A330 ECAM HYD PAGE
 

Hey guys,

does anyone know why the green hydraulic reservoir quantity shows a white line which is replaced by two amber bars below 17l on the ECAM HYD page? There is no further explanation in the FCOM.

Thanks in advance 🙏

Thank you. It is still confusing for me. Why only on the green system. There is also a normal filling range and low level warning treshold.

Review what the green system operates and you may find the answer to your question and why fluid level ,temp and px are considered as optimal . It is the "pre warning " if you like that you just may start to experience some pressing issues ,especially if in flt .
I agree with the question ref the B and Y systems but i guess the designers thought that they where in building another fail safe protection for the "primary" system.
