Load Plan

Wed Mar 13, 2002 1:41 am

Hello everybody!

What items usually take part to the compilation of the load plan on an airliner?

A clear explanation or an example will be appreciated.

Thanks in advance.

The airplane cabin is broken down into sections (ie. A,B,C) and the passengers are seated accordingly to keep the weight and balance ok. Standard passenger weights are used depending on summer or winter. So it would look something like 32M and 29F in A, 75M and 62F in B, etc. Bags and freight are weighed and placed in cans and the cans are loaded according to the load detail.
Let me know if you want more detail.

When we load a plane with cans and cargo, we're given a load sheet (plan) prepared by the dispatchers who also configure weights and measure of an aircraft.

Most of the time, it has seemed to me that the heaviest things go in the front of the plane, which is why pallets are ahead of the cans.

One time we loaded an oil filter for a ship on the front hold of a 763 and this thing was HEAVY! I'll bet it was at least 15,000 pounds. It was loaded in the front of the aircraft.

Boy I wish I had one of the old Reeve 727 or Electra Load sheets to scan and show you. I used to have to fill them out every day.

Basicly it all has allready been explained. The aircraft is divided into sections and you know how much weight you can put into each section.

You just have to make sure that you put less weight then the max in each secton. As far as load sheets and where loads go, that varies depending on aircraft. For example we tried to put more weight forward on those 727's since they where tail heavy to begin with. The Electras we tried to put the heavier load farther back, nearer to the wing spar and the C or G.

How you decide on where the load goes is really dependent on the aircraft type and the structural limitations, you also have to consider fuel burn as well.

When I'm doing my plans I like to think of a pyramid centered over the wings. That's where the heaviest stuff tends to go because you have the strongest strucuture underneath. Then you work out from there.

For the MD-11F we plan them nose heavy because our MDs have tail tanks which exerts a substantial aft moment, but then it does go away because it's all fuel. For the 747s I do it just the opposite and have them slightly tail heavy because the fuel loaded exerts a forward moment.

The whole point is to get the aircraft as balanced as possible for several reasons but these 2 really come to mind: if the load plan is very balanced if something breaks loose the effect of the movement is minimized. Also, the closer to balance you are you fuel burn seems to be better and the aircraft is easier to control.

Just my two bits.
BTW, if you have any additional questions mail me.

is that a light at the end of the tunnel or just a train?
