manual loadsheet help
Hi
I need help with Manual Loadsheet. Does anybody can help me with that? What does means each item of the manual loadsheet? It there any formula do understand how to make easily one manual loadsheet? If you have some, what I can train I will appreciate, send it to my mail Many thanks Best rgds Rui |
There is a great book from Airbus called getting to grips with weight and balance, at the 2 last chapters of that book they explain every detail you could imagine about the manual loadsheet... I suggest you read that one!
You'll find it here: http://www.smartcockpit.com/data/pdf...nd_Balance.pdf |
help manual loadsheet
Thanks a lot for the link.
I was just having a look, and I need the explanation of all the items what is in the manual loadsheet, like what means Operating Weight. And all the others items Thanks Rui |
Operating empty weight (OEW) is the basic weight of an aircraft including the crew, all fluids necessary for operation such as engine oil, engine coolant, and all the gear required for flight but not including fuel and the payload.

help
Hi and thanks a lot for your answer , but how it can be without fuel, if in the loadsheet it becomes after the fuel ??
Is dow + fuel = Operating Weight If anybody knows a good formula to make it easily , explanation of manual loadsheet Thanks |
Hello. The mix up here is between the 'Dry Operating Weight' (no fuel) and 'Wet Operating Weight' (with fuel). WOW = DOW + take off fuel
The confusion has arisen here because sometimes 'Wet Operating Weight' is just called 'Operating weight'. Any more questions and I'll try and help. |
Rui, which aircraft are you working with? Weight & Balance is my speciality (B747F). I don't quite understand your question.
OEW Operational Empty Weight (includes crew, catering, unusable fuel) + cargo (or pax) = Zero Fuel Weight + Fuel = Ramp Weight (or taxi weight) - taxi fuel = Take Off Weight. TOW - BurnOff = Estimated Landing Weight. If you have some specific questions, I'm happy to help. |

Hello
Thanks a lot for your help If it is possible and I would like to have is, the explanation of each item of the manual loadsheet. Is any where I can go and get it? What means DOI ? How we can calculate that?? Have you got any manual loadsheet of aircraft 737, A320? I would like to train making it? Or there is any where I can go and get it??? Hope you can help Many thanks Rui |
The best will be that you get an AHM (Aircraft Handling Manual) or a GHM (Ground Handling Manual). In these Manuals all the Items are explained.
Also, you will find examples for manuall Loadsheets there. |

Hello thanks a lot for your replay
already found the GHM, where i can find those explanation? Thanks a lot Best rgds Rui |
A search in the archives will find a number of threads which discuss trimsheet design. One example is this one in which we discuss the basics of trimsheet workup design. May provide another slant in addition to the Airbus document .. however the basics are pretty standard so the two will cover much the same stuff.
Best option is to scan and post a copy of the particular trimsheet in question and we can pull it apart to show how it has been designed and drawn up (otherwise called "reverse engineering"). |
DOI stands for Dry Operating Index. It gives an indication of the position of the centre of gravity at dry operating mass. It's really a moment (mass multiplied by the distance from a defined datum) which is usually reduced to a smaller workable number by multiplication with a constant. This makes calculations easier as indexs are just added to each other.
Normally the operator will be able to supply the figures for the dry operating mass and index. For air transport they are required to weigh their Aircraft ever four years and record these figures in a weight schedule. Here's a loadsheet for a CRJ I found with google. If you want I could guide you through it. |
I think the poster really needs a basic and structured course on aircraft dispatching, not picking up snippets on an anonymous forum! He will end up with holes in his knowledge that if he tries to apply this stuff in a professional context will cause danger!

HELP
Hello
I am trying to understand the minimum of Just to make the selection, and sure after words I will be able to take that course. Thanks a lot for the help, and if any body could say any thing I will appreciate Thanks Rui |
Yes Rainboe, I agree with you. We can explain the basics, that's about it.
Rui: as part of your understanding, google or look in the AHM for Mean Aerodynamic Chord, you will see it represented as % MAC. An index is used to determine what the MAC is (index is an easier calculation that MAC). MAC shows the center of gravity on the wing, where 0% is the front, 100% the rear of the wing. There will be a safe range (747F 9% max fwd, 33% max aft). Understanding MAC is critical as the angle on the horizontal stabilisor is set according to weight & MAC. Also know as "trim". Edit: Take a look here, there are some explanations for you. Center of gravity of an aircraft - Wikipedia, the free encyclopedia |
Hi Rui!
If you need any explanation (in portuguese if you want), you may contact me. |
Boas, HI , Please send me all to my mail box
Ola, boa tarde, a muito que estava para te responder,
Se tiveres ou poderes, agradeço que me envies para o meu mail, Precisava de tudo sobre folhas de carga manuais Obrigado Rui |

Get yourself on a Mass & Balance course, it's the only way to learn the ins and outs of manual load-sheets. This from a guy who used to teach M&B professionally for a number of years. As a previous poster said, picking up bits of information on a message board will leave rather large holes in your knowledge. Furthermore, there are a number of different load-sheet lay-outs and philosophies, and while they all effectively do the same thing, there are different ways you get to the end result depending on the lay-out and philosophy of any given load-sheet, i.e. is the trimming done by whizz-wheel, drop-down box, christmas tree or index numbers? As for weights and indicies, that's relatively simple - but won't teach you how to do a load-sheet: Furthermore, the terms used differ from airline to airline, just to make things a tad more complicated. But here's a short rundown: DOW - Dry Operating Weight (Same as OEW) = Aircraft + crew and standard items (catering, oil, ships documents, catering etc) DOI - Dry Operating Index = Centre of Gravity at DOW OW - Operating Weight = DOW + Take-off Fuel ZFW - Zero Fuel Weight = DOW + payload LIZFW - Loaded Index ZFW = Centre of Gravity at ZFW, can be translated into a MAC% RAW - Ramp Weight = ZFW + Ramp Fuel TOW - Take-off Weight = RAW - taxi fuel LITOW - Loaded Index TOW = Centre of Gravity at TOW, can be translated into a MAC% LAW - Landing Weight = TOW - trip fuel LILAW - Loaded Index LAW = Centre of Gravity at LAW, can be translated into a MAC% |
Help with loadsheet
Hello if you still need any help with the loadsheet mail at info(at)baggelis.com
and we could arange an meeting in skype and i will try to answer you questions regarding the loadsheet |
WTF?
OTA please tell me you dont work for any airline/ground handler!
And if you do please tell me what it is so I can avoid flying with them! Hope you are just generally interested in the topic and its not your company's idea of "training" to let you fish for info on the internet!! Anyway, get some proper training, there are enough half trained guys in the business!:ugh: |
