Why Did Flight 174 Run Out of Fuel?

Flight 174, a Canada World Airways Boeing 767, ran out of fuel on July 23, 1983, while en route from Montreal to Edmonton, Canada. The incident was a significant aviation accident that raised questions about the causes of fuel exhaustion and the measures taken to prevent such incidents. In this article, we will explore the reasons behind the fuel shortage and the subsequent investigation.

Pilot Error

One of the primary reasons for the fuel shortage was pilot error. The pilots, Captain Bob Pearson and First Officer Maurice Quintal, made a mistake in calculating the fuel requirements for the flight. They used the wrong conversion factor, converting the fuel requirements from liters to pounds, which resulted in a significant underestimation of the fuel needed. This mistake was compounded by the fact that the pilots did not double-check their calculations before departing.

Incorrect Fuel Calculation

Here is a breakdown of the incorrect fuel calculation:

• Liter conversion: The pilots used 0.45 kilograms per liter instead of 0.63 kilograms per liter, which is the correct conversion factor.
• Fuel calculation: The pilots calculated the fuel requirements based on the incorrect conversion factor, resulting in an underestimation of the fuel needed.

Investigation and Findings

The investigation into the incident was conducted by the Transportation Safety Board of Canada (TSB). The findings of the investigation highlighted several key factors that contributed to the fuel shortage:

• Pilot error: The pilots’ mistake in calculating the fuel requirements was the primary cause of the fuel shortage.
• Lack of communication: There was a lack of communication between the pilots and the ground crew regarding the fuel calculation.
• Inadequate training: The pilots did not receive adequate training on fuel calculations and conversion factors.

Consequences

The consequences of the fuel shortage were severe:

• Emergency landing: The pilots were forced to make an emergency landing at Gimli, Manitoba, without sufficient fuel.
• Passenger evacuation: The passengers had to be evacuated from the plane using emergency slides.
• Investigation and reforms: The incident led to a thorough investigation and reforms in the aviation industry, including improved training and procedures for fuel calculations.

What Can We Learn from the Incident?

The incident highlights the importance of:

• Attention to detail: Pilots must be meticulous in their calculations and conversions to avoid errors.
• Effective communication: Pilots and ground crew must communicate effectively to ensure that all necessary information is shared.
• Training and procedures: Airlines must provide adequate training and procedures for pilots to ensure that they are prepared for emergencies.

Conclusion

The incident of Flight 174 serves as a reminder of the importance of attention to detail, effective communication, and adequate training in the aviation industry. The mistake made by the pilots was a significant one, and it highlights the need for vigilance and caution in the calculation of fuel requirements. By learning from this incident, we can reduce the risk of similar incidents occurring in the future.
