Which Spoiler panels are deployed as speedbrakes?

• A. 1,2, and 3
• B. 2,3, and 4
• C. 1,3, and 4
• D. 1,2,4

Answer: (B)

Spoilers that serve as speedbrakes are the wing panels that rise to spoil lift and create drag. On the A320, the middle three spoiler panels are the ones activated as speedbrakes in flight. The innermost spoiler is configured primarily for lift-dump on the ground and isn’t used as a speedbrake during flight. That’s why the correct combination is the middle three panels. The other options would include or exclude the wrong panel, which doesn’t match how the system is designed to work.
