Center of gravity (CG). The point at which an airplane would balance if it were possible to suspend it at that point.
Center of gravity is calculated as follows:
Determine the weights and arms of all mass within the aircraft.
Multiply weights by arms for all mass to calculate moments.
Add the moments of all mass together.
Center of Gravity Limits
Very important: these are the forward and aft limits in which the 'C of G' must fall if the aircraft is to be operated safely and in stable controlled flight.
gravity - The natural force that pulls an object toward the earth. We experience gravity as weight. An airplane must generate enough lift to counteract the weight of an aircraft .
Gravity. The force exerted on a body by the mass of the earth. It is equal to the "weight" of the body in pounds.
Microgravity
The condition of near weightlessness induced by free-fall or unpowered space flight.
High Gravity
HIT(S)
1. (A/A) Momentary radar return(s) in search. (Indicates approximate altitude information from fighter.) 2. (A/G) Weapons impact within lethal distance.
Centre of Gravity
chaff
Radar-reflective particulate matter sized to match known or suspected wavelengths being used by the enemy, and released by an aircraft to confuse detection systems.
Centre of Gravity The point in the aircraft through which the sum of the weights of the parts which make up the aircraft may be assumed to pass whatever the attitude of the aircraft.
CENTER OF GRAVITY - (CQ), the point on an aircraft's structure where the total combined weight forces act.
CENTER-SECTION - The central panel, or section, of an aircraft's wing.
There is no gravity.
The earth sucks.

This chapter pulls together some basic physics ideas that are used in several places in the book.
Center of Gravity (CG) - The longitudinal and lateral point in an aircraft where it is stable; the static balance point.

The weight of the airplane, pilot and passengers, fuel and baggage is distributed throughout the aircraft, as shown by the small downward arrows in the diagram.

Cold Shock: The loss of body functions, or death, immediately on sudden immersion in very cold water. See also Hypothermia and Vasogenic Shock.
Controlled Airspace: Airspace closed to unauthorised aircraft (and see TPA).

Lift opposes gravity.
Thrust opposes drag.
Drag and weight are forces inherent in anything lifted from the earth and moved through the air.
CG Center of Gravity. A measurement used when balancing blades, as well as the model overall. Describes a central point in a given body, where all weight is considered to be concentrated. A central balance point.

Chaff or Window: Metal foil strips dropped for aircraft to disrupt and confuse radar detection.
Chandelle: Reversal of course by a sharp climbing turn.
Forget all that stuff about thrust and drag, lift and gravity; an airplane flies because of money. It's better to be down here wishing you were up there, than up there wishing you were down here.
Center of Gravity.-The point of balance of an airplane which may be otherwise defined as the point through which the mass of an airplane acts. If the weight is too far forward the machine is nose-heavy.
A big advantage is Kevlar's specific gravity of 1.5 in relation to E-glass with about 2.
The center of gravity is shown as a red dot and the center of pressure as a green dot. The tail of the kite is given as a green line at the bottom.
Side shows the kite as viewed looking along the surface.

The adjustment required will depend on the helicopter make/model as well as the particular helicopter and it's center of gravity.

g - The force of gravity, e.g. 9g = 9 x the force of gravity, about the limit of human endurance

This was not helped by a design defect where the center of gravity shifted rearwards once two-thirds of the fuel had been used. This had the effect of making the plane uncontrollable, resulting in an endurance of only 45 minutes in clean condition.
At first he concluded there must be expansion of wings large enough to resist in a sufficient degree the specific gravity of whatever is attached to them, ...
ELTs that activate automatically use a 'G-Switch' (gravity switch) that triggers the ELT when it senses that a crash has occurred. ELT makes it easier for rescue teams to get the exact location of a downed aircraft.
For a given centre of gravity, there is a LD angle that results in a certain
trimmed flight speed and pitch attitude.
If the LD angle is increased the plane will take on a more nose up pitch attitude, ...
g - the acceleration force of gravity, normally 1g on earth. Zero g (0g) is weightlessness, as experienced by orbiting astronauts. g is expressed as positive (+) and negative (-) values.
7-inch center of gravity (CG) range at maximum gross weight (increasing to 10 inches at 1,950 pounds gross weight and lower) offers good loading flexibility.
From the above we can conclude that there is a forward limit of the position of the center of gravity, forward of which there is a controllability problem for a given aircraft.
The point of attachment is the aircraft's center of gravity or balance point. Most jet aircraft have swept wings, meaning the wings are angled back toward the rear of the plane.
Balance refers to the location of the centre of gravity (cg) along the longitudinal axis of the aircraft. The cg is the point about which an aircraft would balance if it were possible to suspend it from that point.
The primary advantage of this configuration is the ability to lift heavy loads whose position relative to the helicopter's centre of gravity is less critical than in the single rotor configuration.
To convert value to weight, you need to know the specific gravity (SG) of the fluid. AVGAS has a specific gravity of 0.71 (one litre weights 0.71kg).

Locate the airplane's center of gravity and use the onboard battery pack to help obtain the correct balance. Mount the battery pack securely using rubber bands or hook and loop fasteners.

ROTATE In flight, any aircraft will rotate about its centre of gravity, a point which is the average location of the mass of the aircraft.
The mighty forces of gravity just look up at you and nod, as if saying, "You go girl." Now that's flying! That was more than 20 years ago. (Did I say 20, no I mean 15. wait if I'm only 32 then it must have been just 10, yeah that's it.10 years ago.

PRE-PLANNED LOADS. Loads set up as to weight, cube, manifested, balanced for center of gravity (CG), and ready to load upon arrival of aircraft (synonymous with "Type loads").
This correction is required because precession causes a nose down tendency and because the tilted disk produces less vertical lift to counteract gravity.
Airplanes fly when the movement of air across their wings creates an upward force on the wings (and thus the rest of the plane) that is greater than the force of gravity pulling the plane toward the earth.
The Wrights developed a far more sophisticated technique, in which the center of gravity remained constant and equilibrium was controlled by adjusting the angles of the wings and other airfoils, thus varying the air pressure against them.
In 1804 Cayley constructed a a model monoplane glider that was five feet (1.524 m) long. The model featured an adjustable cruciform tail, a kite-shaped wing mounted at a high angle of incidence and a moveable weight to alter the center of gravity.
