The two main retailers are Sterling Book House in Mumbai and the English Book Store in Delhi.
There are currently six books available.
EBS sells locally produced versions.
Sterling Book House sells UK produced versions. These are more expensive, but they include an interactive CD ROM covering all 14 JAR ATPL subjects
There are probably other retailers who obtain the books from EBS or Sterling Book House, but I do not know who they are.
A new book covering Radio Navigation is about to go to print, so it should be available in India in a month or so.
