747-400 >FUEL TANK/ENG
Folks... I just noticed that the Boeing wiring schematics show a 120 second time delay in the ">FUEL TANK/ENG" EICAS message logic.

Is it normal to get the message when the inboard wing tanks are a few hundred kilos below the outboards rather than when the tank levels are equal?

Thanks!
