805.  Align Fault - Fault Isolation
805. 对准故障 - 故障隔离

 
 

A.   Description 描述

 
 

(1)  This task is for this maintenance message:
(1) 此任务是为了这个维护消息:

 
 

(a)  34-21004 ALIGN FAULT
(a) 34-21004 对准故障

 
 

(2)  The maintenance message is identical for the left and right ADIRS. The left ADIRS maintenance message is shown on the ADIRS L BITE page on the CDU. The right ADIRS maintenance message is shown on the ADIRS R BITE page on the CDU.
(2) 左右 ADIRS 的维护信息相同。左 ADIRS 的维护信息显示在 CDU 上的 ADIRS L BITE 页面上。右 ADIRS 的维护信息显示在 CDU 上的 ADIRS R BITE 页面上。

 
 

(3)  The ADIRU keeps a record of its last position. You must enter the present position data during the alignment mode. The ADIRU will not go into NAV mode if present position has not been entered by the end of the alignment period. The ADIRU will continue to prompt for a present position and the ALIGN FAULT will not clear.
(3) ADIRU 会记录其上次位置。在校准模式期间,您必须输入当前位置数据。如果在校准期结束时未输入当前位置数据,ADIRU 将不会进入导航模式。ADIRU 将继续提示输入当前位置,ALIGN FAULT 不会清除。

 
 

(4)  This message shows when you enter position data that is more than 1 degree different than the recorded latitude or 1 degree different than the recorded longitude. This message will also show when the ADIRU’s post alignment computed latitude is different than the manually entered latitude.
(4) 当您输入的位置数据与记录的纬度相差超过 1 度或经度相差超过 1 度时,将显示此信息。当 ADIRU 校准后计算的纬度与手动输入的纬度不同时,也会显示此信息。

 
 

(5)  This condition causes the ALIGN light on the MSU to flash, the status code 04 to show on the ISDU and ENTER IRS POSITION message to show on the CDU.
(5) 这种情况会导致 MSU 上的 ALIGN 指示灯闪烁,ISDU 显示状态代码 04,CDU 显示 ENTER IRS POSITION 消息。

 
 

B.   Possible Cause
B. 可能原因

 
 

(1)  The entered present position is more than ±1 degree different than the present position stored in memory.
(1) 输入的当前位置与存储在内存中的当前位置相差超过±1 度。

 
 

NOTE:  This can occur when an ADIRU is replaced (if the ADIRU was turned off at a different location) or the airplane is moved after the ADIRU powered down. It can also occur if ADIRU power is removed before the ADIRU had time to complete a full power down sequence when it stores the last known valid position.
注意:当更换 ADIRU 时(如果 ADIRU 在不同位置关闭)或者在 ADIRU 关机后飞机移动时可能会发生这种情况。如果在 ADIRU 完成完整关机序列之前就移除 ADIRU 电源,也可能会发生这种情况,此时 ADIRU 会存储最后已知的有效位置。

 
 

NOTE:  If this condition occurs, the ALIGN light on the Mode Select Unit (MSU) will flash. Confirm the location of the airplane and enter the present position again to align the ADIRU.
注意:如果出现这种情况,模式选择单元(MSU)上的 ALIGN 指示灯会闪烁。确认飞机位置并重新输入当前位置以对齐 ADIRU。

 
 

NOTE:  You might need to enter the data three times.
注意:您可能需要输入数据三次。

 
 

(2)  The entered latitude fails the ADIRU’s post alignment performance test.
输入的纬度未通过 ADIRU 的后校准性能测试。

 
 

NOTE:  If this condition occurs, the ALIGN light on the MSU will flash and the ADIRU will again request a manual entry of position. If the same position that was entered initially is entered again, the ADIRU will fail the post alignment performance test and fault itself. Make sure that the position entered initially was accurate before entering it again. If it was not accurate then enter the accurate position. If the new position entry passes the ADIRU’s post alignment comparison test, the ADIRU will complete the alignment and be ready for NAV mode.
注意:如果出现此情况,MSU 上的 ALIGN 指示灯将闪烁,ADIRU 将再次请求手动输入位置。如果再次输入最初输入的相同位置,则 ADIRU 将无法通过后校准性能测试并自行故障。确保最初输入的位置准确无误,然后再次输入。如果最初输入的位置不准确,则输入准确的位置。如果新的位置输入通过 ADIRU 的后校准比较测试,ADIRU 将完成校准并准备好进入导航模式。
