Aversan performed a landing gear steering control unit (LGSCU) software upgrade verification and validation on both the boot software (BS) and operating software (OS) for the Sukhoi SuperJet 100. New software versions were released to fix software bugs. Aversan also performed formal development for the SSJ100, which included a unit test (UT), software integration test (SIT), and hardware-software integration test (HSIT) as part of post-certification.
The Sukhoi SuperJet 100 is a regional commercial passenger jet that entered into commercial operation in mid-2011. It is the first aircraft of its size equipped with a full fly-by-wire system in order to maximize efficiency and reduce costs.
