737NG  P5后顶板的飞行数据记录OFF灯
我所理解的
如果在地面，在PSEU上模拟空中模式，正常情况下（所有设备都正常无故障）  灯是不是应该是灭的

但是FIM上有一段原文在  FIM31-31  805
(a)  Put the NORMAL/TEST switch in the NORMAL position.

WARNING:  MAKE SURE ALL PERSONS AND EQUIPMENT ARE CLEAR OF ALL CONTROL SURFACES AND LANDING DOOR AREAS. CONTROL SURFACES AND LANDING GEAR DOORS CAN MOVE WHEN YOU DO THE AIR MODE SIMULATION. THIS CAN CAUSE INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT

(b)  Do the air mode simulation with the PSEU BITE. To do the air mode simulation, do this task: Put the Airplane in the Air Mode, AMM TASK 32-09-00-860-801.

(c)  If the OFF light comes on then do the Fault Isolation Procedure - OFF Light On.

(d)  If the OFF does not come on, then do the Fault Isolation Procedure - OFF Light Off.

(e)  Return the airplane to the ground mode with the PSEU BITE. To return the airplane to the ground mode, do this task: Return the Airplane to the Ground Mode, AMM TASK 32-09-00-860-802.

Fault Isolation Procedure - OFF Light Off

(1)  Replace the flight data recorder/mach airspeed warning panel, P5.

These are the tasks:

Flight Recorder/Mach Airspeed Warning Test Module Removal, AMM TASK 31-31-12-000-801,

Flight Recorder/Mach Airspeed Warning Test Module Installation, AMM TASK 31-31-12-400-801.

(a)  Do this task: Flight Data Acquisition Unit (FDAU) BITE Procedure, 31-31 TASK 801.

(b)  If the OFF light on the flight data recorder/mach airspeed warning panel, P5, is off, then you corrected the fault.

请高手解释下
灯本来灭的不是正常情况吗为什么要换面板，而且换完面板后的标准也是灯灭，这不等于没换吗。

“Fault Isolation Procedure - OFF Light Off”
我个人认为，这个程序是OFF LIGHT 始终不亮（比如PSEU在地面模式，NORMAL/TEST 开关在正常位）的隔离程序。

同意楼上的观点。

应该不亮，亮有两种可能，一个是在测试位，一个是故障
