The Tragic Story of FlyDubai Flight 981: A Lesson in Aviation Preparedness and Response
Introduction
In aviation, thorough preparation and briefings are cornerstones of safety. However, what happens when unforeseen circumstances disrupt the carefully laid plans of flight crews? This was tragically illustrated in the events surrounding FlyDubai Flight 981, which occurred on March 18, 2016. The flight from Dubai to Rostov-on-Don was plagued by weather-related challenges and ultimately ended in disaster. This article delves into the series of events leading to the crash, highlighting key factors and lessons learned.
Pre-Flight Preparations and Challenges
Part 2/9:
On the evening of March 18, 2016, the flight crew of FlyDubai Flight 981 gathered at the Dubai airport, briefing for their scheduled flight to Rostov-on-Don in Russia. The flight was set to depart at 21:45 UAE time, with an anticipated arrival approximately four hours later. However, the crew soon noted that adverse weather conditions were forecasted for their destination, including strong winds and thunderstorms due to a cold front.
Part 3/9:
Both pilots had ample experience and prior rest, yet the weather's unpredictability was a significant concern. They also had to navigate unique pilot regulations for flying in Russia, as the use of meters instead of feet and QFE (pressure relative to airport elevation) settings often posed additional complications for non-Russian crews. Nevertheless, the crew decided to proceed since the weather conditions met minimum requirements for landing.
The Flight and Unexpected Turbulence
Part 4/9:
The flight took off without incident, but shortly after reaching cruising altitude, things began to take a turn for the worse. Around an hour prior to descent, the autopilot was transitioned to the different systems, a typical move before preparing for landing. The pilots communicated with the Rostov control tower for updated weather information and received alarming reports of severe turbulence on the approach.
Despite being unaware of an earlier significant meteorological report warning of severe turbulence, the crew found themselves confronted by difficult weather conditions in the Rostov area. As they commenced their descent, they encountered wind shear, defined as abrupt changes in wind direction or speed, which can be particularly dangerous when close to landing.

The Go-Around Decision: A Critical Junction
As FlyDubai Flight 981 approached for landing, the pilots were faced with turbulent conditions. The captain opted to maintain control without the autopilot, a common practice in turbulent weather, but this decision became critical moments later. Just after breaking through the clouds and visualizing the runway, the crew was warned of wind shear. Reacting swiftly, the captain initiated a go-around maneuver, pushing forward the thrust levers to the maximum, signaling an immediate need to escape the dangerous situation.
Part 6/9:
The first officer correctly called out for the captain to manage the flaps and gear, but confusion soon ensued. The captain, focused on the go-around procedure, mistakenly began changing configurations, which led to further complication in an already precarious situation.
Disorientation and the Fatal Crash
In the tumultuous moments that followed, the captain became overwhelmed. The airplane was subjected to severe pitch changes, eroding the crew's situational awareness. A rapidly increasing airspeed, driven by a high thrust setting and extended flaps, put the aircraft in a critical condition.
Part 7/9:
Despite attempts to communicate and mitigate the escalating crisis, the captain struggled against the disorientation exacerbated by a phenomenon known as somatogravic illusion, where the pilots' body senses intersect with the aircraft's performance in a disorienting manner. Ultimately, the aircraft pitched down dramatically and crashed, resulting in the loss of all 62 lives aboard.
Investigation and Recommendations
The investigation into FlyDubai Flight 981 revealed that spatial disorientation, failure to adequately respond to the weather-induced go-around, and communication breakdown were the primary factors in the disaster. It emphasized the need for thorough training on upset recovery and a better understanding of aircraft systems, particularly in conditions of high stress.
Part 8/9:
Following the incident, 26 recommendations were made, several focusing on improved pilot training in upset recovery and ensuring a more competent understanding of aircraft behavior during extreme conditions. The incident underscored the importance of maintaining situational awareness and adhering to set procedures in aviation, especially when unexpected challenges arise.
Conclusion
Part 9/9:
The crash of FlyDubai Flight 981 serves as a somber reminder of the complexities of aviation and the vital importance of effective communication, situational awareness, and thorough training. In moments of crisis, the outputs of careful planning can be undone by unforeseen variables. As the aviation community continues to learn from such tragedies, the hope remains that these lessons will enhance future safety for passengers and crew alike.
