Question

Why do we deflect ailerons into wind on crosswind takeoffs?

a) To increase fuel efficiency
b) To prevent the downwind wing from rising
c) To improve passenger comfort
d) To enhance lift production

Answer 1

Ailerons are deflected into the wind on crosswind takeoffs to prevent the downwind wing from rising, ensuring a balanced and safe takeoff.

Step-by-step explanation:

We deflect ailerons into the wind during crosswind takeoffs primarily to prevent the downwind wing from rising. When an aircraft is taking off in a crosswind situation, the wind can create a force on the downwind wing that would lift it, potentially leading to a loss of control for the pilot. By deflecting the ailerons into the wind, the lift on the upwind wing can be increased slightly while simultaneously reducing lift on the downwind wing. This action helps to balance the lift forces on both wings, allowing for a safer and more stable takeoff. This technique is not about improving fuel efficiency or passenger comfort, nor is it directly about enhancing lift production, although a balanced aircraft indirectly contributes to these factors by allowing for a stable and controlled ascent.
