What does 'flaps greater than 0' signify in relation to HYD 1B and HYD 2B?

The phrase 'flaps greater than 0' signifies that the flap system has been deployed to a degree, which is a crucial indicator of how the hydraulic systems are functioning. When the flaps are extended, it typically means that the hydraulic systems responsible for operating them—such as HYD 1B and HYD 2B—are activated to adjust the wing shape for increased lift and drag during certain phases of flight, particularly during takeoff and landing.

When the flaps are set to a value greater than 0, it requires hydraulic pressure to maintain their position, indicating that the hydraulic systems are actively in use. This activation is essential for the aircraft to perform efficiently during critical flight operations, such as slowing down for landing. Therefore, this choice correctly describes the relationship between flap deployment and the activation of hydraulic systems.

The other options do not directly relate to the specific meaning of 'flaps greater than 0' in terms of the operation of hydraulic systems. For example, while the act of landing does involve flap deployment, it is not the direct interpretation of the statement about hydraulic activation. Similarly, cruising and malfunction scenarios do not imply a direct relationship with the state of the flaps and the corresponding hydraulic systems.
