India’s HAL flight tests second HTT-40 basic trainer aircraft prototype


Hindustan Aeronautics Limited (HAL) has reportedly conducted the first flight of the second prototype of Hindustan Turbo Trainer-40 (HTT-40).

Piloted by a HAL test pilot, the one-hour long flight was carried out at HAL in Bengaluru, India, on 20 May, The Press Trust of India (PTI) reported.

The maiden flight follows after the aircraft recently conducted high-speed taxi trials.

HAL CMD T Suvarna Raju was quoted by PTI as saying: “The second prototype was made ready within one year, and flew for one hour carrying out important manoeuvres.”

The HTT-40’s first prototype conducted its first flight in May last year.

The basic trainer aircraft is being indigenously developed by HAL to replace the Indian Air Force's ageing HAL HPT-32 Deepak trainers that are currently in service.

The aircraft will be primarily used for basic flight training, aerobatics, instrument flying and close-formation flights, whereas its secondary roles will include navigation and night-flying.

"With a maximum take-off weight of 2,800kg, the aircraft can be armed with gun, rockets and bombs to perform light combat and counter-insurgency missions."
