Many organizations in India and abroad hire diploma holders in aerospace. These include government agencies and private firms in aviation manufacturing maintenance and space research. Examples are Indian Space Research Organization (ISRO) Defense Research and Development Organisation (DRDO) Hindustan Aeronautics Limited (HAL) National Aerospace Laboratories (NAL) manufacturing companies that make aircraft or spacecraft or their parts airlines maintenance repair and overhaul (MRO) organisations and civil aviation departments.
Other employers are private aerospace or aviation firms and aircraft-part manufacturing companies private airlines and MRO organisations or maintenance and support providers.
Diploma holders may work as aircraft maintenance technicians or aerospace technicians handling maintenance inspection servicing of aircraft or spacecraft systems.
They can also be design or manufacturing support engineers working on parts design airframe design integration quality control manufacturing or testing of aircraft/ spacecraft components.
Other possible roles include logistical support roles in production maintenance quality management composites manufacturing integration engineering or thermal design depending on employer needs.
Employers choose diploma holders because the course gives practical training in aircraft and spacecraft design manufacturing service and testing.
Diploma holders often have strong foundational knowledge in basics like aerodynamics aircraft systems avionics aircraft structures and are trained in lab and workshop work which suits maintenance manufacturing and support oriented roles.
Also as the aviation and aerospace sector is growing rapidly in India demand for technicians and support staff is rising making diploma holders valuable especially for maintenance repair overhaul manufacturing and quality control work.
Starting salary for diploma holders in aerospace engineering in India is usually around INR4 to INR5 lakhs per annum roughly INR25 000-INR45 000 per month for freshers.
With experience skills and expertise salary may increase as you grow in career especially if you join good organisations or take up specialised roles in maintenance design manufacturing or R&D.
If you keep learning and maybe later get a degree or certification employers may offer better roles with higher pay.
