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. 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. OTA 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. Fleetwood mac tusk be full album download zip. 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? Anupama medium telugu font free download. 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.

I was looking for an app that I could use to quickly crosscheck the results of Manual Load Sheet / Trim Chart. Normally we don`t do it manually. Murphy`s law. NOTES OF WEIGHT AND BALANCE - 1. Explanation loadsheet. Load control IATA codes. The Loading Instruction Report ( LIR ). Aircraft type A320P ( A320 palletized ). Seating configuration of Y180 where 'Y' denoting economy class. 2/05 is the crew. Load devices ), position, destination, gross weight and content.

AIRCRAFT WEIGHT AND BALANCE BASIC FOR LOAD CONTROL • 1. Be Smarter • INTRODUCTION Compliance with the weight and balance limits of any aircraft is critical to flight safety. Operating above the maximum weight limitation compromises the structural integrity of an aircraft and adversely affects its performance.

 Operation with the center of gravity (CG) outside the approved limits results in control difficulty. • REGULATORY REQUIREMENTS  Training and qualification records  The Load Control process must have an audit trail for each departure.  Weight and balance records must be retained  The operating airline will identify specific loading positions  The operating airline will specify requirements for presenting load information  Weight determination of load and clearance measuring systems must be calibrated and/or checked at intervals determined by the operating carrier or state.
