The disappearance of Malaysia Airlines Flight 370 (MH370) on March 8, 2014, remains one of the greatest mysteries in aviation history. The plane, a Boeing 777, vanished from radar en route from Kuala Lumpur, Malaysia, to Beijing, China, with 239 passengers and crew on board. In the years since, investigators have analysed various factors, including fuel calculations, to determine the aircraft's possible flight path and final location. The amount of fuel on board MH370 has been a subject of discussion and speculation, with some questioning whether extra fuel was loaded and how this may have extended the plane's range and potential landing sites. Official records indicate that the aircraft's take-off fuel was 49,100 kg, with an estimated 41,500 kg remaining after 41 minutes of flight.

What You'll Learn
The plane's fuel weight was 49,100 kg at takeoff
The amount of fuel on board a plane is typically calculated based on the planned trip fuel, which is estimated using factors such as the fuel type, airframe gross weight, and expected flight duration. In the case of MH370, the planned trip fuel was 37,200 kg, which is significantly less than the amount of fuel the plane actually had on board. This discrepancy has led to speculation about whether the pilots requested extra fuel or if there was an error in the fuel calculation.
Some people have suggested that the pilots may have asked for additional fuel to account for potential bad weather or the possibility of having to divert from the planned route. However, officials from Malaysia Airlines claimed that the pilots did not request any extra fuel. It is also possible that there was an error in the fuel calculation or that the amount of fuel added was not accurately recorded.
The amount of fuel on board MH370 is significant because it affects the potential range of the aircraft and, consequently, the possible locations of the crash site. Investigators have adjusted the search zone multiple times based on new theories and calculations regarding the plane's fuel consumption. For example, in October 2016, the Australian-led search team shifted the search area 1,100 km to the northeast after determining that the plane was likely going faster and using more fuel than initially thought. This suggested that the plane would have run out of fuel sooner and crashed in a different location than previously estimated.

MH370 was estimated to have 41,500 kg of fuel after 41 minutes
The disappearance of Malaysia Airlines Flight 370 (MH370) on 8 March 2014 remains the single deadliest case of aircraft disappearance and is widely regarded as the greatest mystery in aviation history. The aircraft was tracked by the Malaysian military's primary radar system for an hour after it was lost from ATC's secondary surveillance radar screens, during which it deviated from its planned flight path, crossing the Malay Peninsula and the Andaman Sea.
The focus of the investigation has been on the pilot, Captain Zaharie Ahmad Shah, but so far, no information implicating him or anyone else has emerged. One theory is that the plane was hijacked, and extra fuel was added to extend its flight range. Another theory is that the pilot or hijackers flew the plane to 45,000 feet to kill the passengers, then shadowed another plane to evade radar, using the extra fuel to land elsewhere.
The actual amount of fuel added to the plane should have been noted on the fuel sheet and billed to the airline company. According to the MH370 ATC flight plan dated 7 March 2014, the take-off fuel recorded was 49,100 kg. Investigators estimated that the aircraft would have had 41,500 kg of fuel remaining after 41 minutes of flying from KLIA to IGARI. The last position report transmitted via ACARS at 17:07:29 UTC recorded fuel of 43,800 kg at 35,004 ft altitude.
The search for MH370 has been challenging due to the vast and remote stretch of ocean involved, with rapidly changing weather conditions. The search zone has been moved based on new theories about the plane's fuel consumption, suggesting that the plane would have burned more fuel in the opening stages of its flight and thus would not have made it as far into the Indian Ocean before crashing. Despite searching for over two years, only scattered debris has been found on the shores of the Indian Ocean.

The plane's fuel burn rate was 140 kg per mile
The Boeing 777-200ER aircraft, operating as Malaysia Airlines Flight MH370, took off with a full fuel load for its planned journey from Kuala Lumpur to Beijing on March 8, 2014. The plane's fuel capacity is approximately 174,000 litres or 130,000 kg of fuel, which is a significant amount and provides a substantial range for long-haul flights.
Now, let's focus on the statement, "The plane's fuel burn rate was 140 kg per mile." This indicates that for every mile the aircraft travelled, it consumed 140 kilograms of fuel. This burn rate can be influenced by various factors, including the weight of the aircraft, its speed, altitude, and external factors such as headwinds or tailwinds.
At this burn rate, the plane would have consumed fuel at a rapid pace. For example, in just one hour of flight time at a constant speed, the aircraft would have burned approximately 6,720 kilograms of fuel (considering a speed that covers 48 miles in an hour). This equates to a significant portion of the total fuel load.
Given the plane's fuel burn rate, it is likely that the aircraft could not have ventured extremely far beyond its last known position. This burn rate, coupled with the plane's initial fuel load, helps investigators and analysts piece together potential flight paths and the possible distance the aircraft could have travelled after its last confirmed location. This information is crucial in narrowing down the search areas and understanding the scope of the search operation.

The plane was flying at 35,004 ft when it disappeared
The disappearance of Malaysia Airlines Flight 370 (MH370) remains the single deadliest case of aircraft disappearance and is widely regarded as the greatest mystery in aviation history. The plane vanished from radar on March 8, 2014, while en route from Kuala Lumpur International Airport in Malaysia to Beijing Capital International Airport in China.
The last position report transmitted by MH370 recorded a fuel weight of 43,800 kg at a high altitude of 35,004 ft. The plane was likely flying at this altitude when it disappeared, as indicated by the last ACARS broadcast. At this altitude, the plane's fuel weight would have decreased during the burn, and the exact flight parameters, including turns and the end-of-flight scenario, are unknown.
The amount of fuel on board a plane is typically calculated based on the planned trip, and for MH370, the take-off fuel recorded was 49,100 kg. This included an estimated fuel reserve for possible diversions or emergencies. However, the actual fuel consumption and burn rate can vary depending on factors such as speed, altitude, and weather conditions.
In the case of MH370, investigators initially estimated that the plane had enough fuel to reach the southern Indian Ocean, with its last location far from any possible landing sites. However, later analyses suggested that the plane was travelling faster and consuming more fuel than previously thought, which would have shortened its possible distance travelled before running out of fuel.
The focus of the investigation has included various theories, such as hijacking, pilot sabotage, or a crisis that incapacitated the crew, leading to the plane flying on autopilot until it exhausted its fuel. Despite extensive searches, only scattered debris has been found in the Indian Ocean, and the specific location and cause of MH370's disappearance remain a mystery.

The plane's final location was far from possible landing sites
The disappearance of Malaysia Airlines Flight 370 (MH370) on 8 March 2014 is regarded as the greatest mystery in aviation history. The aircraft last communicated with air traffic control (ATC) 38 minutes after takeoff over the South China Sea. The plane was tracked by the Malaysian military's primary radar system for an hour, deviating westward from its planned flight path, crossing the Malay Peninsula and the Andaman Sea.
The exact amount of fuel on board the aircraft is uncertain. The take-off fuel recorded was 49,100 kg, and the aircraft would have had 41,500 kg of fuel remaining after 41 minutes of flying. The last position report transmitted via ACARS showed 43,800 kg of fuel at 35,004 ft altitude. However, there are speculations that the pilots requested extra fuel, which could have extended the flight range.
The final location of MH370 was far from any possible landing sites. Analysis of satellite communications concluded that the flight continued until at least 08:19 and flew south into the southern Indian Ocean. Despite extensive searches, no evidence of the aircraft has been found. The official search operation was suspended in January 2017, and subsequent searches by private companies have also been unsuccessful.
The most likely impact location was estimated to be around 35.6°S 92.8°E, and the underwater search area was narrowed to 25,000 km2 (9,700 sq mi). The search has involved ships and aircraft from multiple countries, and satellite imagery has been used to aid the efforts.
The mystery of MH370's disappearance persists, and the aircraft's final resting place remains unknown. The Malaysian government has not closed the case and remains open to future searches if credible information about the aircraft's location emerges.
