Fuel Matrix, a company based in Berkshire, England, is, reportedly, in talks with airlines in the U.K. over the deployment of “pressure pads” in airports that would discreetly weigh passengers as they pass through the check-ins. The data would be sent directly to the flight deck so pilots could know exactly how much fuel does the plane need, and it’s eventually done to cut costs and carbon emissions.
There have been a number of ideas on how to measure the weight of the passengers. One of them was installing pressure pads at self-service baggage drops, or at the security body-scan machines.
Airline companies need to carefully calculate how much fuel the plane needs for the flight, and heavier the load, the more fuel the plane needs.
Accordingly, using more fuel is more expensive, and it produces more carbon emissions.
Airlines currently calculate the total weight of the passengers using an estimate based on age and gender, and they average 88kg (194lbs) for men, 70kg (154lbs) for women, and 35kg (77lbs) for children.
Fuel Matrix, however, believes that airlines use more fuel than they actually need to with these calculations.
According to chief operating officer Nick Brasier, most flights carry about 1% more fuel than they need to, which costs a lot of money.
However, airlines have been trying to weigh passengers before, as Uzbekistan Airways announced in 2015 that they would weigh passengers at check-in desks, and it is also said that some overweight people would be excluded from busy flights on smaller planes if limits are exceeded.
