 Weighing Airliners

 Hello, I was wondering how before each flight the weights of the aircraft is devired. Do they just take the amount of pax and times it by the standard and the fuel/cargo load and add it to the operating weight, or do they have some mechanism that can weigh itself inside the airplane? I have heard some pre-flight 747 cockpit conversations, and the flight engineer always reported before the checklist, "we weigh...." Sincerely, covert

 Standard weights apply generally to domestic flights (in USA) - while overseas actual weight of bags is verified before loading... xxx I have a personal rule of thumb, over and above "regulations" and "procedures" - each adult passenger (his body + his baggage) weighs a total of 100 kilos as far as I am concerned, children 2 to 12 age go for 50 kilos, and infants are not accounted for weight... xxx So if an agent tells me that I have 330 passengers, 20 children and 5 infants, I quickly compute 330x100 = 33,000 kilos, 20x50 = 1,000 kilos... bottom line is my passengers and baggage total is 34,000 kilos... and I know that I have 355 passengers on board... our plane operating weight includes crew... we know that number... we just have to add the weight of fuel... xxx Surprisingly, with their superior scales, and advanced computations, they will find that the weight is 33,315 kilos, next day 34,160 kilos... 34,000 close enough for me... takes me 30 seconds to compute, for them - 1 hour... xxx These standard numbers never failed me, no matter where I am... and my plane does not feel different with 500 kilos error, nor can I see the different speeds on the chart... shall V2 speed be 174.2 knots or 174.4 knots, beats me, I know you guys fly better than me (with your FS practice), for me it is plus or minus a couple of knots, the best you can expect from me - sorry...   (s) Skipper

 Thank you so much skipper, it is pretty intiguing that a simple mental calculation can produce near to the same result as a multi-million dollar technical innovation... Sincerely, covert by the way is there any case where the situation entails a "screw it" we have to put the plane on the scale?

 If you are carrying like a football team.. situations like that you will want to go for a higher weight per person than standard.

 Actually, Covert, Skipper is just pulling your leg. What he meant to say was that they weigh in at scales, just like boxers do.

 Dear Leezyjet - All you statements are fully correct - same applies for my airline... My "quick and dirty" computations are done with the only purpose of a crosscheck of the numbers presented by traffic agents... If my own number is 33,500 payload, and they show a loadsheet of 21,783 kilos, I immediately question "their mistake", unless our passengers are like the 7 dwarfs... xxx Everyone is human, and could make mistakes... I avoid my own by having a mental estimate of the numbers to expect. I had a serious incident once with a cargo aircraft which was loaded with a kilo payload but assumed to be in pounds by a loadmaster who made a grave mistake... xxx My wife is too pretty and young... I do not want her to enjoy my life insurance too early in life... xxx Always smiling   (s) Skipper

 "Technology I doubt will ever surpass the human mind." You haven't read about the winning candidates for the "Darwinian Awards", have you?   So, with the exception of fuel (and oil?), all other weights remain the same for the duration of a flight, I assume? aw

 Well - I understand that some food (beans) get changed into gases... then exhausted through the outflow valves... no wonder they get dirty... xxx So, for landing weight, I instruct the flight engineer to deduct 10 kilos of catering for landing weight... consumed by passengers with good metabolism... xxx Nice to know that some contrails have perfumes...

 747Skipper, Think I misinterpreted your original posting. I thought that you were having a dig at the groundstaff for being slow. Yes alot of f/deck crews do their rough calculations as you say so they know approx what to expect on the loadsheet. my bad....   We are assessing the standard bag weights at the moment due to a couple of incidents where our a/c nearly didn't get airborne out of LAX, as they were heavier than expected due to standard bag weights being used.

 At my airline we use 25 pounds for bags on domestic flights and 35 pounds for international flights, pax weigh 180 pounds in summer and 185 pounds in winter. We use the actual weight of cargo and mail.

 I have always wanted to know this: When the passengers eat the food does the a/c weight change? Don't the passengers (and the toilet tanks) just get heavier by the same amount?

 Yeah the numbers that we used to use when I worked for Reeve, if my memory works is.... 170lbs summer weight 175lbs winter weight. 35lbs per bag. 60lbs per duffel bag, you know those big army ones. Freight and mail used their actual weights either from our scale or the post offices.
