It yaws, it spins, with Sukhoi you always win

It’s awesome,’’ gushes the man about his mighty machine. Other pilots would give anything to get strapped into the cockpit of the Sukhoi-30 MKI fighter, and Wing Commander Nirmal Singh Jamwar, the pilot flying them at Aero India 2003, worships the complex machine.

‘‘I have flown the Su-30 earlier. The MKI version is entirely different. This craft has thrust-vectoring, is more complicated and has more tasks to perform,’’ the ace pilot says.

Thrust-vectoring gives the aircraft its ability to manoeuvre. While Jamwar gives the 39-tonne machine — even the AN-32 weighs just 27 tonnes — full points, the fighter’s multi-role capability gives it the edge in every type of engagement.

Over Yelahanka, Jamwar does a complex manoeuvre, climbing up to 1.3 km after a roll-out. A small semi-loop later, he takes a 180 degree yaw turn. He rolls the machine on its back, does tight box turns and takes a turn at 650 km per hour exerting hard G-forces on himself and the co-pilot.

The fighter is capable of flying much slower than the 180-200 kmph that it flies here. As for manoeuvrability, the 180 degree yaw turn is the ultimate — it turns like a helicopter and does not bank like a conventional aircraft at any speed.
