mcfleck Posted October 5, 2018 Share Posted October 5, 2018 Hi guys, doing some longer missions recently I used the 3 droptank loadout for the hornet and came accross some oddities (at least in my oppinion). I thought if you use external tanks, you want to get rid of them as soon as possible due to the drag they produce. Normally I would assume you first want to clear your wings with the highest priority. So I would expect that the fuel pumps first use all the external wing tanks and only when they are empty switch to the center tank. What I observed is, that the fuel is drained equally from all external fuel tanks. That is not the most efficient method I think. I use to stop the fuel flow from the center tank manually untill the ext. wingtanks are empty but i get a warning doing this. So what is the supposed procedure? Is it really meant to be that way that in "auto" mode all external tanks will be used equally without any deeper logic? Link to comment Share on other sites More sharing options...
macedk Posted October 5, 2018 Share Posted October 5, 2018 U need to look up the fuel system in the real hornet manual :) Very complex system :) OS: Win10 home 64bit*MB: Asus Strix Z270F/ CPU: Intel I7 7700k /Ram:32gb_ddr4 GFX: Nvidia Asus 1080 8Gb Mon: Asus vg2448qe 24" Disk: SSD Stick: TM Warthog #1400/Saitek pro pedals/TIR5/TM MFDs [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
WildBillKelsoe Posted October 5, 2018 Share Posted October 5, 2018 So you want to rationalise the fuel usage on external tanks by prioritising certain tanks to be fed from over others? AWAITING ED NEW DAMAGE MODEL IMPLEMENTATION FOR WW2 BIRDS Fat T is above, thin T is below. Long T is faster, Short T is slower. Open triangle is AWACS, closed triangle is your own sensors. Double dash is friendly, Single dash is enemy. Circle is friendly. Strobe is jammer. Strobe to dash is under 35 km. HDD is 7 times range key. Radar to 160 km, IRST to 10 km. Stay low, but never slow.

Tenkom Posted October 5, 2018 Share Posted October 5, 2018 In real life they never drop the tanks unless it is a real emergency at which point they probably want to ditch them all regardless of what's in them. And for this reason it makes sense to drain them at an equal rate. They probably didn't have dcs multiplayer in mind when they designed the fuel-flow logic in the f18 :) Link to comment Share on other sites More sharing options...
mcfleck Posted October 5, 2018 Author Share Posted October 5, 2018 So you want to rationalise the fuel usage on external tanks by prioritising certain tanks to be fed from over others?Basically yes. The internal tanks are fed by the external already. So if your external tanks are dry, you will still have a full internal fuel load. A simple logic by default would be enough: If external tanks' fuel state > 0 Then stop using the external centerline tank I have not seen this logic in the hornet and that is what I was curious about. I am not 100% sure, but as far as I can remember the F16 did it that way (my memmory can be wrong, have not touched the other sim for a long while). Assuming this specifically is not WIP, what is the common procedure for this case? Manual override? Or just use it as it is and drop all the tanks simultaneously? Maybe i should do some measurements and see if there is a difference, but theoretically there should one. Link to comment Share on other sites More sharing options...
Svend_Dellepude Posted October 5, 2018 Share Posted October 5, 2018 One thing I noticed is that the override switches for the wing and CL tanks doesnt work respectively for override or stops transfer from all regardsless which switch is on or off.

dondiablo Posted March 13, 2019 Share Posted March 13, 2019 Is the following assumption correct? With Override enabled, the internal wings should receive fuel even with INHIBIT enabled. Link to comment Share on other sites More sharing options...
