The following calculation represents what the worker did prior to the flight: 7,682 liters x 1.77 lb/L= 13,597 lb (where d=1.77 lb/L) 22,300 kg - 13,597 kg= 8,703 kg = mass of additional fuel required 8,703 kg / (1.77 lb/L) = 4,917 = volume of additional fuel required Based on your calculations above and the worker’s calculation, (1) where was the mistake made? And (2) how much more fuel would have needed to be added than the worker added to successfully complete the flight ?

The following calculation represents what the worker did prior to the flight: 7,682 liters x 1.77 lb/L= 13,597 lb (where d=1.77 lb/L) 22,300 kg - 13,597 kg= 8,703 kg = mass of additional fuel required 8,703 kg / (1.77 lb/L) = 4,917 = volume of additional fuel required Based on your calculations above and the worker’s calculation, (1) where was the mistake made? And (2) how much more fuel would have needed to be added than the worker added to successfully complete the flight ?
The Refueling Error: The following calculation represents what the worker did prior to the flight: The Importance of Units: The Gimli Glider Overview of the Case: (where d-1.77 lb/L) 7,682 litres x 1.77 lb/L = 13,597 lb 22,300 kg - 13,597 kg = 8,703 kg = mass of additional fuel required 8,703 kg + (1.77 lb/L) = 4,917 litres = volume of additional fuel required Based on your calculations above and the worker's calculation, (1) where was the mistake made? And (2) how much more fuel would have needed to be added than the worker added to successfully complete the flight? The switch to the metric system from imperial units began in earnest in Canada in the 1970s. By the 1980s, the aviation sector in Canada was in the process of converting to the metric system. Air Canada Flight 143 was a flight scheduled on July 23, 1983 to fly between Montreal and Edmonton. On AIR CANADA that day, at an altitude of 41,000 feet, only midway through the flight, the plane ran out of fuel. How did this happen? Could it happen again? How could it have been avoided? Biredeci- On work, CC Y-SA10 The Refueling Calculations: At the time of this flight, some flights were using metric units and other flights were using imperial units. 767 planes, like the one used on Air Canada Flight 143, were using the metric system. The pilot calculated that the flight would require 49,200 Ibs of fuel. If there are 2.20 lb/kg, how many kg of fuel were required? 9 20ot 2.20 Jo ng The Outcome: On the day in question, the plane ran out of fuel midair, far away from the final destination. Luckily, pilot was a skilled glider pilot, too, and was able to successfully navigate the plane to a runway and la without loss of life. However, had the pilot not been a trained glider pilot or had an appropriate land zone not been found in time, such a calculation error could have been catastrophic! =22,3163 63ng A worker in charge of helping with the refuel checked and found that there were 7,682 liters of fuel in the tank already. Given that jet fuel has a density of approximately 0.804 kg/L, how. many kg of fuel were already in the tank? 7.682 Lx0.804 ng/L Video Link: https://www.youtube.com/watch?v=SjTz-OCECZC Mixups between the metric system (or SI) and other unit systems can cause various mixups, errors issues. Here's a link overviewing a few more examples: https://usma.org/unit-mixups Other Notable Historic Unit Conversion Mixups: Based on the two calculations above, what amount of fuel (in kg) needed to be added to the tank? 22,803-63 - 6.1763= 22, 881.43 ng Always show measured numbers as magnitudes and units. Always track your units when performii calculations! The Moral of the Story: Fuel is transferred using a device that measures volume in liters-how many liters of fuel needed to be added?
