  The Tejas Gun firing trials                                                                       Prof Prodyut Das.   The development of the Tejas has attracted a lot of followers from the Indian Aeronautical community. In the general disappointment with dates what has slipped under the radar is the fact that twenty one years after the first flight of the aircraft is not cleared to fire its gun. Jet engine/gun firing problem first came to attention in the 1950s . Today in terms of certification gun firing clearance should be   a “low hanging” fruit.

It will hold up certification....
