You said that you know that "these master courses are not highly regarded in the aviation industry"". Who is telling you this nonsense? In another post you were told that the FAA dispatch licence was useless outside the USA; your sources of information are truly misguided; as will you be if you listen to them.
A masters degree in an aviation discipline from an accredited university such as Embry Riddel, Cranfield, London City, to name a few, is a marvellous tool to help anyone with the drive, determination and ambition to succeed in the aviation business, that is a fact!
If the awareness of that at Chennai airport (not exactly a centre of aviation academia) is somewhat un-illuminated then that is not at all surprising.
Maybe check out some of these 'not-so-highly regarded' universities and see for yourself who their professors, lecturers, guest speakers and acadamics are. You might be surprised by the 'highly regarded' individuals who feature there. But then again, don't take my word for it, ask your mates at the airport
