dove fuel gauge

just started to use the dove, came across possible fault with the fuel gauges. the gauge shows in main panel as 42galls, but if you place curser over the gauge it say's 52galls. which is the correct reading.

If your not running the FlyNET client you can go to the fuel menu in flight sim to confirm with one. But this thread should probably be moved to the CBFS forum.

David..

I have quite literally flown the Dove around the world and have not had a problem with the fuel gauges. It may well be that Sav calibrated the gauges to read imperial (or the imperial equivalent of US gallons).. I honestly can't remember now but I'll have a look at it to see if I have the same discrepancy

[EDIT] David.. I took ARDE from Brum to Hurn last night and noted the fuel readings. I always install an RKG Fuelstat gauge to cross-check fuelburn and mouse readings were coinciding with what the RKG was saying. I don't normally use the lower panel (I presume this is what you are looking at) as I don't like unnecessary windows open so I tend to use the RKG and/or rest the mouse over the fuel gauge in the main panel. Of course, you can't see what the gauge is actually reading as the needles are out of view but I've never found that a problem. The needles DO read lower than 'mouse look' and I'm pretty certain that this was done so that they display UK gallons. The correct 'sim' value is what is indicated by mouse look so either use this or take the needle reading and know that you have more sim gallons than you're seeing

thank's dave. now that i know the gauges show less than actual, in my favour i live with it.

Some will probably consider this cheating but I ususally press Shift-Z a couple times so the percent of remaining fuel is shown at the top of the screen. Periodically divide the distance remaining by the percent of fuel, as long as that ratio is going down you know you will get to your destination.

that's ok your not the only one that uses that info for the fuel consumption. this was my first run with the dove and so was always looking at the fuel gauge. i have sort of worked out she burns 1kg per nm and so that's my bench mark, for now.

Hi David..

If you use a joystick and rely soley on the throttle, you get a much greater fuel burn off the old girl. Normal cruise is +2 boost at 2400rpm which will give you a very meagre 118kgh. A comparative figure for using ONLY the throttle is 125kgh at +2 boost (this leaves the rpm at 3000) so it certainly pays to open the pedestal and fly her to the numbers

AHHH HAAA!!! the mystery opens, i've just used the throttle and wondered why the documents were saying 2400rpm when the lowest i could attain was 2930rpm. with what you have said i'll try the pedestal on my return journey, will be a few days. got myself planed with DC3 and Argosy flights to norway. Done two tours of duty over there and loved the place. winter exercise's.
i thought that was cold until i came to Ottawa.

Your other settings are..
3000/+7.5 198kgh (takeoff max five mins)
2800/+6 180kgh
2600/+4 154kgh
and the previously mentioned 2400/+2 125kgh.

Obviously, there is not much you can do about your takeoff power so that will remain at 198kgh. However, you will see a reduction in fuelburn at +6 if you pull the rpm down to 2800 and likewise for 2600/+4. The figures above are for using joystick throttle only

Get her off the deck using 3000/+7.5 and unless you are in a hurry to burn gas OR you have a particularly challenging climb, you should be able to dispense with 2800/+6 and 2600/+4 and plump her straight on to 2400/+2 when you see around 120kts on the ASI. I've only been poodling around at 5000ft and 2400/+4 is sufficient. Should you need to go higher.. you'll need to keep an eye on the boost as this will fall (obviously) the higher you go

Also, you will probably eek a few more knots out of her at the correct rpm. In still air and using only the joystick throttle, you'll see around 157Kias.. with 2400/+2 you'll be seeing 160.

Glad you're enjoying the old girl :dance:

[edit] David.. further to the above, I ran ARDE from Jer to Hurn this morning and noted the burn figures for you using the pedestal to control RPM. There is no change at full power (3000/+7.5 198kgh) or at 2800/+6 - 180kgh but at 2600/+4 a reduction from 154kgh to 148kgh and with careful adjustment of throttle/RPM at 2400/+2.. you can expect to see 116kgh. Throttle is 73% for +2 and RPM at 74% for 2400. Sweet as a bird
