Integrated Flight Data Recorder System for ED-155 crash protection standard Requirement. Data audio and image or video in a single lightweight recorder.
For turbine aircraft, weighing less than 5700 kg


The International Civil Aviation Organization, Annex 6 part I published in 2010 (transport commercial international aeroplanes) All turbine-engined aeroplanes of a maximum certificated take-off mass of 5 700 kg or less for which a type certificate is first issued on or after 1 January 2016 shall be equipped with ED-155 type Flight data recorder.

Low cost, integrated Flight Data Recorder (FDR) System for ED-155 standard Requirement. Data audio (CVR) and airborne image recorder (AIR) in a single lightweight recorder, with quick access to data via ethernet port on the front.

New-Generation Miniature Flight Data Recorder System for ED-155 Needs.

Recorder system, is integrated in a single box comprised of an Integrated Data Acquisition Unit, an Integrated Crash Survival Memory Unit (CSM), an internal or external Cockpit Area Microphone (CAM), Image Recording System Interfaces, a Data Link Recording System Interface and a Ethernet Maintenance connection.

When you don't have data bus or you don't have all parameters with it, this Sentinel unit proposes in option an autonomous AHRS system (attitude heading reference system), who is consists of sensors on three axes that provide heading, attitude and yaw information for aircraft and this system can be coupled to the GPS data.

A removable storage can be Also implemented to facilitate the Flight Data Analysis

J Typical Applications

  • Investigation of an occurrence (accident or incident).
  • Can be used for flight training.
  • Can be used for flight data monitoring.
  • Reduced insurance premiums, etc...
