Re: Tejas Mk2 Medium Weight Fighter: News & Discussion - 23 February 2019

As early as 2017, work was happening on auto-landing based on navigational aids and AI based vision. They must have progressed a lot from there. Flying from point A to point B over a list of waypoints is routinely done by all airliners from 80s. Tejas can definitely do that. Approach and landing is ...
