Under which condition is a forward center of gravity (CG) most critical?

• A. During takeoff
• B. In mid-flight
• C. On landing
• D. During cruise

Answer: (C)

A forward center of gravity (CG) is most critical during landing because it affects the aircraft's stability and control characteristics. When the CG is forward, the aircraft may require higher landing speeds, which can lead to an increased landing distance. Furthermore, a forward CG can reduce the effectiveness of the elevator, making it more difficult for the pilot to manage the descent rate and flare the aircraft appropriately for a safe landing.

In contrast, while other phases of flight, such as takeoff or cruise, can also be influenced by CG positioning, the combined effects of airspeed, flap settings, and landing configuration mean that landing presents unique challenges. The pilots must be aware of the CG's effect on pitch control and the approach to landing, as an excessive forward CG during this phase may affect the ability to perform a proper flare and touchdown.

Understanding the impact of CG on stability and control during landing is critical for ensuring safe operations, making this condition particularly significant compared to takeoff, mid-flight, or cruise phases where the aircraft may still retain more manageable handling characteristics despite a forward CG.
