[12] An inquest into the deaths of the four victims was opened on 20 March at … So why didn’t they do so until after they were already in the microburst? A hands-off takeoff is one way to solve the problem. Prior to encountering the shear, the simulations always included turbulence, but no turbulence was present before flight 1016 entered the microburst. The cold, dense air plunges down to earth, creating a powerful downdraft that then spreads out horizontally in all directions upon striking the ground. On the front lawn of the house, the center section comprising rows 9–14 caught fire and burned over very quickly, killing all but two of the occupants who had survived the initial impact. Ref: History: Somatogravic illusion was responsible for the crash of Gulf Air Flight 072 in Bahrain. ATC just cleared you to descend to 13,000 feet over the mountains of Colorado. Specifically, this illusion usually happens when there's limited exterior visibility and a pilot reacts to body senses over actual flight path and instrument readings. If You Go-Around On A Visual Approach Under IFR, Do You Need To Contact ATC Immediately? Somatogravic illusions occur during rapid acceleration and deceleration flight movements. But just when it seemed like everything was under control, Captain Greenlee began to suffer from a subtle form of disorientation. After concluding its investigation, the NTSB recommended that controllers be required to update pilots about thunderstorm conditions, including such features as lightning, wind shear, and rain; that controllers be required to inform pilots of the highest precipitation level near the airport as indicated on their radar; that airlines re-emphasize the importance of strict adherence to standard procedures; that NWS meteorologists like the one in Atlanta be given the tools or staff to adequately disseminate information about rapidly developing thunderstorms; that wind shear training be diversified to prevent rote memorization of particular scenarios; that USAir ensure its instructors were providing wind shear training correctly; that USAir improve training to help pilots detect microbursts based on indirect cues; that the wind shear warning activate even when the flaps are in transition; and that all infants be restrained in a seat on takeoff and landing.

But by the time the fires were out and the situation assessed, it was clear that many people had not survived the crash. Of the 57 people on board, 37 died in the crash and its fiery aftermath, while 20, including all five crewmembers, escaped with their lives. A crash due to a somatogravic illusion simply shouldn’t have happened. Quiz: Can You Identify These 7 Cloud Formations? The report on the Afriqiyah Airbus 330 crash has put it down to somatogravic illusion (probably both pilots). The investigators concluded: “Evidence suggests that the flight crew may have been subject to somatogravic illusion caused by the helicopter’s flight path and the lack of external visual cues. At around this time, the rain increased from light to heavy, a downpour that witnesses described as a “wall of water” and “some of the heaviest rain [they had] ever seen.” Two USAir flights, caught in the deluge while at the gate, elected to delay departure until the storm had passed. Wed Jan 25, 2012 8:24 am #1030516. Furthermore, the controller did not provide any information to the crew about the magnitude of the storm. There were no survivors. If you fly at night or in instrument conditions, it's especially important to know about the somatogravic illusion. Summer thunderstorms in the Southern United States are an almost daily occurrence, so its presence was not particularly notable. After entering the storm, Captain Greenlee decided to go around not because of wind shear, but because he had lost sight of the runway. In this video we are going to talk about the sensory illusions. ‘Disorientation’ likely cause of aircraft crash 8 Tips To Make A Textbook Traffic Pattern Every Time, What To Expect On Your Private Pilot Checkride: The Oral Exam, Your Guide To Flying Commercial Steep Turns, How To Pick The Best VFR Cross-Country Checkpoints. Basically the crash was due to the pilots being disoriented, a phenomenon known as “somatogravic illusion.” Here’s the explanation: During a go-around after an aborted landing, a plane tends to be lighter than normal since it’s at the end of its flight and has burned up most of its fuel. When a pilot misperceives attitude and acceleration it is known as the ‘somatogravic illusion’ and can cause spatial disorientation,” she noted. Head-down Three of the 10 persons on board were killed and 5 received serious injuries. First, investigators had to understand why flight 1016 flew into the microburst in the first place. Did you notice that the pilot was catapulted off the carrier with his hands off of the flight controls?
