The final wheel rotation during towing should be performed in which orientation to align gears and relieve tire twisting stress?

• A. In a straight line
• B. While turning
• C. In a circular arc
• D. At an angle

Answer: (A)

When finishing the tow, the final wheel rotation should be in a straight line. Keeping the wheels rolling straight aligns the tire contact with the tow path, so the load is directed along the wheel axis rather than across the tread. This straight-line motion minimizes tire scrub and the twisting forces that occur if the wheels are rotated while the aircraft is turning, at an angle, or along a curved arc. Rotating in a straight line also helps keep gear geometries and linkage loads in their intended alignment, reducing wear on tires and preventing stress on the wheel assembly. Rotating during a turn or at an angle would introduce lateral forces, increase tire wear, and could stress the steering/gear components, making straight-line rotation the best practice.
