If the airplane's CENTER OF GRAVITY is at the AFT limit, what flight characteristic should the pilot expect?

Choices

  • ✓ Higher cruise speed and lower stall speed.correct

    reduced longitudinal stability and lighter elevator forces. Aft CG: less tail-down force required → less induced drag → higher cruise speed; lower stall speed (less wing loading needed). BUT: reduced longitudinal stability (closer to neutral point), lighter elevator forces (less pull required for given AoA change), and harder stall recovery. Aft-of-limit CG can be uncontrollable. Forward CG = opposite (more stability, slower, higher stall speed).

  • Lower cruise speed and higher stall speed.

    Reversed — aft CG gives lower stall speed and higher cruise speed.

  • Increased longitudinal stability.

    Aft CG REDUCES stability.

  • No effect on flight characteristics.

    CG significantly affects flight characteristics.

Why

reduced longitudinal stability and lighter elevator forces. Aft CG: less tail-down force required → less induced drag → higher cruise speed; lower stall speed (less wing loading needed). BUT: reduced longitudinal stability (closer to neutral point), lighter elevator forces (less pull required for given AoA change), and harder stall recovery. Aft-of-limit CG can be uncontrollable. Forward CG = opposite (more stability, slower, higher stall speed).
