Final answer:
When the center of gravity is past the forward limit, it impedes the helicopter's ability to tilt back, leading to a lack of forward control and difficulty in hovering into the wind.
Step-by-step explanation:
If the center of gravity was past the forward limit, it would most likely result in the inability to hover into the wind due to a lack of forward control.
This is because when the center of gravity is too far forward, the helicopter's ability to tilt back is compromised, thus preventing it from countering the effect of wind coming from the front. This challenge is critical for helicopter stability and piloting.
