Standing on ground, what is the idle fuel flow of an A320? ISA conditions, both engines running?


1 Answer 1


I don’t normally post answers that I cannot personally verify, but I have a Facebook friend who is FO in an A320. I sent him a message and asked your question. I don’t have any official documentation to reference, so take this as anecdotal...

An A320 with CFM engines burns about 600lb/hr per engine at idle in ISA conditions.

An A320 with V2500 engines burns about 730lb/hr per engine at idle in ISA conditions.

If the APU is running, it will burn another 300lb/hr.
