  • ADM-R TOTAL PRESSURE [19FP2]
  • ADM-STBY TOTAL PRESSURE [19FP3]
  • ADM-R STATIC PRESSURE [19FP4]
  • ADM-L STATIC PRESSURE [19FP5]
  • ADM-R STATIC PRESSURE [19FP6]
  • ADM-L STATIC PRESSURE [19FP7]

3. Fault Confirmation
Subtask 34-13-00-740-361-A
A. Not applicable, you cannot confirm this fault on the ground.
4. Fault Isolation
Subtask 34-13-00-810-260-A
A. If there is a repetitive RETARD aural warning message, do a check of the speed value on CAPT (ADR1) (or ADR3 after SWITCHING AIR DATA on CAPT position) and F/O (ADR2) (or ADR3 after SWITCHING AIR DATA on F/O position) PFDs:
   (1) If a residual speed of 80 kts or more is shown on the speed scale on:
   (2) If no residual speed is shown on CAPT and F/O PFD, replace the ADM-L TOTAL PRESSURE [19FP1] , ADM-R TOTAL PRESSURE [19FP2] , ADM-STBY TOTAL PRESSURE [19FP3] AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
Subtask 34-13-00-810-261-A
B. If the fault continues, replace the ADM-R STATIC PRESSURE [19FP4] AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
   (1) If the fault continues, replace the ADM-L STATIC PRESSURE [19FP5] AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
     (a) If the fault continues, replace the ADM-R STATIC PRESSURE [19FP6] AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
       1 If the fault continues, replace the ADM-L STATIC PRESSURE [19FP7] AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
         a If the fault continues, replace the ADM-STBY STATIC PRESSURE [19FP8] AMM 34-11-17-000-001 and AMM 34-11-17-400-001.
