Given the latitude of the launch site is 13 degrees, why did GSLV fly to 21 degrees inclination for an equatorial mission?

Probably in order to not drop the SRBs and first stage over land if going due east.

What land is east of the launch site that can be avoided by flying to 21 degrees rather than 13 degrees?


Myanmar and Thailand. I have a feeling that the first stage would be travelling fast enough to potentially reenter over those countries. But the SRBs would be okay as they would be going slower upon separation.

It's about 1800 kilometers from the launch site to those countries. The second stage (the first stage is the SRBs) is going to overfly any land to the east of India, the question is why fly to 21 degrees, what is the benefit for creating a drop zone there?

That, I don’t know.
