Roll Control

Roll control is provided two ailerons and five spoilers (2 to 6) per wing. The aileron deflection is ± 25° and the spoiler max deflection is -35°. Deflection is reduced in CONF 2 and 3. .hey are hydraulically powered and signaled from the PRIM computers. If all 3 PRIM computers fail, the SEC computers take over. Each aileron is driven by two electrically signaled servo-controls which are connected to the PRIM and SEC computers.

The flight controls system page shows the spoiler and aileron movements for roll control. Loss of 2 hydraulic systems will not cause a loss of roll control.

In flight, holding the side stick command will result in a roll bank of 67 degrees. The Flight Control System limits the bank angle. When the side stick is released, the bank angle is reduced to 33 degrees.
