At a time of aerial skirmishes across the Loc, as claims and denials rend the air, it바카라s relevant to look at a hazardous eventuality that the professional combat pilot may face. An aviator like Aman Nautiyal, for instance. When seven failures hit Nautiyal in a single sortie, within a matter of two minutes and forty seconds, his brain did not get cluttered. 바카라It actually started working more efficiently,바카라 says the former Indian Air Force fighter pilot, 바카라ensuring that I took the required actions correctly.바카라 At that speed, those couple of minutes were long바카라Nautiyal says he absorbed so much of what was going on inside the cockpit that he could describe it for hours later.
But fire is a different proposition altogether. A quick glance at the rear-view and he saw that the entire aircraft was on fire, just a metre behind the cockpit. 바카라Eject! Eject! Eject! came as naturally to me as a fish takes to water, with an inherent desire to curl up in the pre-birth womb posture,바카라 Nautiyal tells Outlook, recalling an experience that took place more than a decade ago on a routine training sortie, but whose vivid, elemental details are imprinted deep within his mind. It바카라s what every fighter pilot is prepared for each time he climbs into his aircraft but it is, fortunately, something most of them don바카라t encounter in their entire flying career. 바카라The back must stay ram-rod straight during ejection so that the vertebrae don바카라t say hello to each other. Survival instinct, coupled with training, ensured that I took the correct posture.바카라 The aircraft was by now in a spin. With a smooth pull on the ejection handle between his legs the cartridge under the seat fired, propelling Nautiyal at high speed into the twilight of a breaking dawn 15,000 feet above ground.
The explosive-charged pilot ejection seat is nearly 80 years old. Yet, the intricate details of an escape from an aircraft spinning out of control are strikingly different. Cut to 2019, and some recent events바카라all unrelated. Last week, one image that stood out was that of a college student in Bangalore holding the hand of a Surya Kiran acrobatic team pilot lying on the ground, minutes after a mid-air collision, till medical help arrived. The pilot바카라s parachute had landed in a residential locality and a few residents were the first to reach him even as the crashed aircraft set off fires on the ground. In early February, a Mirage 2000 aircraft crashed during a test flight in Bangalore. Though both pilots had ejected, they died of injuries. A few weeks prior to that, a Jaguar pilot had ejected safely in Uttar Pradesh.
As professionals who plough the heavens at uncommonly high speeds will tell you, pulling the ejection handle is the last resort and no two ejections are alike. But what exactly happens when that handle is pulled? A series of automated sequences kick in, all taking place in milliseconds (see box).
바카라There could be a lot of situations where you have to get out of the crippled aircraft because you have no other option. That is how it is,바카라 says Air Chief Marshal (retd) Arup Raha, whose encounter with high g-force came early in his career, even before he was commissioned as an officer into the IAF. A cadet in training at the Air Force Academy in the early 1970s, Raha바카라s first sortie on an HJT-16 trainer aircraft turned out to be unforgettable바카라his instructor N.M. Gupte and he had to eject when the engine failed. When the canopy flew off, a wind-blast and the jolt from the seat flying off hurled the young pilot into a tunnel of nothingness바카라a blackout.
Pilots deal with gravitational force all the time when up in the air. Even under normal 3-4g, it could be difficult for people to move their hands and head, an IAF officer says. But the force acting on the body when the seat fires off ranges between 17-25g. 바카라That is, your body weight increases 17-25 times,바카라 explains Raha. So, blood and body fluids are rushing down to the feet, and vision tunnels and greys out momentarily. An ejection handle, therefore, is located between the legs (some models do have a second handle at the top of the seat too) so there바카라s minimal movement. Besides, ejection, unlike flying, cannot be simulated.
Retired Air Marshal V.K. 바카라Jimmy바카라 Bhatia recalls that when he was a cadet training at Hakimpet in the 1960s, there used to be a catapult-like device to closely replicate the process. 바카라The Vampire trainer had an ejection seat, so batches before us went through some sort of practice,바카라 he says. Much like the actual process, a cartridge charge launched a seat바카라fitted on vertical rails바카라up several metres; then the trainee was lowered down. The 바카라simulator바카라 device was apparently discontinued later. In his 40-year career as a fighter pilot, Bhatia says he was fortunate enough to pick the aircraft back each time he had a close call. Pilots go through various drills, cockpit checks and blindfold checks everyday. 바카라With eyes closed, one should be able to know where all the levers, the instruments and their control switches are,바카라 says Bhatia. The same daily drill goes for an ejection바카라feet together, hands-in, straight-back, pull! That is, practising for an eventuality that might never arise in one바카라s flying career, over thousands of hours of flying time바카라that바카라s how crucial getting yourself out of a malfunctioning aircraft is.

바카라To put it simply, the tail of the aircraft was travelling towards me at 250 metres per second and prudence demanded that I clear its height comfortably before it reached me,바카라 says Nautiyal, who retired a couple of years ago as air commodore. After clearing the aircraft tail, the seat stabilises with the help of drogue parachutes. 바카라So that I found myself sitting erect on a chair, mid-air at an altitude of 4 kilometres, the minus 16 degrees chill caressing the beads of stress-induced sweat on my brow. A few milliseconds later, the cutters emanated a ghastly metallic chopping sound and the seat separated outwards from my back and bottom,바카라 he says. As he tumbled downwards, a drogue parachute (a small chute that stabilises the pilot)opened, bringing him right side up in a few milliseconds with an immense jolt, so 바카라that all my joints released nitrogen almost simultaneously, sounding like a drummer바카라s crescendo바카라. Next, the main chute deployed. The next six-and-a-half minute descent was smooth till he splashed into the sea. Nautiyal was winched up by an IAF helicopter. In four months, he was back to flying.
A procedure so sudden, in environs so hostile, has to have a punishing toll on the body. Damage to the spine, mostly compression vertebral fractures, is the common form of injury in ejections, much of it relating to the posture while pulling the handle. 바카라The worry of the doctors normally is that sometimes this compression of the vertebrae shows up slightly later. So they make sure that you lie down straight and relax and not do anything that might stress and strain your backbone further,바카라 says Arup Raha. The toll on the human physique바카라and these are extremely fit men바카라is underlined by the fact that if a pilot has ejected twice, doctors normally don바카라t permit him to fly anymore in an ejection-seat aircraft. 바카라That바카라s because you have a lot of forces acting on your body which could result in injuries later on in your life,바카라 he says.
바카라When you eject, your body is already prepared for this event and you can retrieve the situation,바카라 says Raha바카라in his case, he had regained his senses as the seat reached its apogee and started tumbling down. But his instructor Gupte바카라s situation was more precarious because he had to straighten out the aircraft after the co-pilot ejected. 바카라He had very little time to maybe take the correct posture and I think it was a very fortunate that his chute deployed in time...just maybe about 50-100 feet above the ground, to my mind. So he had some injuries,바카라 the former air chief says. Raha vividly recalls his first meeting with Gupte several weeks later바카라after the latter recovered from his injuries바카라as the cadets congregated for the flying routine.
The instructor took him around to meet the maintenance staff바카라the armament specialists who serviced the ejection seats and checked their cartridges and the parachute-prepare section which packed the life-saving equipment. 바카라It didn바카라t strike me until then to thank them. I learnt a very important lesson that day. It바카라s not the individual, the team matters more.바카라
