I am guessing he had setup RTE 2 as well

I have a question: Is the fuel management automatically in the -8? I think there is an "AUTO" mode like it is in the T7,  right?

If you mean the tank to engine no, this still needs to be done by the crew.

There is an AUTO option in the FMC options that allows to automatically go to tank/engine but this is not an option in the real plane.

What "auto" mode was there in the 777?

I ment the fuel pump switches set to "AUTO". I thought that the fuel /tank management in the -8 is automatic.

This is not a thing.

Ditto what Kyle asked..... there is not an AUTO fuel pump position in the 777.  When CWT falls below a specified level for given flight conditions then there is an advisory message that the crew must shut off the pumps.  This is common to all Boeings, but it is not automatic.

As for the 748 fuel management, it is similar but not the same as the 744 and as in all cases there is no automatic fuel management.  So this begs the question as to what you are referring to? Be specific and lets see if we can straighten this out.

You and Kyle already answered my question ;). I only wanted to know if the fuel management in the 748 is similar to the 747. Thank you 

The key word being similar- NOT the same 🙂

Does anyone know why it is not automatic tank to engine on the 744/748? What is the logic behind it?

I can't really unterstand why Boeing did not automated the tank to engine logic on the 747-8. It seems that the -8 is not so advanced like i thought

I don't know, but my guess:

Automating the fuel system would require a complete redesign of the FSMCs and other associated equipment. All this work would need to be tested and certified and that would cost an awful lot of money for very little reward.

It would also be another difference to the 744 which would creep closer to a separate type rating, something which would be very unpopular with airlines - why 'upgrade' if you're going to have to spend millions retraining your entire workforce?

They probably forgot to take into account the requirements of a few thousand fussy flightsim enthusiasts

Its also part of the reason the 748 sold so poorly.
