5.3 System Status Page (MFD Normal Mode)
The AUX – SYSTEM STATUS page on the MFD displays LRU health status in normal mode.
Failed Path Messages
The following message indicates that a data path connected to the GDU (PFD1 or MFD) or the
GIA 63/W (1 or 2) has failed.
•
FAILED PATH – A data path has failed.
The FAILED PATH message is triggered by a timeout of any one digital channel. The channels
that are checked are listed on these pages in config mode:
1) GDU RS-232 / ARINC 429 CONFIG (PFD1 and MFD)
2) GIA RS-232 / ARINC 429 CONFIG (GIA1 and GIA2)
3) GIA CAN / RS-485 CONFIGURATION (GIA1 and GIA2)
Once the FAILED PATH message has been triggered, it remains on the list of messages until
the next power cycle. This latching was implemented so that for intermittent failures, the
message would remain at the end of the flight (to alert the maintenance crew). This also keeps
the crew from having to repeatedly acknowledge messages in the case of intermittent failures.
The box next to each channel indicates the current status of the channel as indicated below:
•
Red = data path is known to be failed
•
Black = data path status is unknown
•
Green = data path is known to be good
The applicable data paths can be verified by viewing the configuration mode pages listed below.
