单选题
IF BOTH ECAM DISPLAY UNITS FAIL:
A
The E/W Displays are no longer available.
B
The E/W Display can still be presented on the ND Display when switched, using the "ECAM/NDTRANSFER" switch.
C
Only the SYSTEM Display can be presented on the ND Display, when the "ECAM/ND TRANSFER"switch is used.
答案解析
正确答案:B
解析:
题目描述了当ECAM显示单元都发生故障时的情况。选项B正确,因为它指出在使用"ECAM/ND TRANSFER"开关切换时,E/W显示仍然可以在ND显示上呈现。这个开关的作用是将ECAM信息传输到ND上,以便在ECAM显示单元故障时仍然能够获取必要的信息。
