Fuel flow during taxi
Hi everyone
I'm currently working on fuel burn model, which assesses fuel burn on all phases of flight, including taxi in and taxi out, taking taxi time, holding time into account. The problem is, that I can calculate fuel flow only for IDLE thrust conditions. I'm assuming, that the fuel flow during taxi is little bit higher, but can't find any information about this on the internet. So if anyone of you could write me some "real world" values I'd really appreciate that. The type of aircraft can be B737, A320 or any jet currently used by airlines. The values can be fuel flow in different units, fuel burn etc. Everythink will help me.
Thank you very much in advance.

Most modern jets like the ones you mention don't need or use more than idle thrust to taxi, although some have 'ground idle' and 'flight idle' modes.
For B737 and A320 I'd say use about 10kg/min. (assuming two engines running - my airline shuts one down for taxi in as a standard procedure, and I believe some larger jets will only start up nos. 3 and or 4 once taxiing out. I have no experience of those aircraft.)
