Yep, it seems I was wrong.

I think Ближний means close, despite what google says.

Disclaimer: my knowledge of Russian is also very limited.

You're right, thanks
Even the translation from Russian to French is "close" (proche).

(one of the best translation weapon is a Russian dictionary)

This is actually really helpful; thanks mate.

I only tested the first warning light and it's on with 5014kg left (not 5590kg as suggested in the note).
(Su-27 for DCS 1.2.14)

UPDATE: the in-game values are:

Бак 4,1....5014 kg
Бак 3.......4004 kg
1.5...........1504 kg
Бак 5.......1004 kg
0.6.............604 kg

Based on the Su-27SK manual, there should be 4 fuel tank groups:


Схема расположения топливных баков


The Su-27 has a rather precise fuel consumption sequence elaborated to preserve its maneuverability/balance (Center of Mass (CM)) (depending on the initial fuel quantity):


Based on the sequence, the first warning light is on when the tanks 4, 1 and most of the wings tanks are empty (tank 3).
On the fuel gauge, the lights do not exactly correspond to an empty tank (=Бак):
  • Б4,1 probably stand for Бак 4 and 1 (9400-5014=4386kg --> Su-27SK tanks 1+4=4180kg | that's close enough )
  • Б3 obviously stands for tank 3 (5590-4430=1160kg (using the note | close to the Su-27SK manual (1060kg)))
  • 1.5 is the 1500kg warning (+ vocal warning message)
  • Б5 (880kg warning (note)) should mean there's a tank 5 (?) there's a 800kg vocal warning message too.
  • 0,6 is the bingo fuel last warning (w/ vocal warning message and bingo fuel vocal message)

The fuel measurement has an accuracy of ± 170 kg.

Game/sim-wise, it's pretty straight forward and there's really no problem using that gauge. The fuel is burning, the light goes on, ok there's roughly that fuel quantity left. Done.

But I'd like to know if there's a specific known structural fuel system schematic for the Su-27S?
Or if anyone could confirm there's a tank 5?
(or what it means) (I'm curious)

And if you have the exact value for the fuel quantity left for each warning lights, please do share (values added above)

Any detail would be appreciated.
Thanks!
