Gravity Feed of Fuel on Jetliners
Hi All,
I would like to seek your perspective on the principle behind gravity feeding of fuel on jetliners?Why is there a particular ceiling for gravity feeding of fuel?What is the determining factor as to how high an aircraft should fly in order to start gravity feeding?I understand that the plane must be banked at a certain angle (usually above 2 or 3 degrees) on the lighter side in order to initiate gravity feed,however if it is the centre tank that is affected,how then do we gravity feed the fuel into the center tanks?
Thank you once again for shedding some light on the above inquiries.
Best Regards,
