The HTT-40 has completed spin tests to the left and right — a manoeuvre in which the aircraft is deliberately thrown into a dangerous uncontrolled spin and then recovered safely into level flight

In flight-testing on 7th September in Bangalore, HAL’s test pilots threw the HTT-40 into multiple spins and, each time, the trainer returned to level flight smoothly. In so doing, the HTT-40 cleared the so-called “Six-Turn Spin Test”, regarded as the ultimate and most difficult test for a trainer aircraft.

A few more tests are due to follow before the aircraft can get its operational certification, likely in end-2019, according to a person familiar with the program.
