Airplane passengers could be weighed before boarding their flights in the future in a bid to reduce fuel wastage and cut costs.
Currently, airlines use an average weight for men, women and children to calculate the amount of fuel they need on each flight.
However, the guide weights used of 13.8 stone for a man, 11 stone for a woman and 5.5 per child lead to excess fuel being used and burned during flights.
Tech firm Fuel Metrix has created a pressure pad device that could weigh individual passengers at the airport check-in desks.
That data could be communicated to the airline so they know how much weight they will be carrying, and in turn, how much fuel they will need.
Fuel Metrix chief operating officer Nick Brasier said: “We’re not suggesting people should stand on the scales, but airports could fit ‘pressure pads’ in the self-service bag drop area in front of each screen.
“After the bag has been checked in, the system can ask, ‘Are you standing on the pressure pad?’
“If the passenger taps ‘Yes’, then the weight can be recorded and passed confidentially to the airline.”
Brasier explained that most flights carry about 1% more fuel than they need. The weight of this excess fuel causes the plane to burn about 0.3% – 0.5% more fuel than necessary.
