What formula is used to determine the moment of an aircraft?

To determine the moment of an aircraft, the correct formula is Moment = weight x arm (or distance from the reference point). In this context, "weight" refers to the force acting downwards due to gravity, which is typically represented in pounds or newtons. The "arm" is the horizontal distance from the center of gravity or the reference point to the point where the weight is applied.

Using multiplication, as stated in the formula, shows how the effect of the weight on the aircraft's stability and balance is assessed. The greater the distance (arm) from the reference point, the larger the moment will be for the same weight, which can significantly impact the aircraft's performance and handling characteristics.

This understanding is vital for pilots as it helps them manage weight distribution within the aircraft effectively to ensure balanced flight and compliance with safety regulations.
