The headphone crackles in his ears as Wing Commander Pranjal Singh looks out from the cockpit of his Tejas Light Combat Aircraft, codenamed LSP-3, at the sun-baked runway stretching ahead. Once again he blesses the Indian designers who built the Tejas cockpit: in the Sukhoi-30MKI that he flew before test pilot school, he would have been dripping sweat.

“Trims neutral, brakes okay, all systems go from telemetry,” says Group Captain Toffeen’s calm voice.

Toffeen and his flight test engineers in the telemetry room of the National Flight Test Centre will monitor every system in Pranjal’s aircraft right through the flight, poring over radio data transmitted from LSP-3’s vitals. No patient in intensive care is watched so closely. Any serious glitch means aborting the mission.

“Confirm, monitored,” Pranjal acknowledges.

Toffeen clears him to go: “Take off with max AB, rotation at two-four-zero.” In test pilot jargon, that means take off at full throttle (maximum afterburner), rotating the joystick to get airborne at 240 kilometres per hour.

“LSP-3, ready for take-off,” says Pranjal to Air Traffic Control, which clears every aircraft.

The ATC is prompt: “LSP-3, cleared for take-off, wind 270, ten knots.”

Pranjal guns his engine to full power and the Tejas hurtles forward, the acceleration driving him backwards into his seat. In seconds he is at 200 kmph… 220… 240… and, as he pulls the stick, LSP-3 is sweetly airborne and climbing fast. This is the moment that every fighter pilot lives for.

But Pranjal is more than a combat fighter pilot, operating within tested and certified performance limits. As a test pilot for the Tejas LCA programme, his job is to push the performance envelope of India’s new fighter, checking how it reacts as he nudges it into uncharted territory.

“Each flight is a mission into the unknown,” explains Air Commodore Rohit Varma, Project Director, Flight Testing. Rohit, a tall, greying veteran who has spent a lifetime flying the unforgiving MiG-21 fighter, explains how each test flight deliberately takes the Tejas faster, slower or higher than it has ever been before, or on a mission like firing rockets or missiles, which could shut down the fighter’s engine by sucking up all available oxygen.

Business Standard is at the National Flight Test Centre (NFTC) in Bangalore to spend time with the pilots who test the Tejas, India’s first attempt to build a modern “fourth-generation” fighter aircraft. Since the first fledgling Tejas lurched into the sky in 2001, they have flown it to the limits of its flight envelope, but without rashly endangering the aircraft. While there are disasters in almost every fighter development programme, the Indian MoD’s zero-risk approach would make a Tejas crash a programme-threatening disaster.

Finely honed judgement is the first hallmark of a test pilot. Chatting with these men in the briefing room, I am struck by their maturity. This is no bunch of swaggering top guns, but experienced professionals in whom brash youth has given way to an impressive calm that must prevail in a life-threatening flight emergency.

Group Captain George Thomas, built like a bull, has commanded a squadron of Su-30MKIs. Group Captain Ritu Raj Tyagi, the most experienced of the group and a former Jaguar combat commander, ran the last Mumbai marathon as a diversion from flight testing. Captain Jaideep Maolankar, who cut his teeth flying Sea Harrier fighters off naval aircraft carriers, commanded warship INS Ganga as it chased pirates off the Somali coast. Group Captain Venugopal, like Varma, has commanded a MiG-21 squadron on the Pakistani border.

Even Pranjal, the baby of the team, is by conventional standards a veteran pilot, having commanded a Sukhoi-30MKI squadron. Now learning the ropes at the NTFC, he will extensively test the first two Tejas fighters that Hindustan Aeronautics Limited delivers to the IAF this year.

The LSP-3 streaks into the sky. Pranjal’s mission is to test a new smoke winder--an under-wing pod that trails smoke. The device will help the NFTC test the Tejas’ reaction when it flies into a jet wake, a deadly 250-kmph blast of air emitted by a jet engine flying ahead.

Jet streams confuse fly-by-wire fighters like the Tejas, which are kept stable by on-board computers. Swedish company Saab crashed one of their Gripen fighters during testing when it flew into one. But these NFTC pilots seem to believe that flying the Tejas into a jet stream is just another day at the office. This matter-of-fact approach to the unknown leads NASA to choose most of its astronauts from the test pilot community.

“Test flying only seems glamorous from the outside,” says Thomas, dismissing my suggestion that every young IAF fighter jockey must idolise him. “Our daily routine involves a great deal of what any fighter pilot would consider drudgery. There is plenty of daily paperwork, and loads of study across the aerospace domain.”

But the passion for flying keeps these aces motivated. “We have all finished commanding our fighter squadrons and would normally be moving on to flying a desk,” says Jaideep. “This allows us to stay in the cockpit longer, connected with the business end of combat aviation. We are a few metres away from a fighter plane at all times.”

Varma explains exactly what a test pilot does. “An operational pilot in a combat squadron does not have the luxury of criticising his aircraft. Whether he dislikes the cockpit layout, whether he finds the controls sluggish… he just does the job with whatever the nation provides him. But when he becomes a test pilot, all those years of frontline experience go into improving the aircraft for the frontline pilots.”

“The test pilot is classically the bridge between designer and field. That is his role. He needs to be able to talk the language of the pilots in the field, and translate their requirements into language that the designers can understand. He must bridge the disconnect between design and operations,” elaborates Thomas.

In western air forces, like the US Air Force, test pilots do nothing but flight testing. But while specialisation allows them to stay in close touch with test programmes, pilots become disconnected from combat flying. The IAF’s philosophy is different. “Our tactics are evolving so quickly that we feel it is better to keep moving pilots between test flying and operational squadrons. That brings the latest operational doctrines into aircraft development,” explains Thomas.

In the telemetry room, Toffeen controls Pranjal’s mission. The atmosphere is charged; hawk-eyed technicians are glued to their monitors to detect the first sign of trouble. Toffeen has done this for 21 years. “It is a really interesting job,” he laughs, relaxed and confident. “Every day is a new day.”

Pranjal’s voice booms over the speakers that broadcast all communication between pilot and flight engineer. The smoke winder has been successfully tested. Toffeen tells him to head back to base. There is no cheering or clapping; this is business as usual.

“Do you guys ever party, get drunk, let your hair down?” I ask Rohit.

“Not this week, definitely. We will be doing Tejas aerobatics twice daily and, as an article of faith, we don’t drink for 48 hours before flying.” But then the professional mask slips just a fraction and there is a gleam in the air commodore’s eyes. “But don’t go away with the impression that these guys are loners. Test pilot school parties are famous in the air force.”
 
Why India allows media to space canters, control rooms, key people etc. is pathetic.

My post is not specific to this thread news but to the larger scenario.

It was horrific to see media with their video camera recording inside Agni 5 test command and center they were filming computers data and reading everything, it should be avoided.:tdown:

This is the case in many countries. What do you think has been shown by these pics that compromises security? If anything I'd say India is too secretive on most projects and most military units.
 
Heheheh...........

True story

Russian cockpits are generally rather uncomfortable compared to their western counterparts. The same goes for visual freedom. In western aircrafts you have greater visibility. Tejas designers follow the western philosophy of aircraft construction.

You missed his point. He was most probably laughing at INDIAN DESIGNERS. In short trolling
