uneven usage of fuel in tanks 1 and 2, need for manual balancing?

[gulredrel]

Hello,

 

I wondered last time I flew the Hind. Started only with around 1000 litres of fuel and flew quite a while.

Tank 2 120 l warning light came on. I checked the individual tanks with the fuel gauge selector. T2 was down but T1 had more than 200 l remaining.

After running tank 2 completely dry, tank 1 contained around 100 l remaining fuel, both engines still running; so from the diagram in Chuck's Guide (thanks @Charly_Owl) I think both feed the same line distributing fuel to the engines.

Does the uneven usage come from maneuvering, yawing and slipping while flying or different feeding from tanks 4+5 to 1 and 2?

Should the amount of fuel be manually balanced between the tanks or is this normal and not critical?

 

Thanks

Jens

It’s normal, that’s why you have separate indicators for 120 L in tank 1 and 2. When tank 2 light goes on you need to think about getting home, when tank 1 light 120 L goes on you need to think about possible emergency landing it is meant to give you a time scale, if they went off at the same time you would only have one indicator of low fuel instead of two alerting you of different remaining fuel levels, and there would be no reason for desperate indicators

Stacked warning lamps to create panic and even more panic  Will treat it like this, thanks.
