A fresher can expect 15k in a small company, 18k in an MNC, 21K maximum for an entry level job.

Once you have 2–3 years of experience you can expect 35 to 50 depending on the company.

Again after 5 years I have seen 65k is something every one would be looking for.

Please be advised that not all aerospace engineers get this salaries. It depends on how much is the person worth for a company.

hope it helps!!!
