Cockpit Voice Recorders (CVR) and Flight Data Recorders (FDR)

Flight recorders give the ability to monitor situations on an aircraft and understand what is happening in flight. The Cockpit Voice Recorder (CVR) is a type of flight recorder and another is the Flight Data Recorder FDR).

Cockpit Voice Recorders record the audio environment on board via the microphones of the pilots' headsets and can be used to investigate accidents or other incidents that have occurred on board. 

Flight Data Recorders are used to capture certain aircraft performance parameters measured by aircraft sensors. This information is transmitted to an accident-proof medium. 

Express readout overview

Key features

Fast turnaround

Using a patented auto-validation technique, Express Readout is the most rapid solution for providing readout and intelligibility reports, which are available in up to 3 business days from the readout request time. Reports can then be downloaded in various formats, including .csv files for further analysis. Additionally, users can re-test data within 30 days at no additional charge, to confirm the repair of faulty signals only.


Easy to use

The interface is easy to navigate and use, so training is minimal. Individual logins provide users with a customized dashboard and access to specific data.


Access to multiple flights simultaneously

Express Readout’s patented algorithms also identify unusual parameter patterns and highlight these to the user for inspection. Interactive charts allow users to inspect the parameters in detail and assess up to 50 flight hours of data, across multiple flights, within the same readout. The results are stored indefinitely on the secure platform, exceeding FAA and EASA regulatory requirements.


Automated self-service solution or full-service validation

Express Readout is available as an automated self-service solution or as a full-service validation, which includes an expert assessment of the recorded data. Our web-based, semi-automatic tool applies patented algorithms to identify suspect parameter patterns and highlight them so that the user can inspect them afterwards, with results stored indefinitely.


24/7 interactive platform

The secure, web-based platform supports all browser types, is simple to use, reliable, modern and customizable with full support.


Regulatory compliance

The platform is compliant with ICAO, EASA, and FAA regulatory framework for FDR readouts and with the EASA framework requirements on raw data retention policy for intelligibility readouts. It supports all recorders used on air transport, regional and business aviation aircraft, as well as helicopter platforms.

Data link Recorder Verification Services

L3Harris offer a streamlined process for providing operators data link embedded message decoding. Unlike Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR) verification; data link verification requires the operator to deliver data link decoded message readouts which are generated based on their defined operating parameters. This enables operators to follow the EASA framework to validate the devices are capturing the reordering properly. The L3Harris CVR intelligibility readout report follows “Guidance on CVR recording Inspection” produced by the Flight Recorder Partnership Group (EFRPG) and was published by the Bureau d’Enquêtes et d’Analyses (BEA) in 2018.

The L3Harris web-based portal allows the operator to upload the data and exchange the necessary decoded data quickly and electronically. All data is secure and proprietary to the airline so that only the operator can read the data link decode messages which were previously aligned to their defined parameters provided to the flight data analysis team when the account was activated. As part of the Express Readout service, L3Harris includes Level 2 intelligibility analysis for all CVR readouts.
