I just d/l the newest update 1.6 and I noticed unlike previous versions he did not turn off the center fuel pumps at TO or when they are at or close to 1000 Lbs in the center tank. This is my first flight with the new version so I'll keep you updated as to what I see on other flights.Sean Green

Hi Sean,New Fuel pump logic for Pumps with Center Tank Fuel Pump Auto-shutoffEach center tank pump will automatically shut off, after a short delay, when that pump’s sensor detects low output pressure.Fuel pump LOW PRESSURE lights may flicker when tank quantity is low and the airplane is in a climb, descent, or on the ground with a nose-down attitude. Center tank fuel pump LOW PRESSURE lights may flicker when tank quantity is low and the airplane is in cruise. One pump may indicate low pressure sooner than the other due to aircraft attitude and/or slight variation between pump inlet position. Low pressure indication may occur after center tank quantity reads zero. Low pressure light flickering can continue for as long as 5 minutes before the Fuel System Annunciator light and the Master Caution lights are illuminated for the associated center tank pump.We'd only turn them off if we get a low pressure light coming on.Regards

Great info damienw; did not know about the auto shut off. Sean

And just to let everyone knows, Damien flies the 737NG for real (and from the big left seat, too :( )So when he speaks, it's not just B.S. He knows what he's talking about.Cheers,
