前几天某公司有一架737飞机起飞后起落架收不上去检查后发现是驾驶舱的人工超控手柄盖板未盖好我看书上说应急放下系统是和正常收放系统独立的怎么会有影响呢

接近盖板上有位置电门
When you open the access door to the manual extension control
mechanism, an access door position switch sends a signal to
the manual extend solenoid valve in the landing gear selector
valve. This moves the bypass valve in the landing gear selector
valve to connect all the hydraulic components in the normal
landing gear extension and retraction system to the hydraulic
system return.
