What's happening on a 777 if the AOA probes block at the same angle ?
Is there a possibility for one protection to take over and for the airplane to ignore the pilot's inputs like it did happen on a 330
Continued activation of the stickshakers & increased column force in the nose up direction.
Don't know the effect on the Flight control computers.
...A330 pilots SS input is not 'ignored', a further nose up input will not be possible if AoA [when blocked] ~ AoAmax.
Roll control will not be affected and SS ND input (if situation permits) will cancel the hi alpha protection
.....but if AoA vanes are still blocked it will reactivate the hi alpha protection on each SS NU input.
BTW how many AOA probes on the 777 ?
2 is correct! and like the Airbus of the vane type.
