Explained: What black box holds inside and what can it reveal about Air India plane crash?
The flight data recorder from the crashed Air India flight was recovered on Friday, which is expected to provide a critical understanding of the cause of the plane crash that claimed the lives of 241 passengers and several people on the ground. The London-bound Boeing 787 crashed into a medical college hostel in a residential area of Gujarat's Ahmedabad shortly after takeoff on Thursday, June 12. The plane's digital flight data recorder or black box was recovered from a rooftop near the crash site, and the Aircraft Accident Investigation Bureau said that it had begun its work with 'full force.' Meanwhile, Civil Aviation Minister Ram Mohan Naidu said in a post on X that the black box recovery marks an 'important step forward in the investigation'. The Flight Data Recorder (Black Box) has been recovered within 28 hours from the accident site in Ahmedabad by AAIB. This marks an important step forward in the investigation. This will significantly aid the enquiry into the incident, Naidu added. A black box in aviation refers to two critical flight recording devices on an aircraft: Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR). Flight Data Recorder – This device records important flight parameters like speed, altitude, engine performance, heading, and flight control movements. Cockpit Voice Recorder – This records audio from the cockpit, including conversations between pilots, alarms, and ambient sounds. In the investigation of the Ahmedabad crash, the black box will play a key role in identifying whether the disaster resulted from a mechanical malfunction, engine failure, bird strike, onboard fire, or human error. The black box will offer comprehensive information about the crew's MAYDAY transmission, any system-generated alerts, and their efforts to regain control in the critical seconds following takeoff. Furthermore, the device will reveal information about the engine and control settings, in addition to what the voice recorder will show about the cockpit conversations, Paul Fromme, a mechanical engineer with the UK-based Institution of Mechanical Engineers said in a statement, as reported by the Associated Press. The DGCA said its enhanced inspection will include checks of various systems and a review of take-off parameters of the Boeing 787 Dreamliner aircraft of Air India owned by the Tata Group. Both FDR and CVR devices always collect and save data during a flight. The FDR logs technical and performance metrics, while the CVR records sound inside the cockpit, according to reports. In the event of an accident, this stored data is retrieved and analysed to understand what was happening mechanically and among the crew in the moments leading up to the crash. Aviation safety consultant Jeff Guzzetti, a former crash investigator for both the US National Transportation Safety Board and Federal Aviation Administration, said investigators should be able to answer some important questions about what caused the crash as soon as next week as long as the flight data recorder is in good shape. Investigators likely are looking at whether wing flaps were set correctly, whether the engine lost power, whether alarms were going off inside the cockpit and whether the plane's crew correctly inputted information about the hot temperature outside and the weight of the fuel and passengers, Guzzetti said, as reported by AP. Mistakes in the data could result in the wing flaps being set incorrectly, he said. (With inputs from agencies)

Ahmedabad Air India tragedy: Gujarat ATS recover Digital Video Recorder (DVR) from crash site; here's how it is different from black box
NEW DELHI: Gujarat Anti-Terrorism Squad (ATS) officers on Friday recovered a Digital Video Recorder (DVR) from the debris of the Air India Dreamliner that crashed shortly after take-off from Ahmedabad airport, killing dozens. Confirming the recovery, an ATS personnel at the crash site said, 'It's a DVR, which we have recovered from the debris. The FSL (Forensic Science Laboratory) team will come here soon.' Is DVR and Black Box same? DVR is not the same as a black box, which typically comprises two key aviation components: the Flight Data Recorder (FDR) and the Cockpit Voice Recorder (CVR). While a DVR is commonly used in homes, offices, or public surveillance systems to store CCTV footage, a black box is a highly durable, crash-survivable device that records flight parameters and cockpit audio — vital for understanding the cause of an air crash. The DVR could help track passenger boarding or the last visual recordings before the flight took off. The black box, meanwhile, remains the most critical piece of equipment in aviation crash probes. It records data like altitude, engine performance, and pilot conversation. As investigators continue combing through wreckage strewn across residential areas and parts of BJ Medical College's campus, the DVR could offer answers but the real questions are still locked inside the missing black box.

Whats A Black Box? How It Holds Clues To Air India AI171 Disaster
While rescue officials sift through the debris of Air India Flight AI171, which crashed into a physicians' hostel just outside Sardar Vallabhbhai Patel International Airport within minutes of taking off, investigators are relying on the plane's black box to reveal the reason behind the tragedy that claimed 241 lives. The Boeing 787-8, which was headed to London, dived from 625 feet, bursting into flames and filling the air with thick smoke. What Is A Black Box? The black box, ironically enough, is an orange-colored object consisting of two parts: the Cockpit Voice Recorder (CVR) and the Flight Data Recorder (FDR). The CVR records radio communications, captain and crew member conversations, and noises such as engine sounds or stall alarms, allowing experts to study important audio signals. The FDR tracks a minimum of 88 variables, such as altitude, airspeed, and direction of travel, with contemporary aircraft monitoring as many as 1,000 features, like flap lever positions or smoke detector activation, reports the National Transportation Safety Board (NTSB). Origins And Design Initially developed in 1953 by Australian scientist David Warren, whose inspiration was his father's death in a 1934 plane crash and the 1953 Comet crash, the black box has become an essential instrument for aviation safety. Painted orange for visibility, they are constructed from titanium or stainless steel to survive high-impact crashes, fires, and 14,000-foot deep-sea pressure. The FDR is usually installed in the aircraft tail, and the CVR in the cockpit. On helicopters, a single combined recorder monitors 800–1,200 parameters, according to Airbus. How It Survives And Functions Designed to endure extreme conditions, black boxes can transmit signals from ocean depths and are treated to remove corrosive salt if submerged. Data retrieval, often conducted at facilities like Delhi's new Digital Flight Data Recorder and Cockpit Voice Recorder Laboratory, involves meticulous repairs and analysis, providing insights within 24 hours, though full investigations may take weeks. Limitations And Challenges Although critical, black boxes are not infallible. The NTSB commented that the Jeju Air plane crash in South Korea (December 2024) lost vital data from the last minutes of the flight. Likewise, Malaysia Airlines Flight 370's black box was never found (March 2014), and detection issues were exposed. The Aircraft Accident Investigation Bureau (AAIB) will be depending on the Delhi lab to inspect the recovered black box in the case of the Air India crash, hoping to explain the catastrophic failure.

Samsung's One UI 8 Voice Recorder update cuts back on AI clutter
Joe Maring / Android Authority TL;DR Samsung's Voice Recorder update for One UI 8 focuses less on AI tools and more on recording and playback. The app is designed for early One UI 8 builds, but also works on One UI 7 if manually installed. AI transcription, summary, and translation are still available, but no longer dominate the interface. At a time when AI seems to be taking over every app you use — expect to see a lot of it at Google I/O later — Samsung might be quietly dialing it down, at least a little. A new version of the Voice Recorder app, designed for One UI 8, offers a glimpse at a cleaner, more restrained approach to Galaxy AI. As spotted by SammyGuru, this updated app version is part of a leaked One UI 8 build already circulating online. Interestingly, the app also runs on current One UI 7 devices if you sideload the APK, giving more users a chance to check out the changes ahead of the official OS update. The most obvious tweak is to the layout. Instead of foregrounding its AI capabilities, the app now puts the focus back on what it was originally designed for: recording and playing back voice notes. In the current version, the transcription and summarization tools are front and center, with playback controls squeezed into a smaller space. Now, those AI tools are grouped into a Galaxy AI menu at the top of the screen, and the transcribe button is given less prominence. It's a simple UI shift, but one that may speak volumes. While some embrace AI, many people get frustrated by it being wedged into every corner of their devices. Samsung is testing a more subtle approach, which might indicate that it's taking the hint. The transcription, summarization, and translation tools are still available for those who want them, but they no longer take over the interface. Got a tip? Talk to us!

Helicopter in mid-air collision with flight 5342 may not have heard key instruction
WASHINGTON (KSNW) – The National Transportation Safety Board held a media briefing Friday on the mid-air collision near Ronald Reagan Washington National Airport last month. On Jan. 29, an American Airlines Flight 5342 from Wichita to Ronald Reagan Washington National Airport and a U.S. Army Sikorsky UH-60 Black Hawk helicopter collided midair over the Potomac River. Sixty-seven people were killed. NTSB Chairwoman Jennifer Homendy said the recording from the Black Hawk helicopter cockpit suggests the crew may have missed the key instruction just before the Jan. 29 collision. 'The instruction from ATC (Air Traffic Control) was to pass behind the CRJ (plane). That transmission was interrupted. It was stepped on. We do not have evidence on the CVR (Cockpot Voice Recorder) of the Black Hawk that they may have not received the 'pass behind the' because of the mic key. They were communicating with air traffic control at the time,' Homendy said. Homendy said the helicopter was on a check flight that night when the pilot was being tested on the use of night vision goggles and flying by instruments. Investigators believe the crew was wearing night vision goggles throughout the flight. More than 200 contamination sites in Sedgwick County It was the deadliest plane crash in the U.S. since 2001. Much of the attention since the collision has focused on the helicopter's altitude and whether it could have been flying too high. Copyright 2025 Nexstar Media, Inc. All rights reserved.
