The Approach and Landing Sequence of Flight 605

Alright guys, let's get into the nitty-gritty of what happened during the approach and landing of Indian Airlines Flight 605. The flight departed from Madras and was cruising normally until it began its descent towards Bangalore. As the Boeing 737-200 entered the final stages of its journey, things started to go downhill, quite literally. The crew reported that they were established on the Instrument Landing System (ILS) approach for runway 09. However, the aircraft began to descend much lower than the intended glide path. This deviation was not immediately corrected. We're talking about a significant loss of altitude, which is incredibly dangerous during a landing. The pilots, under pressure and possibly disoriented or misinterpreting their instruments, continued their descent. The Air Traffic Control (ATC) at Bangalore did issue altitude call-outs, but it seems these warnings weren't fully heeded or understood in the heat of the moment. The aircraft's Ground Proximity Warning System (GPWS) did activate, blaring alarms that should have signaled an immediate go-around. Yet, the crew did not initiate a go-around. This is a critical point – the GPWS is a last-resort safety device designed to prevent terrain impacts. Its activation indicates a dire situation. The lack of a timely go-around is one of the most debated aspects of the accident. Investigators looked into why the pilots didn't react as expected to the warnings. Possible reasons explored include the crew's fatigue, stress, misinterpretation of the altimeter readings, or even issues with the ILS equipment itself, though the latter was largely ruled out. The terrain in the vicinity of Bangalore airport is also somewhat undulating, and at the low altitudes the aircraft was flying, this posed a significant risk. The Boeing 737-200, with its registration VT-EAC, was flying towards a complex environment, and the precision required for a safe landing was compromised. The crash occurred just short of the runway, in a wooded area, demonstrating how close they were to achieving their destination but ultimately failing due to the descent profile. The sequence of events painted a picture of a crew struggling to maintain control and awareness during a critical phase of flight. The crew consisted of a captain and a first officer, and the investigation delved into their interactions and decision-making processes. It's a stark reminder that even with advanced technology, human factors play an enormous role in aviation safety. The flight path data and cockpit voice recorder (CVR) information were crucial in piecing together the final moments. The CVR revealed conversations and alarms that helped investigators understand the crew's state of mind and the unfolding emergency. The story of this approach is a classic case study in aviation safety, highlighting the dangers of controlled flight into terrain (CFIT) when situational awareness is lost. The pilots were likely trying to correct their position, but their actions led them further into danger. The final impact was devastating, shattering the aircraft and claiming the lives of so many aboard. The wreckage was scattered over a wide area, indicating the high speed and forces involved in the crash.

The Investigation and Probable Cause of the Crash

So, what did the experts find out, guys? The investigation into Indian Airlines Flight 605 was thorough and involved international aviation safety bodies. The primary goal was to determine the probable cause of the crash and to identify any contributing factors to prevent future incidents. The investigation team meticulously analyzed wreckage, flight data recorder (FDR) information, cockpit voice recorder (CVR) recordings, and witness accounts. One of the key findings revolved around the crew's loss of situational awareness during the final approach. It appeared that the pilots were not fully aware of their precise altitude and position relative to the glide path. Several factors might have contributed to this:

• Altimeter Errors: While not definitively proven as the sole cause, there was speculation and examination into whether the altimeters were functioning correctly. However, subsequent checks indicated they were likely accurate.
• Misinterpretation of ILS: The crew might have misinterpreted the Instrument Landing System (ILS) indications, leading them to believe they were higher than they actually were.
• Non-adherence to Standard Operating Procedures (SOPs): The Boeing 737-200's crew did not initiate a go-around despite multiple warnings from the Ground Proximity Warning System (GPWS). This failure to adhere to standard procedures in an emergency is a critical aspect of the investigation.
• Crew Resource Management (CRM): The investigation also looked into the dynamics between the flight crew. Effective CRM is vital, ensuring that both pilots are actively involved, communicating clearly, and challenging each other's actions when necessary. The CVR data was instrumental in assessing the CRM on board Flight 605.
• Environmental Factors: Although the weather was reported as adequate for landing, the specific terrain around Bangalore airport could have played a role, especially if visual cues were lost or misinterpreted.

The official report concluded that the probable cause was the crew's failure to maintain the required altitude and correct glide path during the approach, leading to a controlled flight into terrain (CFIT). The tragedy of Flight 605 was a complex event, likely resulting from a combination of human factors, procedural deviations, and possibly a subtle degradation of situational awareness. The report emphasized the importance of robust training in CRM and emergency procedures, particularly concerning the timely execution of a go-around. The investigators stressed that the GPWS warning should have been the trigger for immediate action, and its failure to prompt a go-around was a critical error. The crash near Bangalore served as a harsh lesson for Indian Airlines and the broader aviation community. It underscored the need for continuous vigilance, rigorous training, and a culture that prioritizes safety above all else.
