Boeing 747-400ER Fuel Flow

Posted by Jason Hite on 14 December 2017 - 07:52 PM

Hi,

 

I have noticed that the B744ER fuel flow is about 10k higher than the regular B744. Is this correct? I know that the longest range engine option on the B744ER is the PW4060 which is more fuel hungry than the longest engine option on the B744, which is the RB211, but this major difference makes it virtually impossible to make a profit on long-range routes and whatever profit you can make is very minimal, whereas the B744 can make a reasonable profit on the same routes. Is this correct?


I've gone through all of the engines and corrected any anomalies - thanks for highlighting this.



Now that the fuel flow is only 2-5k more than the 747-400, the profitability is much more reasonable. Still a slight difference, but I'm chalking it down to the PW4062 being more fuel hungry.

Yes, also the engines have a higher thrust provision due to increased MTOW, thus fuel consumption will be higher :)
