The IAF will designate three evaluation teams, each of which will try out two aircraft from each competitor.

Finally, they'll move to Leh for high altitude trials involving a pair of aircraft from each competitor. Starting around September, evaluation teams from the IAF will visit the country of origin of each competing fighter for systems trials, which includes demonstration and testing of radar, EW suites, avionics, cockpit gear, countermeasures, weapons and weapon systems and communication integration.
