Fuel flow per engine?

22 September 2014 - 12:47 PM

Is the listed fuel flow when you look at an aircraft per engine or aircraft total?  I would expect aircraft total but it is listed under "engine information" so unsure.

 

e.g. 747-400 with RB211-524G fuel flow = 71,920.  But is the aircraft 71,920 or 4 x 71,920?

 

Also there are no units, is it mass burnt / distance (e.g. kg/km or lb/mile) or mass burnt / time (in which case you need to take account of speed to work out fuel burnt during a trip)?
