Imagine O'Leary told airbus to make a cheap airbus 320 version, without normal or alternate law. So they would be much much cheaper.
Well, he would be dissapointed. They cannot certify such aeronautical aberration.
The Airbus in direct law is much different than a 777 in direct law. It doesn't even have a proper pitch trim. We have a THS wheel, but we have no stick forces that we can trim.
In direct law you can fatally and brutally overstress the airframe with inputs that would not seem dangerous in normal or alternate law. In a 777 I believe you would still need to exert very high forces on the yoke to do that, in direc law.
Airbus Direct law is highly undesirable... Because it is dangerous. In the simulator, after a go around with a dual hidraulic... How does it feel? Conventional? No way! Normal and alternate feel conventional. Direct is more like a 767 with the yoke artificial feeling inop. MANOEUVER WITH CARE is not a silly ECAM line. You better manoeuver it with care!
With the trim wheel you don't trim forces, but you have to ease back the sidestick to neutral as you move the wheel, resembling the action of trimming. It is just like the microsoft FS with a joystick? That is NOT conventional. It doesn't feel right for a pilot instinct.
