Troubleshooting Recommendations:
- Switch to Hydraulic synoptic page and check for any abnormal indications, magenta dashes for the hydraulic indication pages.
- Hydraulic pressure data is supplied to the SECU on the R-GP-5 bus, if the hydraulic information is good on the displays, troubleshoot the R-GP-5 ARINC databus.
- Additional troubleshooting on this condition, refer to AW300-29-0079.
