Why should we keep weight and balance record in aviation?
The weight of an aircraft and its balance are extremely important for operating in a safe and efficient manner. When a manufacturer designs an aircraft and the Federal Aviation Administration (FAA) certifies it, the specifications identify the aircraft’s maximum weight and the limits within which it must balance.
Why is weight and balance important?
Weight and Balance Form Proper distribution of weight plays a large and important role in an aircraft’s overall performance. Load your airplane improperly, and it will affect its fuel consumption, speed, rate of climb, controllability, ceiling, and even structural integrity.
What aft adverse loaded CG check is and its importance to weight and balance of an aircraft?
Example Forward and Aft Adverse-Loaded CG Checks On the forward check, any useful load item located in front of 89″ is loaded, and anything behind that location is left empty. On the aft check, maximum weight is added behind 99″ and minimum weight in front of that location.
Why is it important to study aircraft weight balance?
Weight and balance have a direct effect on the stability and performance of the aircraft. If a plane is too heavy, it may never get off the ground. If it’s out of balance, it may be uncontrollable when it does take flight.
Does weight affect balance?
showed that a decrease in body weight leads to improved balance control; these authors showed that approximately 50% of the variance during normal bipedal quiet stance is predicted by body weight. Overall, this suggests that weight is an important factor to explain variations in balance control.
How much weight do you put on a CG?
The two choices ranged in weight from 155 grams to 118 grams. Given that motors have the greatest amount of leverage on the center of gravity this difference in weight is huge. So the fact is you have a range of weights and an issue of where to put that weight to correctly maintain the CG.
Do you need a weight and balance chart?
So the fact is you have a range of weights and an issue of where to put that weight to correctly maintain the CG. Full scale aircraft are typically designed with a weight and balance chart.
How does the weight of the airplane affect the CG?
Placement of baggage and cargo items determines the CG location. The assignment of seats to passengers can also be used as a means of obtaining a favorable balance. If the airplane is tail-heavy, it is only logical to place heavy passengers in forward seats. Also, fuel burn can affect the CG based on the location of the fuel tanks.
What’s the difference between a CG and an AUW?
As an example, the difference in the weight of your servos, electronic gear, motor, and if it is an electric, the battery, can create a large difference in the AUW as prescribed by the manufacturer. This difference makes getting the CG difficult. Recently, I was experimenting with electric motors for a 3D plane.
