5.3 System Status Page (MFD―Normal Mode)
The AUX – SYSTEM STATUS page on the MFD displays LRU health status when the system is in
normal mode.
Failed Path Messages
A 'FAILED PATH' message indicates that a data path connected to the GDU (PFD or MFD) or the
GIA 63W (1 or 2) has failed. This 'FAILED PATH' message is triggered by a timeout of any digital
channel. The channels that are checked are displayed on the following pages in configuration
mode:
1. GDU RS‐232 / ARINC 429 CONFIG (PFD 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 the message would remain through
the end of the flight during intermittent failures (to alert the maintenance crew). This also
keeps the crew from having to repeatedly acknowledge messages in the case of intermittent
failures.
