Yes, I believe at a Rank of 10k in JEE Advanced, besides having OBC advantage you might just make into the Aerospace Engineering Course at IIST Trivandrum. For an AIR of 10k, keeping the current trend of Moderate to Tough papers in consideration you would perhaps require to score at least 30-35% of the Total Paper (~120/360) and should plan and place your preparation and test taking strategy accordingly.
