What is the ground idle fuel flow of an A320 (CFM or IAE or neo)? Standing on ground, what is the idle fuel flow of an A320? ISA conditions, both engines running?
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.
