Safran, HeliDax and AMS to introduce first complete Cassiopée-based digital flight data transmission system for helicopters

February 2020

Safran’s digital Cassiopée flight data acquisition, transmission and analysis system has received technical authorization for use on the EC120B helicopter.

Successful teamwork

In early January 2020, a year after signing the Letter of Intent (LOI), Safran, HeliDax and AMS (Aircraft Maintenance Systems) carried out the technical validation of the complete digital Cassiopée-based system on the EC120B helicopter.

A series of tests performed by HeliDax validated Cassiopée's ability to automatically transfer flight data between its different modules, including the Helicom V2+ acquisition unit, the Cassiopée Digital Flight Report app and the Cassiopée Helisafe web interface. The company also checked that this data was fully synchronized with the maintenance information system (MIS) of AMS.

"I'm very satisfied with our collaboration with Safran. The end-to-end data transfer functioned without a hitch, providing real time savings and fewer transcription errors. These are critical factors in ensuring maximum flight safety and reducing our costs." Joël Baudon, Technical Director of HeliDax

"The teams at HeliDax and Safran performed a tremendous amount of work in less than a year. This technical validation confirms our determination to continue developing this digital flight data system for helicopters. By calling on digitization and automation, we can continuously process data, handling larger amounts with greater accuracy, for an increasingly precise analysis." Florence Minisclou, Senior Vice President, Sales & Marketing, Safran Electronics & Defense Avionics Division

Step by step technical checks

  • Pre-flight checks
    The first step for HeliDax was checking the operation of the Cassiopée Digital Flight Report app. From user connection and recognition, to access to the fleet associated with its profile and the automatic generation of a pre-flight report, the app's pre-flight functions came through with flying colors.

  • Checks in flight
    In addition, the Helicom V2+ acquisition and transmission unit chalked up a large number of flight hours on the EC120B, confirming the aircraft's perfect real-time geolocation performance.

  • Post-lifght checks
    Flight data
    Following the flight, data recorded by the Helicom V2+ unit were automatically transmitted (via a secure wireless connection) to Cassiopée Helisafe and made available to the maintenance information system.
    Post-flight report
    At the same time, using the Cassiopée Digital Flight Report app and a Bluetooth connection, HeliDax's experts downloaded the data needed for the automatic pre-filling out of the post-flight report (position, flight time, engine operating time, number of landings) via the Helicom V2+ unit. The report was then completed and sent via the Cassiopée Helisafe interface to be made available for the MIS so that maintenance teams could import relevant data.
