A. Do a Check of the Position Pick-Off Units (PPUs) on the Centralized Fault Display System (CFDS)
(1)
Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
(2)
Get access to the SYSTEM REPORT/TEST (F/CTL) page on the Multipurpose Control Display Unit (MCDU) (Ref. TASK 31-32-00-860-006).
(3)
Do a check of the flap PPU angles (deg) at the slat/flap control lever position FULL on the MCDU as follows:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the MCDU: On the MCDU:
-push (in) the line key < SFCC - the MCDU shows the SFCC 1 menu.
1.
2.
Push (in) the NEXT PAGE button. - the MCDU shows the next page of the SFCC 1 menu.
3.
Push (in) the line key SYSTEM - the MCDU shows the SFCC 1 FLAP DATA FLP >. SYSTEM DATA menu.
4.
Push (in) the line key < PPU. - the MCDU shows the PPU DATA page(s): Refer to Table 1.
NOTE : The APPU and the FPPU synchro
____ angles must agree within 1.3 deg. The LH APPU and the RH APPU synchro angles must agree within
0.45 deg.

-------------------------------------------------------------------------------
ACTION RESULT -------------------------------------------------------------------------------
5. Write down the APPU and the FPPU angles (deg) shown on the display or push (in) the line key PRINT > to get a print-out of the screen.
NOTE : These angles, shown at
____
removal, will be used as a
datum. They will let you
compare the APPU and the
FPPU angles after the
installation of the
actuators (Ref. TASK 27-54-49-400-001), (Ref. TASK
27-54-49-400-002), (Ref.
TASK 27-54-49-400-003),
(Ref. TASK 27-54-49-400-004).
6.
Push the line key < RETURN frequently until the CFDS menu page is shown.
7.
De-energize the aircraft electrical circuits (Ref. TASK 24-41-00-862-002).
