Press Release: Orolia ELT-DT selected by Airbus for GADSS compliance


Press Release hub banner blue with title in red white and blueOrolia has been awarded a single source, multi-year program contract to supply its next-generation Emergency Locator Transmitter, Distress Tracking type (ELT-DT) for all Airbus aircraft programs.

The Ultima-DT is the latest solution from Orolia’s ELT line, based on its proven Kannad technology. It was developed in response to recent aviation safety mandates to enhance global aircraft tracking, following the MH370 and AF447 accidents. As per the ICAO Global Aeronautical Distress and Safety Systems (GADSS) recommendation and European Union mandate, all new aircraft delivered from January 2023 shall be able to autonomously report their location anywhere in the world and determine the end of flight location to help rescue teams rapidly locate the aircraft and recover flight recorders.

Unlike traditional automatic fixed ELTs which are stand-alone units, the Ultima-DT is tightly connected to the avionics system. It activates upon detection of a potential distress condition and starts transmitting automatically while the aircraft is still in flight. This next-generation ELT autonomously acquires the aircraft’s location and sends a 406 MHz message in real time, including the accurate location, to the Cospas-Sarsat distress alert organization.

Orolia CEO Jean-Yves Courtois said, “We are extremely proud to be selected by Airbus to provide with the world’s first aircraft manufacturer compliance with the latest safety regulations. A single-source, multi-year program selection for the delivery of mandatory equipment is a testimonial to our innovation capabilities, the reliability of Orolia as a critical equipment manufacturer, and our know-how in terms of large and complex program management.”


Orolia’s Ultima-DT will be installed on a standard basis on all Airbus commercial aircraft programs, including the A220, A320 family, A330 and A350. First units will be delivered to Airbus for final assembly line installation in 2022, ensuring that aircraft delivered from January 2023 meet the autonomous distress tracking requirements.

The Ultima-DT also allows operators to fully comply with the latest EASA/FAA safety requirements applying to non-rechargeable lithium battery powered equipment. As part of its efforts to support airlines in their regulatory compliance projects, Orolia is also offering its portable Ultima-S ELT which meets these special conditions.
