Fuel Flow Thread

[snakeboy]

I thought it might be helpfull if everybody posted the fuel flow - Lbs/Hr, of various planes. It certainley would have helped me work out the
reserve fuel.

Here's 2, correct me if I'm wrong.

Beechcraft 1900c 1500 lbs/hr
B 737-400 9500 lbs/hr

Your 737 fuel flow isn't quite right... it's more in the average of 4-6000lbs/hr

[snakeboy]

Great stuff, thanks, already helping us out.. Anymore anyone?
747 400 4-6000lbs/hr

[SWAFO]

Wait... you just said 747 in your post... I gave an approximate average fuel flow value for the 737

[snakeboy]

sorry my typo mistake.
737-400 4-6000lbs/hr

[SWAFO]

Ok, just making sure.

[snakeboy]

Anyone know the average fuel flow lbs/hr for Airbus A330-200

Beech Bonanza gets down to around 71Lbs an hour during a ^2 hour flight

Good idea that topic.
But I think that the most helpful data are :
- the cumulated fuel comsumption for the climb and the descent
- the hourly fuel comsumption during the cruise (FL precised)
The first data is quite absolute, it does no depend on the distance
The second data permits also to obtain the reserve (3/4 of hourly consumption for 45 mn reserve).
As my database is corrupted (48 to 52 flights unaccessible : error data on flight ID), I have only manual data for the Embraer 120 and 145 ; those
data are very precise.
- Embraer 120 (a turboprop, needs C4 rank)
The climb and descent consumption is : 800 lbs
The hourly cruise consumption is : 1,200 lbs (at FL300)
The reserve must be : 900 lbs
So for a 2 hours cruise flight (do not forget to exclude the climb and descent time), you need at least 4,100 lbs of fuel
- Embraer 145 (the first choice of Jet, needs C6 rank)
The climb and descent consumption is : 2,450 lbs
The hourly cruise consumption is : 2,530 lbs (at FL340)
The reserve must be : 1,900 lbs
Dan proposed to add another 45 mn reserve to be well protected; you can or cannot do it, it depends on the risk-level that you accept...
One trick to avoid bad surprises : when you plan your flight, plan to land on the opposite runway, i.e if you arrive from the west select an Eastern
runway to be sure to have enough fuel in any case. And if you land on the western runway, do a holding pattern to avoid an early landing.

Three up to now.......

737-400 4-6000lbs/hr

Beech Bonanza gets down to around 71Lbs an hour during a ^2 hour flight

Embraer 120 the hourly cruise consumption is : 2,530 lbs (at FL340)
The reserve must be : 1,900 lbs

I'd be a little more careful with your EMB 120 - according to Embraer, the ceiling is FL320...

Level-D 767-300 10500 lbs/hr. @ FL340 and Mach .81
Climb 7900 lbs. @ 310 kts/M0.79
Descent 4300 lbs. @ 290 kts

Maybe GibbsMusic can add it to his list of aircraft prices:


This is the average of my last six flights:

B1900
Climb to FL250 - 360lbs/hr
Cruise - 774lbs/hr (IAS 160 knots - 60 - 70% throttle. Will average 240knts GS which is what MS9 calculates for flight planning)
Descent - 340lbs/hr
