Interested PAX here. I always wondered what the average figures for calculating passenger weight are. Is that a global standard?
In the USA it's 190 pounds in the summer and 195 in the winter. There are separate male/female numbers of 200/205 and 179/184 but everyone I know just uses the average. Children up to 12 are 82/87 but most times they are just counted at 190/195 also. Sometimes when trying to carry a jumpseating crewmember on a weight restricted flight I've heard Captains asking if any of the pax are children. Two kinder would allow the jumpseater.
No idea if the numbers are standard around the world. The FAA raised the numbers several years ago after a Beech 1900 crash in CLT. They said they would monitor American weights and adjust as necessary.
