| Very informative. I just took the liberty of converting your post to units I can read (sorry for the pathological imperialphobia :) ) > Yes: because Samoa Air's fleet aircraft are all Cessna 172s. You are essentially paying for a personal charter flight in a small aircraft, so there are no "averages" there. A single obese passenger can directly increase a flight's payload weight by +100% or more. Not the case with an airliner, where you are averaging across 75-600 people. > In general aviation just because the seat is there doesn't mean you can take off with someone in it. As a rule of thumb, "one seat" is a 68.03 kg person, no luggage, and sometimes that's counting some of your fuel there too. A 2-seat aircraft like the Cessna 152 doesn't take off with full tanks with 2 average adult males onboard even without luggage (163.29 kg full-fuel payload), and it's a struggle to get off the ground with 2 heavier adults even with reduced fuel. > The C172 is a four-seater aircraft, 261.7 kg full-fuel payload (note: less than 68.03 kg per seat!). So with full fuel tanks you will get one pilot, one passenger, and either some luggage/cargo or a child passenger. Maybe a second adult passenger and no luggage if nobody is too heavy (above 79.37 kg average). And an over-water flight in the Pacific is not the trip to take with a reduced fuel load. So you can see how the numbers work out here: the pilot plus one obese adult might literally be the entire payload for the flight. > (Note: a 2003 study from the New Zealand Ministry of Health set their "average" male passenger weight at 84.82 kg without carryon, or 93.89 kg with carryon, and the average female passenger weight at 72.12 kg without carryon or 76.65 kg with. Further, they noted that average passenger weight was increasing at about 2 kg/6.6 lbs per decade.) > source: https://www.caa.govt.nz/pubdocs/2003_pax_weight_survey.pdf |
