Question 11

To roll an airplane to the right, the left aileron goes down (increasing lift on the left wing) and the right aileron goes up (decreasing lift on the right wing), causing the right roll. So the left aileron is down and right is up? Wait, no—wait, aileron operation: when you want to roll right, left aileron down (more lift on left, so left wing rises? No, wait, lift: if left aileron is down, the left wing's camber increases, so more lift, so left wing goes up, right wing goes down? Wait, no, I think I got it reversed. Wait, ailerons work in opposition: to roll right, left aileron goes down (so left wing generates more lift, so left wing rises, right wing falls? No, that would roll left. Wait, no—correct: when you move the control stick right, left aileron goes down (increases lift on left wing, so left wing goes up) and right aileron goes up (decreases lift on right wing, so right wing goes down). Wait, no, that would make the plane roll right? Wait, no—if left wing goes up and right wing goes down, the plane rolls to the right (since right wing is lower, left is higher). Wait, but the question says "to roll the airplane to the right", so left aileron: down, right aileron: up? Wait, no, maybe I mixed up. Wait, standard aileron operation: for right roll, left aileron down (increases lift on left, so left wing rises) and right aileron up (decreases lift on right, so right wing falls). So the left aileron is down, right is up? But the options are: a) up, down; b) down, up; c) neither. Wait, the question is: "the aileron(s) on the left wing should be ____ and the right wing should be ____". So left: down, right: up. So option b: down, up.

To roll the airplane to the left, the right aileron should be down (increasing lift on the right wing, so right wing rises) and the left aileron should be up (decreasing lift on the left wing, so left wing falls). So the right aileron is down, and the left (though the question cuts off, but for the right aileron: down. Wait, the question is "the right aileron should be ____ and the [left?] aileron should be __". But the visible part is "the right aileron should be ____". To roll left, right aileron down (so right wing gets more lift, rises; left aileron up, left wing gets less lift, falls, causing left roll). So the right aileron should be down. Assuming the options (if any) include down, but since the question's options are cut off, but based on the pattern, for left roll, right aileron down, left aileron up. So the right aileron is down.

Answer:

b) down, up
