CF-18 Hornet can "differentiate" its large all-flying, horizontal tails to roll the airplane. Those horizontal tails are HUGE, half the span of the main wings! This can come in handy when all the electronics quit and the pilot only retains hand-hydraulic control via the control stick. When electronic auto-pilots and electronic stability augmentation systems fail, they lose control of rudders, flaps and speed brakes. It is rumored that only a single Canadian pilot has successfully landed a disabled CF-18 on cold Lake.s 11,000 foot runway.Hmmm, if someone find photo shows foreplan could all-move differentially not only synchronously, which will be very much significent!
I will talk this after it be found
