- 3. HCL Technologies Limited is a global IT services company headquartered in Noida, India. It offers services including software consulting, enterprise transformation, remote infrastructure management, engineering and R&D services, and business process outsourcing. HCL provided the Air Management System (AMS) verification services to GE Aviation. Project Description: Air Management System (AMS) is a DO-178B level A system, used to provide the anti-icing functionality and provide controlled air flow to the cabin. AMS controller software running on dual redundant TMS320F2810 processors detects the ice formation on the wings & horizontal stabilizer and provides proportionate hot bleed air to eliminate the ice formation. AMS controller software algorithm controls the Pressure Shut off Valves (PRSOV), Anti-Ice Valves (AIV), Cross Bleed Valve (XBV) and Flow Control Shut off Valves (FAV) to provide modulated bleed air to the anti-icing system and air flow to cabin. AMS Controller software receives the altitude, computed Air speed, Wheel speed, Gas generator speed information from the FADEC through ARINC429 interface. Based on the input and value status, AMS controller software tunes the valves accordingly and provides the health of the system, pressure and temperature details to Crew Alerting System (CAS) and Central Maintenance Computer (CMC) through the ARINC 429 communication interface. My Role & Accomplishments: As a Lead Engineer for six months, Lead a team of four Engineers involving activities like mentoring the team, problem solving, tracking the team progress and reporting to the project manager. As a Member Technical staff, I have developed the Requirement Based Testing (RBT) plan as per the requirements. Provide suggestions for continuous improvements in test automation and quality of the artifacts. Developed RBT artifacts for system level and unit level verification. Review of RBT artifacts as per the requirements. Ensure the RBT artifacts produced by team are in compliance with companies standards Documenting the problems as Problem Reports (PR). Tracking the Problem Reports and ensure the Problems are fixed by the development team. Provide Guidelines to the team to perform manual testing. Documents like Software Verification Cases and Procedures and Software Verification Report are prepared as per DO-178B level A certification standard. Conducted Peer Reviews, Technical Reviews on RBT artifacts as per the quality standards. Conducted technical discussion meetings, weekly status meetings Discuss with the quality team in Root Cause Analysis meetings and propose Corrective and Preventive Actions (CAPA). Ensure that CAPA resolutions are followed by the team. Language : C, C++, XML and TMS320F2810 specific Assembly language. Platform : TMS320F2810 processor.
