Will civil aviation become safer and more environmentally
friendly if we precisely know how heavy each paying passenger is?
By: Ringo Bones
Nick Brasier - chief operating officer of the Berkshire-based
start-up technology company - called Fuel Matrix claims that in the future
every airline passenger will be weighed in order to make civilian air travel
much safer and much more environmentally friendly that it is at present. And if
Mr. Brasier’s discrete method of weighing passengers becomes mandatory, it
could also slash ticket prices. Does Mr. Brasier’s Fuel Matrix really have the
potential to transform civil aviation for the better?
Ever since Al Gore’s An Inconvenient Truth hit the movie
theaters and people everywhere became conscious about the size of their carbon
footprint, environmentalist had been, more or less unfairly, pointing their
finger at civilian air travel for their excessive carbon dioxide emissions.
Even though fossil fuel companies produce way, way more carbon dioxide than the
global airline industry, any schemes that results in significant reduction of
carbon dioxide emissions by airline companies seems to be only of political value
at best, but as they say, every little bit helps.
The resulting safety improvements and operating cost reductions
may be more of interest to the global airline industry than the resulting absolute
reduction of carbon dioxide if Nick Brasier’s Fuel Matrix scheme gets
widespread acceptance. At present, airlines use “assumed mass” – estimating the
total weight of the passengers by using set figures. Typically each passenger
is assumed to weigh 88-kilograms. Mr. Brasier believes that airlines currently
load about one percent more fuel than they actually need and due to the
unforgiving laws of physics and Mother Nature, consequently burn between 0.3
and 0.5 percent more fuel due to the very fact that they carry unnecessary
surplus fuel.
With the global airline industry spending an estimated
200-billion US dollars a year on fuel, the possible saving worldwide is up to
1-billion US dollars per year. In addition, safety will be enhanced by captains
loading extra fuel when it is actually warranted – such as when several rugby
teams are booked on the sane flight. Additional savings can be made by
allocating passengers in the optimum seats to ensure that the aircraft is
properly balanced. At present, pilots sometimes need to apply “trim” during
flight to counter a weight imbalance, a procedure that adds extra fuel burn.
At present, Nick Brasier’s Fuel Matrix is already in
discussion with a number of long-haul airlines, including at least one British
carrier, about deploying the tech firm’s fuel-saving system. Back in 2015,
Uzbekistan Airways said it would weigh passengers before takeoff in an effort
to “ensure flight safety”. Back in 2017, passengers at Helsinki airport were
asked to step on to weighing scales before boarding by Finnair. This was a
largely voluntary scheme to gather data on average passenger weights. Also in
2017, Hawaiian Airlines implemented a new policy on flights to American Samoa
to weigh passengers and assign them to specific seats to ensure weight is
evenly distributed inside the plane.
