The Indian Air Force Test Pilot School is a unit of the Indian Air Force (IAF) that evaluates aircraft and systems for induction into user organisations. Most new aircraft types and major airborne systems must have ASTE's stamp of approval to be considered fit for service in India. While many countries have testing facilities of one kind or the other, training of flight test personnel is not often imparted in them. ASTE's Air Force Test Pilots School (AFTPS) is only the fifth such institution in the world.
