Hey all,

Being a real world pilot, I am ashamed that I don't know what is going on here, but perplexed at the same time.

I would imagine that you can xfeed fuel from any one tank to any engine on the 707, but I am unable to do that...

I can only get the No 2 and 3 running at the same time, or No 1 and 4.  I am testing to see if you can run all 4 engines with fuel only in tanks 2 and 3.  I have been unsuccessful.  It seems counter-intuitive, but rotating the fuel manifold switches (xfeed switches at the bottom), the only work to let 2 engines run at once.  Turning a feed switch, will kill one engine while igniting the other engine...

Is it just me, or are you required to have fuel in tanks 1-4 to be successful?

Thanks!
