As Aerospace engineering involves design and manufacture of very high technology systems, the job requires manual, technical as well as mechanical aptitude. Though highly paid, work is very demanding. The specialisations include in areas like structural design, navigational guidance and control systems, instrumentation and communication or production methods or it can be in a particular product such as military aircrafts, passenger planes, helicopters, satellites, rockets etc. They find a very good demand in airlines, aircraft manufacturing units, air turbine production plants or design development programmes for the aviation industry. The main thrust in this area is on design and development of aircrafts to space and satellite research.
