Final answer:
When green hydraulic pressure is lost, the anti-skid system may become inoperative, potentially leading to wheel lock-up and longer stopping distances. Additionally, the loss of hydraulic pressure can affect the nose wheel steering, making it difficult to maneuver the aircraft on the ground.
Step-by-step explanation:
When green hydraulic pressure is lost, it can affect both the anti-skid system and nose wheel steering in an aircraft's landing gear/brakes panel.
In the case of anti-skid, the system relies on hydraulic pressure to modulate the braking force on the wheels and prevent skidding. When green hydraulic pressure is lost, the anti-skid system may become inoperative, resulting in the potential for wheel lock-up and increased stopping distances during landing or braking.
Regarding nose wheel steering, green hydraulic pressure is used to control the movement of the nose wheel. When the pressure is lost, the nose wheel steering may also become inoperative, making it difficult for the pilot to maneuver the aircraft during taxiing or on the ground.
