But the numbers from the scales won’t be flashing up for all to see. There will be no visible display anywhere,the airline promised,and the weigh-in data will remain anonymous even to airline staff.
“We weigh everything that goes on the aircraft — from the cargo to the meals onboard,to the luggage in the hold,” said Alastair James,a load control improvement specialist for the airline,in a statement. “For customers,crew and cabin bags,we use average weights,which we get from doing this survey.”
Indeed,the numbers are required by the nation’s industry watchdog,the Civil Aviation Authority.
Under the authority’s rules,airlines have various options to estimate passenger weight. One option is to periodically carry out surveys like Air New Zealand is doing to establish an average weight. Another option is to accept a standard weight set by the authority.
Currently,the authority’s designated weight for people 13 and over is 86 kilograms,which includes carry-on luggage. The authority last changed the average passenger weight in 2004,increasing it from 77 kilograms.
Health statistics show New Zealanders are becoming heavier. The latest national health survey put the adult obesity rate at 34 per cent,up from 31 per cent a year earlier. Childhood obesity rates increased to 13 per cent,up from 10 per cent a year earlier.
