Warnings, hierarchy and ECAM
RetiredF4,
The warnings and their hierarchy are not so different from yours in principle. On current Airbuses, there is no WLDP (warning-lights display panel), but the system PBs (push-button switches) have an amber "FAULT" W/L built-in. (If a PB's normal position is on, it will show a white "OFF" warning when off. The handful that are normally in the off position, like wing anti-ice, have a blue "ON" light.
There are 3 levels of warnings and, below them, advisories.
Level 3 gives a Master W/L (red) to each pilot plus CRC (continuous repetitive chime).
Level 2 gives a Master-Caution W/L (amber) to each pilot plus SC (single chime).
Level 1 gives only a local (PB) amber FAULT light.
ADV (advisory) triggers the relevant system page on an ECAM display, highlighting a system parameter that needs monitoring in flashing green.
Master and Master-Caution W/Ls are cancelled (and hence re-armed) after agreement between the pilots, prior to any drill. This action also stops and re-arms the chimes.
On the upper ECAM DU (display unit), level 3 faults are written in red; levels 2 and 1 in amber; advisories in green. The lower DU shows the system schematic, when necessary. ECAM provides the drills and recognises the completion of each step. There is a recall button if you are uncertain that something was properly actioned. Some of the drills are inevitably long-winded, and must be cross-monitored...
The first Airbuses without flight-engineers, the A310 and A300-600, pioneered ECAM but retained a WLDP. With the next generation, the A320, this was deleted.
Hope this helps, and that any errors will be corrected by others.
