Thales will provide its integrated electronic stand-by instrument (IESI) to modernize the Esquilo/Fennec helicopter fleet of the Brazilian Army. A total of 36 helicopters will be retrofitted with the Thales system, with completion expected in 2018.

The first batch are planned to be completed by 2014, when Thales’ IESI will be integrated into six initial helicopters by Helibras, the Brazilian subsidiary of Airbus Helicopter.

The IESI performs three back-up functions: artificial horizon, altimeter and airspeed indicator, all in a single line replaceable unit (LRU). Already flying on the Sikorsky S-76D, the Thales IESI has also been selected by Airbus Helicopters for its range of light and medium-lift helicopters including the Ecureuil family, the EC135, EC145, EC155, EC175 and their military versions, including the modernized AS 365 K2 Super Pantera.

Thales’ IESI has resistance to high intensity radio frequencies (HIRF), durability in humid, saline and high- vibration environments, and is able to receive and control other functions such as automatic flight control system (AFCS) back up and radio management system (RMS) back up.
