If an airplane is loaded in such a way that it is extremely nose heavy, higher than normal forces will need to be exerted at the tail to keep the airplane in level flight. Unfortunately, the scale is now absorbing the weight of the jack in addition to the weight of the airplane.
The datum is determined by the manufacturer, and inthe reference datum is often located along the firewall or at the leading edge of the wing.
The aircraft CG often changes when fuel is used from one of multiple tanks. For instance, browser extensions make it possible to keep all the tools you need a click away. 0 7903 3585 1100 307 1 x 11. One compares the total weight to the total moment and one compares the total weight to the arm of the center of gravity. An even simpler way is to take the METO Hp divided by 2, which is 100 pounds. Newton was able to express the relationship in a single Weight is a force, and a force is a having both a magnitude and a direction associated with it.

The center of gravity can be thought of as where all of the aircraft's mass is concentrated, or the "heaviest" part of the airplane. The higher than normal forces at the tail will create additional drag, which will require additional engine power and therefore additional fuel flow in order to maintain airspeed. Many times older aircraft are bought and sold with incomplete records. 103 1039 896 Medium Small 7,000 Medium Small 4,800 4.
If the fuel tank is located behind the forward CG limit, it cannot be left empty because the aircraft cannot fly without fuel. Figure 4 shows a lever with the pivot point called a fulcrum located at the CG for the lever.
An aircraft has certain fixed points, fore and aft, beyond which the CG should not be permitted at any time during flight.
The Boeing 777 is in service with two engines each having a thrust of around 95,000 lb f, and new aircraft variants are being built with engines of around 115,000 lb f thrust.
