feature request - fill rate outer to inner wing tank too fast

[HauptChr]

Hello,

today i started to use jeehell instead of PM software.

Jeehell is working fine (ok, i need a faster PC for my MIP TFT displays - the PC was ok for PM software but Jeehell is not running smooth on it)
And so i will change my setup to Jeehell.

Fuel System :

I just played a little bit. outer Tank 700 kg. Whenn inner tank is below 1650 lbs fuel, the outer fuel runs to the inner tank.
Jeehell software simulate this feature. But the fillrate is too fast. It needs a couple of Minutes.

I did not check center tank fuel.
Center Tank :
if the center tank is being used, you have the msg “CTR TK FEEDG” on ecam memo panel.

with fuel in center tank :
engine start : center tank fuel is used.
Selecting flaps : center tank fuel will not be used. Msg will disappear. But it needs some time after selecting flaps. I did not use the stopwatch… maybe something around 15-30 seconds until center tank valves closed and msg disappeared.
After lift off, flaps 0, center tank is used again

If the fuel in the centertank is 0, it needs some time until the valves will be closed. Sometimes you may see a “lo press”

for maybe 15 seconds before the valve closes.

Around another 15 seconds, the 2nd valve had been closed

Only if the inner tanks are below 1650 lbs fuel, the outer tanks were used. The main purpose of the outer tanks is, that they reduce the wing bending and reduce the fluttering of the wings.
outer to inner tank transfer :
by gravity, tansfer valves open automaticly when approx 750 kg in inner tank. ( a special symbol appears on fuel page).

and you see a triangle on SD page

OUTR TK FUEL XFRD
mgs will be disappeared while landing checklist is visible.
But OUTR TK FUEL XFRD is visible again when landing checklist has gone, even with engines OFF

also the riangles remain visible

If you start to refuel the aircraft (REFUELG msg on ECAM memo panel)
OUTR TK FUEL XFRD and the triangles will disappear.

Hi HauptChr -- are you a real world pilot, seems like it

Could you please post your findings at http://www.christophpaulus.com/bugre..._view_page.php

This way Jean Luc can keep track of all the bugs and can fix them.

Thank you,

Ben

Hi HauptChr, welcome! Always glad to have someone with real life experience giving us insight.

From the photos it looks like that bird has the latest FMGS version that has some differences in the EIS and SD pages over the older version that Jeehell currently simulates. If I remember correctly from the old FCOM the fuel tank separation and transfer is shown by inner "flaps" that open when the outer tanks feed the inner and not with arrows. AFAIK this is simulated correctly in Jeehell, although not sure about the feeding timings where the software version shouldn't play a role.
