Lightweight Data Recorder (LDR)

Product overview

When an aircraft is smaller, lightweight takes on a whole new meaning because of payload and performance limitations. The LDR from L3Harris provides a lightweight package for crash-protected recording of audio, image and flight data for general aviation and helicopter operators.

Outside of regulatory-mandated installations that call for specific recording parameters, operators may opt to install any or all subset(s) of these functions on their particular aircraft. While some installations may make use of only the audio and image recording capability, others may want to exploit the full audio, image, data (ARINC 717 or ARINC 429) and GPS recording. The built-in webserver allows operators to retrieve recorded data with just a laptop and web browser.

  • Certified – ED-155 and FAA
  • Features a Crash-Survivable Memory Unit (CSMU) to protect valuable flight information
  • Contains provisions for an analog camera as a video source

Key Features

Retrieve data easily

A built-in webserver in the Lightweight Data Recorder makes it easy for data retrieval and configuration with just a laptop and web browser. No expensive software or complicated cabling is required for on-aircraft downloads.


Use it all or adapt elements for other purposes

The capabilities of the LDR can be customized to meet the needs of individual operators and aircraft, unless they are being utilized for regulatory mandates with specific parameters. While some installations may make use of only the audio and image recording capability, others may want to exploit the full audio, image, data (ARINC 717 or ARINC 429) and GPS recording.
