    Study Notes

    Center of Gravity

    • The Center of Gravity is a dynamic force that changes with cargo load, fuel burn, and passenger movement.
    • It's critical to understand the basic physics of the Center of Gravity to maintain an aircraft's balance throughout flight.

    Aircraft Stability

    • Aircraft stability refers to the inherent ability of an aircraft to return to its original flight condition after being disturbed by an external force, such as turbulence.
    • There are two types of stability: static and dynamic.
    • Static stability is the aircraft's initial tendency to return to its original position, while dynamic stability is the aircraft's tendency over time after the initial disturbance.

    Center of Gravity and Stability

    • The position of the Center of Gravity affects an aircraft's stability and control.
    • A forward Center of Gravity close to the nose may result in a more stable but less maneuverable plane, requiring greater control force to pitch up.
    • A rearward Center of Gravity near the tail makes the plane less stable but more responsive to control inputs, which could lead to over-controlling.

    Center of Gravity and Control

    • The Center of Gravity plays a critical role in aircraft control, particularly pitch control.
    • The further the Center of Gravity is from the center of lift, the more leverage (moment arm) is available to the control surfaces, such as elevators, to pitch the aircraft up or down.
    • A well-placed Center of Gravity ensures that the aircraft is controllable across its flight envelope and that the control surfaces have the appropriate effectiveness.

    Center of Gravity and Trim

    • The position of the Center of Gravity affects the aircraft's trim requirements.
    • An aircraft with its Center of Gravity located at or near the center of the lift will require less trim, resulting in reduced drag and improved fuel efficiency.

    Real-World Examples

    • Improper weight and balance checks can lead to a shift in the Center of Gravity, resulting in a loss of pitch control and potentially catastrophic accidents.
    • Different types of aircraft have unique optimal Center of Gravity ranges, with general aviation planes having a broader tolerance and commercial airliners operating within stricter bounds.

    Managing the Center of Gravity

    • Pilots manage the Center of Gravity with careful loading and fuel consumption planning.
    • Calibrated management during flight is key to maintaining an optimal Center of Gravity.
    • Regulations ensure that every aircraft's Center of Gravity is within safe limits, guided by manuals, charts, and regulations.

    Calculating the Center of Gravity

    • Calculating an aircraft's Center of Gravity involves understanding each element's weight and arm.
    • The arm is the distance from a reference point, usually the nose of the aircraft.
    • The Center of Gravity can be determined by multiplying each element's weight by the arm and summing these up.
