cruise speed and fuel burn

[EHM-1821 Javier]

Does anyone know the maximum range(C208B), cruise speed(all) and fuel burn(all) of the 3 default boeing aircraft and the C208B in FS2004?

The cruise speed given by the info of the plane when i tried it out, the plane went overspeed at the cruise speed given

I just bought FSpassengers and my "company" has these aircraft.

Thank you
Regards

Hey Javier,

Is this one of those "wind chnges, aircraft overspeeds" things, 'cause the kneeboard data should be correct in all cases for the default aircraft (even if it's not "real world").

Off the top of my head, the 737 cruises between 0.790 and 0.810 (c. FL330) depending on cost index - 0.790 is about right for a CI of 100.

You'd really need an FMC for the Boeing birds, that understands the flight dynamics and load of the particular model, to get useable data. Not tried FreeFMC (or whatever it's called) because I went straight from not flying the 737 to the PMDG...

Hi Murray

Its not the kneeboard i meant although i have not checked it out.its the panel that shows the aircraft performance at the choose aircraft menu.

and i tested the plane in near perfect conditions so i dont think it is the wind causing it.

Ah, that thing. I've always considered that to be "not for navigational use" although it should be pretty close.

See if you can find a Werner Schott checklist (search on AvSim for "Schott") - he's done checklists for all the default planes since FS2000, and his FS2002/2004 checklists are pretty accurate - I use his 737-400 one with my fleet/PM 737-800 and haven't had any really nasty accidents.

I've never been able to reach maximum altitieds in FS... the highest I've ever gone was about 37,000ft. I can't maintain a fast enough airspeed to maintain altitude before stalling, it's very wierd.

And to sidetrack a little, how much is FSPassengers, Javier?

[EHM-1821 Javier]

maybe try to achieve max speed before using slew mode to bring it up lol;D

and thanks murray.does it show fuel burn?

btw,you have FSP?What is your airline called?
just curious;D;D;D

[EHM-1612 Paolo]

I downloaded a concept airplane from surclaro.com and it goes Mach4.30 and I reached with it something like 30480m that are 100000ft. This is the limit altitude, while the speed limit doesn't exists I think.....

[EHM-1821 Javier]

anyone know the fuel burn of the 737-400, 747-400, 777-300 and C208B?

i created my own mini checklist for these aircraft as they all have the Landmark Airlines Livery(on just 1 page:o) and all i need is the fuel burn so that i dont carry too much fuel when i fly with FSP.

Thank You
Regards

Ben, what 'plane are you attempting to fly at that alt? Not the B738 I hope...

[EHM-1671 Ben]

I just tried to see how high I could fly in a LearJet and I got to 40,000ft.

When I last tried to see how high I could go I was in a Boeing 777... can't remember where I was though. Another time when I was flying over the Gulf of Mexico, I struggled to maintain 29,000ft!!!

in Singapore Dollars, its more expensive than FS itself but in Euro, it is $31.90 and in US $38.90.

You could check out the website http://www.fspassengers.com/

Javier,

Your best bet for fuel burn figures is to estimate them... The actual fuel burn depends on weight, weather, altitude etc so exact figures need a fair bit of calculation.

You can guesstimate them quite well by dividing the aircraft's maximum range by it's fuel capacity OR by doing a test flight for an hour at cruising altitude in calm weather and seeing how much fuel that uses. These figures will probably be accurate enough... Obviously when fuelling the aircraft for a flight don't forget to add some extra for diversions, emergencies, holding time and to allow for any really fat passengers

I do not know how to convert litres to pounds. Is there a formula for this?

FSP uses Pounds...

[EHM-0654 Murray]

I'm pretty sure there is a setting in FSP for units, but... a quick Google later...

1 litre of AvGas = 1.58lbs
1 litre of JP4 = 1.76lbs

(Or just get the figures out of the FLogger - in works in lbs as well...)

[EHM-1821 Javier]

I have found the setting and changed it. Thanks Murray. I didnt even think of it.

I would prefer it to be pounds though...

[EHM-1821 Javier]

Thanks for all your help;D;D;D

Can anyone help me calculate the C208B's range and fuel burn?( nm per gallon)

It is getting my brains to go nuts:]

Thanks

There should be a gauge in the plane telling you how many gallons your burning per hour. Use that, with how long your flight is.

[EHM-1671 Ben]

The guage is FF, or fuel flow (per hour). There is a rough estimate as to how far away you are from your arrival airport in the handheld GPS, so the hours from your destination x the indicated fuel flow should give you your total fuel consumtion for a flight.

The downside of this being that you actually have to be in the air for this to happen, which (on a class 7 flight) may be too late to go back and get some more!!

By the way, what is a C280B? I've never heard of it!

[EHM-1343 Jonathan]

Cessna 208 Grand Caravan Microsoft Default plane...here is the PIC version on approach...



should jolt your memory

[EHM-1821 Javier]

i am not too good at converting units so i guess i'll just have to use the gauge as a reference.

Thanks

[EHM-1821 Javier]

Today I made a flight and i landed with barely enough fuel.

after some calculations, this is what i have:

B734 - 168 gallons/hour
B744 - 600 gallons/hour
B773 - 13060 pounds/hour
C208 - 410 pounds/hour

Is this correct? someone check for me.
If possible could someone convert them into gallons for me?

Thanks

Hi Javier

I do not fly the 744 or the 773 enough to say what the fuel burn will be, however the 738 will burn approx 5000lbs/hr at 0.8M at  flight levels of around FL300+. To convert Gallons to LBS you multply by 6.7 and vice versa.

what is the unit used to mesure the amount of fuel eg.pounds per hour?

because in the 737-400, it was 3.8 for both engines and i  figured that it could not be pounds or maybe gallons.

[EHM-1570 Bruce]

The figure shown on the engine guages are usually in thousands of pounds/hour so your instrument is showing 3.8, this is 3800LBS/Hr
