Their main interest is regarding the content of your carry on luggage rather than the size.
It featured a photo like the one above and a caption that stripping out the swear words read: Why do I have a 50 lb. Well, we've done the calculations and the results are quite surprising - even a little disturbing.
They perhaps back up Samoa Air's decision to be the first airline in the world to charge customers by body weight as well as luggage weight in Some industry sources claim this concept could be the future for air fares.
Aircraft carrying a space shuttle Let's start with that Shuttle Orbiter, whose dry weight is around 78, kilos Like most airlines, we'll keep all the numbers metric: To equip the aircraft for its new role, Boeing stripped out most of the main cabin fixtures and insulation though keeping a few first class seats for NASA passengersadded some mounting struts and beefed up the fuselage.
They also added some extra vertical stabilizers to keep the thing flying straight with the Orbiter on top, as well as some more powerful engines.
They even added an escape tunnel system for the flight crew although they had to remove it later, after it became clear that the escape trajectory was unlikely to take the hopeful parachutist much further than the fan blades of one of the inboard engines.
Aircraft fuel calculations So let's look at the basic data for a Boeing in airline service. Maximum takeoff weight iskilograms. That's the total weight that the wings and engines can lug into the air.
But the airframe weight in airline trim iskg. But that's before you've added fuel. Jet aircraft are incredibly thirsty and therefore require huge amounts of fuel.
In order to calculate the weight of a maximum fuel load, we need to find out what kind of fuel was used and then apply a conversion factor. Your basic common or garden jet fuel is Jet A or Jet A1, with a density on the ground of 0. Thus the weight of a full fuel load is just under Suddenly, that lifting capacity isn't looking so generous after all.
Now we're left with actual carrying capacity of a mere 23, kilos. You can deduct a further kilos for the weight of a three man flight crew though a three woman flight crew would only weigh kilos.
All of which explains why even the stripped out SCA had a very short range, having to go coast to coast in hops of little more than 1, miles at a time with the shuttle on top. Weight and load calculations And how does that net payload of The short answer is - it doesn't.
An average 40, items of inflight catering and other supplies: Airlines don't like to make passengers get on the scales at the Check In Desk, so they work to a basic rule of thumb of 79 kg per male and Children up to 12 are counted as 34 kilos each all year round.
In airline trim, the B could carry passengers in two classes or in three classes. Plainly that first configuration isn't going to work for London to LA, with a basic passenger weight assuming male, female, 32 minors of more than 28 tonnes, even in short sleeved shirts and summer frocks.
In three class configuration, we might have better luck. Now the weight of passengers comes down to just over 17 tonnes male, female and 26 minors but we're still a little over maximum takeoff weight - with everyone bare-ass naked and without their luggage. Quite apart from preserving decency, that's a major problem because the baggage also weighs a lot.
Then you have the hold bags. We're now around 16 tonnes over weight and will have to offload close to 20, liters of fuel to get airborne. On the next page we look at the baggage capacity of modern aircraft and safety calculations to conclude whether baggage weight matters.
In addition to that, we discuss some of the most infamous plane crashes where baggage weight was found to be a prime cause of the crash.Risk Savvy by Berd Gigerenzer is a very useful book about how to make good decisions under situations involving risk.

Carry on Luggage: Size, Weight and Rules for All Airlines Traveling with a carry on luggage is always challenging since there are many rules to respect, different sizes and weights allowed for each airline.
Scientific tests show that high-antioxidant foods can bolster resistance to damage from the ultraviolet light that promotes sunburn, wrinkles and skin cancer. PREFACE to first edition.
THIS BOOK was to be an autobiography. I was made into a computer fifty years ago. I was the second scientist ever hired by IBM, and I watched the Watsons on Olympus, and Bill Norris and Ken Olsen and Gene Amdahl, and a thousand great commercial and academic figures.
