747 System flaw???
Hi,
I am doing a project on flight controls and part of it is on the hydraulic systems. I have looked at the 747-200 for an example.
I am curious as to why boeing have designed somthing in a paticular way, could somone tell me? If all four engines were to fail like on BA009, the only hydraulic system remaining is No.4, however this services the right inboard and right outboard aileron. The left inboard and outboard ailerons are serviced by hydraulic systems No. 1, 2 and 3. This means that the only ailerons left working after a total engine failure would be the ones on the right wing. Why did boeing not put one of the left ailerons and one of the right ailerons on No.4 instead of two right ones? Surly this would result in better handling??????
I am not sure if this is the same on the 400's.
Cheers
Richard
