Company Name : HCL Technologies
Duration : July 2008 to Feb 2010
Position : Lead Engineer/Member Technical Staff.

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
