EASA certifies Thales’s primary reference ADU
AAAA, Nashville, 30 April 2009 – Thales announced today it has received ETSO C106
certification from the European Aviation Safety Agency (EASA) for its primary reference Air
Data Unit 3200 for helicopters.
A key component of any navigation system, Thales’s ADU 3200 is capable of generating
primary flight information such as altitude, airspeed and temperature by measuring static
pressure, total pressure and temperature. This flight safety system for helicopters offers an
exceptional reliability of 14,500 flight hours.
Packed with high-tech
The compact, lightweight ADU 3200 boasts many innovations. For example, it is the only
ADU on the market employing algorithmic processing to eliminate errors due to helicopter
blade rotation. Integrating high-precision sensors, the ADU 3200 delivers excellent
performance when measuring low speeds (up to 20Kts), a feature much appreciated by
helicopter operators.
World first
To optimise development time, Thales used object-oriented technologies and Agile software
development methodologies. “Employing these innovative methodologies in order to obtain
the highest DO178B level A certification for the ADU 3200 is a world first,” said Yves
Joannic, Thales’s Vice President for Helicopter Solutions.
Thales’s ADU 3200 has been selected as original equipment on the following helicopters:
Sikorsky S-76D; Eurocopter EC135, 145, 155, 225, 635 and 725; UH-72A Lakota; and
Agusta A109 LUH.
