As flight 143, a twin engine 767, was go throughing over Red Lake on its was

to Edmonton, Canada, the left forepart fuel pump warning light went on. There were

a few possibilities for this to go on, such as the fuel pump weakness, a fuel

line clogging, or a empty fuel armored combat vehicle. The former two were easy dealt with,

since the plane could wing without one fuel pump. However, the last possibility

was dismaying. After a few proceedingss, the 2nd fuel pump in the left wing

began to blast. It would be excessively much of a happenstance for two fuel pumps to

independently fail, or two fuel lines to independently choke off, so it was evident

that the left armored combat vehicle was out of fuel. Quickly, the pilots decided that acquiring to

Edmonton was out of the inquiry. The nearest big airdrome was at Winnipeg, so

they radioed in front and changed their class. In a few proceedingss, all four of the

fuel pumps had failed. The worst possible intelligence, they were out of fuel. In a

few more proceedingss the engines stopped running, and all of the high tech

instruments became useless.

They realized that they could non even do it to Winnipeg. Their lone

opportunity was an Bachelor of Arts

andoned to a abandoned Air Force flight strip. Unfortunately, the

flight strip had been converted to a race path, complete with race autos, fencings,

and witnesss. The 767 clang landed, and, fortuitously, no 1 was killed.

Their were many lending factors that made this plane run out of

fuel. First of wholly, the computerized fuel gage was non working, and a

care worker said, falsely, that the plane was still certified to wing.

To mensurate the sum of fuel staying, they use a trickle stick method. They

discovered that their was 7 682 litres in the armored combat vehicle. However, they had ever

measured fuel in the yesteryear as lb, while the 767 consumed fuel in kgs.

The trickle sticks did non show the sum of fuel in lbs or kgs, but

in litres. It seems to be a simple affair of transition to get a the reply.

All they needed to cognize was how many kgs were in a litre. Person said

1.77, and they calculated the value they needed. However, the transition of

1.77 was non Kilograms per litre, but lbs per litre. The existent value it.

803. They were off by more than 50 % . This job would hold been avoided if

they had kept path of the units during the transition. That is why it is

ever of import to maintain path of the units.
