起飞后前缘巡航释压活门是打开位还是关闭位？

作用：防止在巡航时前缘襟翼和缝翼放下
感觉为了不提供压力不应该释压打开吗，书上貌似是关闭位

应该是打开吧。手册好好看看，我手上现在没用NG手册。看不了，要不给我个账号我也学习下？

个人觉得应该是关闭的

The LE cruise depressurization valve is normally open. This permits
hydraulic system B pressure to the LE flap and slat control valve. The LE
flap and slat control valve sends this pressure to the extend lines of the LE
flap and slat actuators.
The FSEU controls the solenoid operated valve in the LE cruise
depressurization valve.
When the FSEU sends a signal to energize the solenoid valve operated
valve, it moves and sends pressure to move the pressure-operated valve.
This stops the hydraulic system B pressure to the LE flap and slat control
valve. This prevents extend pressure to the LE flap and slat actuators.
