offline.
Incident analysis
When something unexpected happens in flight, the recording shows when and how: the parameter that drifted, what the video shows at that moment, where the aircraft was and in what attitude, in 3D over the terrain. The segment can be extracted and attached to the report.
3D FLIGHT
Replay the trajectory in 3D, over the terrain.
As soon as a recording carries a position — NMEA GPS or ARINC 429 — any cell can replay the flight on a globe with terrain relief: the aircraft oriented by its recorded attitude, its trajectory and photographic imagery, in step with the playback bar and on the same time base as the video and the instruments.
Five cameras, generic models
Chase, orbit, free, pilot or top-down view; click the trajectory to jump to the nearest recorded point. Light aircraft, twin turboprop, jet, helicopter, drone or target — no brand, no livery — or your own glTF model.
Measured or computed, always said
Evidence rendering in steps, or smooth rendering interpolated between two valid measurements — never across a gap. A quantity that was not recorded can be computed, and is then flagged as such.
Offline by default
A built-in globe works with no connection at all. Open imagery (Sentinel-2, IGN, swisstopo) or Esri with your own key is downloaded only when you ask for it.
Exports and reports
Trajectory, position and attitude to Tacview (ACMI 2.2), Google Earth Pro (KMZ) or a spreadsheet (CSV), with their provenance. The 3D view goes into the test report.
The 3D view is a reconstruction from the recorded position and attitude, on present-day terrain and imagery: it places the flight, it does not show what the crew saw.

FREQUENTLY ASKED
Before you install it
How do I open an IRIG 106 Chapter 10 file?
Install D.T.MUX Viewer on a Windows 10 or 11 PC and open the .ch10 or .c10 file. The Viewer reads the TMATS header, lists the recorded channels and lets you place them on displays — oscilloscope, video, map, instruments, bus decoders. No conversion step is needed.
Which recorders' files can it read?
Any recorder that writes IRIG 106 Chapter 10 compliant files, whatever the manufacturer, plus the D.T.MUX (.mux) format of ETEP recorders. Chapter 10 is an open standard: the file describes itself, which is what makes it readable by any compliant software.
Can it check a Chapter 10 file at packet level?
Yes. Besides the TMATS header, displayed and checked, the integrity and bit-rate views show checksum errors, sequence breaks, gaps and the bit rate of each channel, packet by packet — a suspect file is diagnosed before it is analysed.
Does it work in a test centre with several manufacturers' equipment?
Yes. It opens Chapter 10 files from any compliant recorder and displays any compliant Chapter 10 UDP stream in real time, whatever the manufacturer, next to ETEP's D.T.MUX files and streams — with the same layouts for live monitoring and for replay.
Is D.T.MUX Viewer free?
Yes, for recordings made with ETEP equipment: every function, with no time limit. For Chapter 10 files from other manufacturers' recorders, contact us for the licensing terms.
Can it be used for post-flight debriefing?
Yes. Cockpit or sensor video, the GPS track on an offline map, virtual ARINC 429 instruments and the recorded parameters play back together on a single time base. Debriefing layouts can be saved and reused from one flight to the next, and a PDF report keeps the record.
Can it replay the flight in 3D?
Yes, since version 1.70. When the recording carries a position — NMEA GPS or ARINC 429 labels 310/311 — any cell can replay the flight on a 3D globe with terrain and imagery, the aircraft oriented by its recorded attitude, with chase, orbit, free, pilot and top-down cameras. It works in file replay (not in live reception), needs 3D acceleration and the Microsoft Edge WebView2 component, and remains a reconstruction on present-day terrain and imagery, not what the crew saw.
Does it need an internet connection?
No. D.T.MUX Viewer runs 100% offline: recordings never leave the machine that opens them, which suits confidential flight data. The maps and the 3D view work offline too, on a built-in globe; finer imagery and terrain are downloaded only if you tick "Online".
Which video formats does it replay?
H.264, MPEG-2 and JPEG2000, synchronized with the data recorded alongside them.
Can it display data live?
Yes. Chapter 10 UDP streams from any compliant source and ETEP D.T.MUX streams are displayed in real time, and on ETEP ground-station cards the Viewer also acquires, records on trigger and replays.
Can I export the data?
Segments can be extracted and exported to CSV from both .c10 and .mux files, GPS tracks to GPX or KML, the 3D trajectory with its attitude to Tacview (ACMI 2.2) or Google Earth Pro (KMZ), and reports to PDF or HTML. For bulk conversion of D.T.MUX recordings, D.T.MUX Converter exports to binary, float, ASCII, Excel and MATLAB-compatible formats.
