OK, so I had a look in the FCOM (see link in my earlier post). Disclaimer - I’m a rank amateur at this and definitely not a real A320 pilot lol.
It looks like you had a failure in both fuel pumps from the left tank, and this message comes up when the centre tank is empty (which I think means that fuel is supposed to be coming from the left and right tanks, but the left tank is working with gravity feed only - ie no pumps). Hence why it says in white - when left tank fuel is required… - then in blue - left tank feed is gravity only.
This places restrictions on avoiding negative G factor etc. Here is the procedure from the FCOM:
[note that there is a different procedure if the cenntre tank is not empty]
This procedure also requires the GRVTY FUEL FEED procedure to be run depending on the exact circumstances. Here is that procedure:
The other warning “FWS FWC 1 FAULT” I think means that one of the flight warning computers has a fault. I found this page in the Supplementary Procedures:
It basically says to cycle the circuit breaker of the affected FWC. If both fail, there seems to be reference to monitoring all the flight instruments etc.
The FCOM here is your friend!
