### Aircraft's Weight and Balance

The aircraft’s weight and balance data is important information for a pilot that must be frequently reevaluated. Although the aircraft was weighed during the certification process, this data is not valid indefinitely. Equipment changes or modifications affect the weight and balance data. Too often pilots reduce the aircraft weight and balance into a “rule of “If I have three passengers, I can load only fuel; four passengers, 70 gallons.”

Balance computations should be part of every ng. Never assume three passengers are always instead, do a full computation of all items the aircraft, including baggage, as well as passenger. It is recommended that all bags be a precise computation of how the aircraft of the CG was stressed in the discussion controllability, and performance. Unequal load accidents. A competent pilot understands effects of CG on an aircraft.

Balance are critical components in the utilization its fullest potential. The pilot must know can be loaded onto the aircraft without limits, as well as weight limits to conduct flights with or without a full complement of passengers. For example, an aircraft has four seats gallons of fuel. How many passengers can carry? Can all those seats be occupied at varying fuel loads? Four people who each leads to a different weight and balance four people who each weigh 200 pounds. scenario loads an additional 200 pounds onto the equal to about 30 gallons of fuel.
weight may or may not place the CG outside envelope, but the maximum gross weight could excess weight can overstress the aircraft performance.

Aircraft, such as balloons and weight-shift control, do not require weight and balance computations because the load is suspended below the lifting mechanism. The CG range in these types of aircraft is such that it is difficult to exceed loading limits. For example, the rear seat position and fuel of a weight-shift control aircraft are as close as possible to the hang point with the aircraft in a suspended attitude. Thus, load variations have little effect on the CG. This also holds true for the balloon basket or gondola. While it is difficult to exceed CG limits in these aircraft, pilots should never overload an aircraft because overloading causes structural damage and failures. Weight and balance computations are not required, but pilots should calculate weight and remain within the manufacturer’s established limit.
