How many spoiler panels are on each wing?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

Spoilers are panels on the upper surface of the wing that disrupt lift and add drag. They’re used for lift dumping on landing and can also help with roll control. For this aircraft, there are three spoiler panels on each wing. Deploying all three during landing provides enough lift reduction and braking without adding unnecessary weight or complexity. If there were only two panels, lift-dump capability would be reduced and handling could be less stable; with four or five panels, the wing set-up would be different and isn’t required for this model’s performance and control characteristics. So the correct count per wing is three.
