R (2) Do a check of the steering angle on the MCDU.
R (a) On the MCDU, get the STEERING DATA for the BSCU SYS 1 and BSCU
R SYS 2:
R (Ref. Fig. 202/TASK 32-51-00-991-005)
R - On the MCDU, get the SYSTEM REPORT/TEST/L/G page (Ref. AMM TASK
R 31-32-00-860-009).
R - On the SYSTEM REPORT/TEST/L/G page, push the line key adjacent
R to the BSCU1 indication.
R - Make sure that the N/WS handwheels and the rudder pedals are in
R the neutral position.
R - On the BSCU SYS 1 page, push the line key adjacent to the
R STEERING DATA indication.
R - Push the line key adjacent to the REFRESH indication.
R - Print the STEERING DATA page of the BSCU SYS 1.
R - Push the line key adjacent to the RETURN indication to get the
R SYSTEM REPORT/ TEST/L/G page.
R - On the SYSTEM REPORT/TEST/L/G page, push the line key adjacent
R to BSCU2 indication.
R - On the BSCU SYS 2 page, push the line key adjacent to STEERING
R DATA indication.
R - Push the line key adjacent to the REFRESH indication.
R - Print the STEERING DATA page of the BSCU SYS 2.
R - Put the line key adjacent to the RETURN indication to get the
R SYSTEM REPORT/TEST/L/G page.
R (b) Do a check of CAPT,FO, rudder pedal, steering command angle and
R BSCU RVDT input : CAPT ANGLE, FO ANGLE,Pedal angle,STEER ORDER
R and NWS ANGLE 3GC parameters :
R 1 Make sure that the CAPT ANGLE value is less than or equal to 0_
R deg. plus or minus 0.4 deg. for the SYS 1 and SYS 2.
R 2 Make sure that the FO ANGLE value is less than or equal to 0_
R deg. plus or minus 0.4 deg. for the SYS 1 and SYS 2.
R 3 Make sure that the pedal angle value is less than or equal to_
R 0 deg. Plus or minus 0.1 deg. For the SYS 1 and SYS 2.
R 4 Make sure that the STEERING ORDER value is 0 degree for the_
R SYS 1 and SYS 2.
R 5 Make sure that the difference between the NWS ANGLE 3GC SYS 1_
R (value A) and NWS ANGLE 3GC SYS2 (value B) is less than or
R equal to 0.8 degrees.
R (c) If any of the above parameters is out of tolerances, do the
R applicable steps:
R 1 If the CAPT ANGLE value is more than 0 deg. plus or minus 0.4_
R deg. for the SYS 1 and/or SYS 2:

201-220, 301-399, Aug 01/05 CES
R - Replace the XMTR UNIT-N/W STRG HANDWHEEL,CAPT (1GC) (Ref.
R AMM TASK 32-51-11-000-001) and (Ref. AMM TASK 32-51-11-400-
R 001).
R - Do the steps (a) and (b) 1_ again and make sure that the
R CAPT ANGLE value is correct for the SYS 1 and SYS 2, if not
R do step 6_.
R 2_ If the FO ANGLE value is more than 0 deg. plus or minus 0.4
R deg. For the SYS 1 and/or SYS 2:
R - Replace the XMTR UNIT-N/W STRG HANDWHEEL,F/O (2GC) (Ref. AMM
R TASK 32-51-11-000-001) and (Ref. AMM TASK 32-51-11-400-001).
R - Do the steps (a) and (b) 2_ again and make sure that the FO
R ANGLE value is correct for the SYS 1 and SYS 2, if not do
R step 6_.
R 3_ If the pedal angle value is more than 0 deg. plus or minus 0.1
R deg. for the BSCU SYS 1 and/or the BSCU SYS 2:
R - Open the circuit breakers 15CE2 and 16CE2 (the ELAC2 is
R isolated).
R - On the SYSTEM REPORT/TEST/L/G page, push the line key
R adjacent to the BSCU1 indication.
R - On the BSCU SYS 1 page, push the line key adjacent to the
R STEERING DATA indication.
R - On the STEERING DATA page of the BSCU SYS 1, push the line
R key adjacent to the REFRESH indication.
R - Record the value of the pedal angle value (value A1).
