FUEL/MW tank bug

[saburo_cz]

10% fuel would run out before 10% MW50

 

it is OK, no problem here

it was only reason why i took external fuel with 10% fuel internal, to measure time when MW run out, and MW pressure started to go down in same time with external fuel or without it, so perhaps no MW content is effected by external fuel choice (and there is no reson for it, IMO)

 

and last one, i just confirm fact that contents of internal fuel goes with contents of MW in tank, i do not have idea if it is wrong or not (although i prefer only simply full or empty MW tank)

I sadly dont have time because of an important deadline tomorrow. Ill explain quickly again. If you have the slider set to 10% fuel you have only 8.5l (10%) of 85l (100%) MW50 in the tank. Thats how it is programmed in the flight model. The ME however shows these 8.5l as well as full tank (85l) to weigh ~70kg.

 

It has been confirmed by ED that the MW50 tank is filled proportional to fuel % loaded and I tested and confirmed it the way I described above. I am perfectly sure I am correct on this one. Just test for yourself as I did, I will just quote myself.

 

If you want to test for yourself, this is how I did. A full load MW50 takes 26 min till pressure drops and at around 28 min it is completely empty. Therefore if you load 10% fuel there should be enough MW50 for 26 * 10% = 2.6 min. Now add the remaining 2 min till complete depletion and you get around 4.6 min till the engine should start running rough. For a testflight add the external fuel tank, so you dont run out of fuel and after around 4.5 min the engine starts running rough. Just look at the onboard clock and speed it up.

Or just take 50% fuel (& MW50) and forget about the external fuel tank, I just didnt like to waist time. The MW50 tank will empty after ~15 min and that is because it is only 50% aka 42.5l aka 35kg filled, while ME indicated a 100% aka 85l aka 70kg filled MW50 tank. Just switch MW50 on & off in the according tab at 100% and at 50% and look at the weight in ME. Get it?

 

Another thing is that density seems weirdly calculated for MW50. I calculated in another thread and 85l should actually weigh around 76.5 kg not 70 kg.

You lose me here, where in the ME does it indicate that the MW50 tank is at 100%? As I can see it doesnt show the percent of the MW tank alone.

 

Are saying there is something wrong in the math, and 50% MW50 is not being calculated correctly in the total weight?

[NineLine]

NM, I did the math I think I am getting what you mean now.

[RAZBAM_ELMO]

I think if we could get a separate slider for the % and a drop down menu to select MW/ B4, or empty. I think that would be a simple yet effective solution.

[NineLine]

Hey guys, seems there is a bug with ME, so the FM itself is ok, but the weights dont display correctly.

[rel4y]

Thats what I thought. Thank you Sithspawn!

I´d say this statement is plausible.

I found a source in the "K4 Handbuch" stating that specific weight of MW50 is 0,9 kg/Ltr.

 

85 Ltr / 0,9 kg/Ltr = 76,5 kg

the weight of the aircraft fuel tanks (full or empty) do not affect the FM? ..are you sure? :music_whistling:

Trolling? or is that a serious question?

Moderators should not be so defensive on this forum. I someone wants something to be improved it doesn't mean he has something personal with you or ed. So it's not polite to call someone a troll ;).

[Anatoli-Kagari9]

The weight of the MW tank, filled with either MW50 or B4 fuel DOES AFFECT the flight dynamics in the present version, AND, the Moderator statted, in this thread, that it's probably due to a bug in the present ME ( Mission Editor ) that we can't properly see it displayed there.

 

But all of my tests give positive signs of the weight in that tank having very noticeable impact on the aircraft performance ( starting with a pitching up moment... ), and I am using the pitch curves suggested in another thread to overcome not being possible to set the elevator trim tab.

 

I believe one of the next patches will fix the Mission Editor too.

I hope sooner than later of course, I dont have a timeline though.

1) I didn't call him a troll, but past history shows you he is more inclined to ask questions to incite a reaction. That is basically the definition of trolling, I was giving him the benefit of the doubt, and asking him if he really had concerns, or if we were going to go down the same path again.

 

2) As per #1, generally his questions are more about what he 'thinks' wrong, and has been told isnt wrong, but refuses to accept that, breaking the rules, and asking redundant questions because he doesn't understand this.

 

3) Your post has nothing to do with the topic, please stay on topic, read the thread title if you are not sure what is being discussed. This is also a rule violation. If you have any more questions about this, feel free to PM me, or another moderator if you so choose.

 

I dont want to have to close this thread, there really is a bug here, its partly fixed, and I would love to keep it open till its completed, but if someone is going to turn this into a thread about something they are upset about, I will be forced to close it. Please review the rules and use the PM system to share your concerns.

Please, answer the question,

the weight of the aircraft fuel tanks (full or empty) do not affect the FM? ..are you sure? :music_whistling:

Yes or Not? :huh:

 

P.D.

Asking questions that incite a reaction for studing a problem is a research methodology. ..That is not trolling. :smilewink:

Why should he be sure of something he did not say?

 

He said

Hey guys, seems there is a bug with ME, so the FM itself is ok, but the weights dont display correctly.

Iirc, reports in this thread suggest that the FM behaves as if the MW tank weight is considered by the FM. Therefore he mentioned that the FM is correct, but that there is probably a problem with the Mission Editor that does not show the weights correctly in this case.

 

So, what direction does your research methodology lead you know?

[NineLine]

Yes or Not? :huh:

 

Its already been answered, you should 'research' the thread and find your answer.

Let's go to re-center in the topic.

We have a error with weight & balance, ..am I Right? :music_whistling:

[RAZBAM_ELMO]

No just the way it is displayed in the ME

So ..the weight shown in the ME (Mission Editor) is diferent of the weight modeled in the FM??

This bug is only for the ME (MEsserschmitt) or for all airplanes in DCS??:music_whistling:

[Ala13_ManOWar]

Que es un problema del editor que enseña un número mal Otto, no afecta al avión.

 

S!

S!

ketelokrestú ..que diría un vasco, .. Manowar, ..los cambios de peso en el editor deberían afectar al FM del avión, no son solo numeros mal.

 

In english please,

I understand that is a discrepancy between weight shown in M.E. and the weight modeled in the FM. ..Changes of weight in the M.E. must affect to the weight in the FM. .. right??

[NineLine]

You have a switch, it can go to position 0, 1 and 2.

 

When you move the switch to 2, it is on 2, but it displays its only on 1.

 

It is simply the numbers displayed in the ME that dont show correctly. Everything in the FM reacts as you would expect (full tank, partial tank, MW50, no MW50, etc)... or atleast how all of us expect.

[Anatoli-Kagari9]

And even better,

 

one can easily test the effects, since having the MW50 totaly or partially ( proportional to Fuel ) filled does make a noticeable difference in your CoG and stab trim need.
