Fuel selector Both i.s.o. L/R for FFS RV-7

Recommended Posts

Hi guys,I using the Flight Factory Simulations RV-7 payware.Nice little aircraft...I'm planning worldtrip with the real aircraft of this type, in a couple of years form now. So now it the time to do some routing and fuel testing with the FFS one.The aircraft comes with the Left/Right/Off Fuel selector, just like in the real aircraft.However, I like to modify it towards the C182 L/R/Both fuel selector.I've installed the C182 fuel selector on the panel, but unfortunately the Both position does not work.I can select L, R and OFF, but the middle one does not keeps it position.What do I need to change in the cfg file, to make it work please...?Thanks for your help,BigglesFlying was my first love and it will be my last one!

You can have a variety of tank names such as LeftMain, RightAux, Front and so on. Check the fuel sections on both aircraft.cfg files for tank names and other fuel differences (Number of fuel selectors etc.).CheersShad

Yes, I checked the fuel cfg file:Left main and right main are the tanksFuel selector: 1My question is ; how can I take fuel from the left and right tank at the same time? What needs to be done?Do I need to change the nr of fuel selectors ?Anybody.. please?Regards,Biggles

Hi,Did you try:(>K:FUEL_SELECTOR_ALL) for the Both position?Jan"Beatus Ille Procul Negotiis"

Hi Jan,Where should I look for the (>K:FUEL_SELECTOR_ALL) ?In the cfg file > aircraft > fuel section?I have the following things in this section;Left Main tankRight Main tankFuel type 1number_of_fuel_selectors 1electric pump 1Can you please give some more explanation on the above....Thanks,Brgds,Biggles71

Sorry about the short message.The command (>K:FUEL_SELECTOR_ALL) belongs to an XML gauge, which you can make; or by editing an existing one.Has nothing to do with the aircraft.cfg file.In that gauge you have the possibility to choose between Left, Right All and Off.The needed commands are:(>K:FUEL_SELECTOR_LEFT) (>K:FUEL_SELECTOR_RIGHT)(>K:FUEL_SELECTOR_ALL) (>K:FUEL_SELECTOR_OFF) If you cannot make it yourself, do a search in the libraries.Jan"Beatus Ille Procul Negotiis"

Jan,OK, but I've removed the fuel selector that was installed (L/R/OFF) and have now installed the C182 fuel selector on the panel.So basically I've a fuel selector with L/R/BOTH/OFF, only the switch does not stay in the BOTH position...it flicks back to L or R.I have the feeling that some setting needs to be changed to allow the selector to be working in the BOTH position.Thanks for a further word of explanation,Biggles71Flying was my first love and it will be my last one!

Hi,The Cessna fuel selector is incorporated in the "multigauge" Cessna.gau, which is C++ coded and, for me, not accesible for editing.In XML it is a piece of cake.See as an example the "Spirit of st Louis" fuel selectors.Jan"Beatus Ille Procul Negotiis"

Guys, I don't have the code in front of me now, but I believe we made it so that you could not select the BOTH position. We did this so that user who used key presses to change the fuel selector would not have problems with it selecting BOTH. Programmed like this, it will not be possible to go to BOTH.

So, if I understand it right, there is no way of modifying the RV7 with a BOTH fuel selector...? Can I use another fuel selector ? If yes, which one please?As I said, I've tried the Cessna fuel selector with the both position, unfortunately, it doesn't keep it...Is there a way to change the "code" and allowing the BOTH position?Please try to keep it simple...I'm not into XML programming etc...Brgds,BigglesPS: Youn probaably understood by now, that solving this problem is very important for me....Flying was my first love and it will be my last one!

Well,If you have the proper bitmaps, a lot of people here can make a fuelselector with left, right, both and off positions (in XML),unless, as Matt said, the design makes it impossible.Jan"Beatus Ille Procul Negotiis"

MKaprocki Could you please confirm that the codes defenitively don't allow a BOTH fuel selector...?If it does allow,... Jan I would really appreciate if you or somebody else could send me an XML Both fuel selector.Thanks again,Biggles Flying was my first love and it will be my last one!PS: Jan, veronderstel dat je nederlandstalig bent..., bedankt voor de moeite !

Hi,It is indeed possible to code your plane's fuel system in a way that the Both position remains impossible.Ask the Developers.Jan"Beatus Ille Procul Negotiis"

The reality of using auxiliary fuel tanks in an RV7(A) is this:You can use auxiliary wing tip tanks (or modified rib bay tanks) that feed by gravity into their respective main wing tanks.Then there is the option of a baggage area or right seat tank, that feeds to a 3rd auxiliary port on a fuel selector valve, which can be ordered for the real RV's. But never the less, you'll be doing "fuel management" for fore & aft CG, and left to right balance; but you cannot have a "both" selector to pull fuel from both sides at once, such as a high wing Cessna. With the wing fuel tanks & fuel selector valve below the fuel intake on the engine, whether carb or fuel injected, fuel will simply move from one tank to the other, even to the point of being forced out the fuel vents with full tanks.Considering this "real life" situation, I don't see why Flight Factory Simulations should do any modifications in the first place.

Mr Adamson,Thanks very much for your comprehensive explanation... The only reason I wanted the BOTH position, is to do some Max range tests, without having to get up very hour to change the fuel selector...I realize very well, that "real life" is different...Yes, I'm a real life pilot, ATPL +8000hrs (A330-340 Captain) and yes I've done real life non-stop flights of more than 11hrs in single engine aircraft...Thanks.BigglesFlying was my first love and it will be my last one!

Since I've been around RV's for 15 years or so, I've met many builder/pilots who have been long time commercial airline pilots. Some know a wealth of information regarding homebuilt/experimental airplanes, and others know very little about the mechanics of the subject. But then you won't see me flying a commercial passenger jet either! ;-) L.Adamson

That's fair enough...BTW, I've built a COZY3 some years ago, have sold it and I'm now seriously considering building an RV-7.Brgds,BigglesFlying was my first love and it will be my last one!

Hi Biggles. I was the programmer of the RV-7 gauges for FFS. It has been over a year since I've even looked at the code, but I am fairly certain it is not possible to use the BOTH position. We removed it to prevent any problems if it was somehow placed into that position. The only way to fix it would be to reprogram all the gauges.I can check for sure tomorrow, but I think that's how it is.

Took a couple extra days, but I did check the gauge code.It is indeed impossible to use BOTH in the RV-7. If you try to put it in that position, it will reset to OFF.

MKaprocki While on the subject of the FFS RV7...Do you have any idea if there is a way to reduce the oil consumption? It seems on the high side at 0.5qt per hr or so...Realistically I would like to have at at about 1qt per 10 to 15hrs.Best regards,BigglesFlying was my first love and it will be my last one!

How many hours do you have on the engine? It's set to burn a bit much oil at first until the engine is broken in, then it should slow down a little. I'll check the code and get some exact numbers, however there's nothing that can be done at this point. The RV-7 belongs to FFS, which I am no longer a part of. You would have to ask them for any changes.
