Minutes, not hours, between landing and debrief
The data has to come out fast and without tools: a removable SSD, a replay that opens straight away, no conversion step that only one person knows how to run.
Recording every flight, every day, without turning it into a test campaign
A mission recorder lives in the production aircraft. It has to be light, line-replaceable, last for years and hand back its data minutes after landing. Debriefing, maintenance and training all depend on that routine holding.

THE PROBLEM
The daily cycle is the specification
A test recorder is tended by engineers; a mission recorder is handled by whoever turns the aircraft round. Everything about it follows from that difference.
It has to fit the series, and stay there
Mass, volume and power are fixed by the aircraft; the unit must be a line-replaceable item, qualified once, and still supported when the fleet is fifteen years older than the recorder.
What the recording contains
Bus traffic, video and voice from an operational flight are not neutral. Removable media, access control and a genuine secure erase are part of the recorder, not options to add later.
THE ANSWER
What ETEP brings
Recorders sized for the aircraft and the routine, with the software that makes the routine short.
Three sizes for three fleets
The Nano as a lightweight multi-role recorder with removable SSD, the M for avionics buses plus video and voice up to 16 TB, the DVR when the mission is mostly video.
Replay without friction
D.T.MUX Viewer opens the flight as it is; D.T.MUX Converter exports to IRIG 106 Chapter 10 and third-party formats; D.T.MUX Recover rebuilds a recording cut short.
Control from the cockpit
The Remote Control and the Advanced Remote Control show status, start and stop recording, and mark events, so nothing depends on a laptop at the aircraft.
Built to stay in service
Qualified to DO-160G and MIL-STD-810, with obsolescence managed over the life of the fleet rather than the life of a component.

CASE STUDY
Two real cases
As a rule, we do not name our customers. The configurations are real; the identities are not.
A secure audio recorder that changed nothing on the aircraft
Sixty-four audio channels, an encrypted medium, full TEMPEST certification — and the hardest requirement of all: fit inside the envelope and the interfaces of the system being replaced.

Instrumenting a production trainer without freezing the configuration
A European airframer needed instrumentation that could ship with every aircraft and still differ from one customer to the next. The answer was not a bigger unit — it was one that could be assembled differently.

The articles that explain
Acquisition & recording
FDR, flight-test recorder, mission recorder: what actually differs
They all record flight data onto solid-state memory in an aircraft. Beyond that they have almost nothing in common — and the differences are not technical, they are about who is asking.
Acquisition & recordingOnboard memory: SSD, cartridges and erasing for real
The specification that matters is not how fast the memory can write, but how slowly it is allowed to write on its worst millisecond — and what happens to the data when the campaign is over.
Acquisition & recordingRecovering data after a power cut or a corrupted recording
A recording that was never closed is not a recording that is lost. What decides how much comes back is a design decision taken long before the flight — and a few rules about what you do in the first hour.
Standards & formatsIRIG 106 Chapter 10, explained
Why flight-test data ends up in a .c10 file, what the standard actually specifies, and what it deliberately leaves to the vendor — a practical guide for engineers who record, download and analyse airborne data.
FREQUENTLY ASKED
What we get asked first
How much recording time does a unit give?
It depends on the streams: bus traffic alone runs for days on the smallest SSD, HD video fills storage in hours. We size the medium to the mission profile, and the SSD is removable so a spare turns the aircraft round in a minute.
Which formats can be replayed?
Recordings open natively in D.T.MUX Viewer and export to IRIG 106 Chapter 10 with D.T.MUX Converter, so your existing analysis tools keep working. Video comes out as standard files.
How is the data protected between flights?
The medium is removable and the recorder offers a secure erase, so the aircraft can be left without data on board. Encrypted mission storage is available where the operator requires it.
