Which of the following is a valid interpretation of 'turn west to parallel power lines'?

• A. Turn east to parallel power lines
• B. Turn west to parallel power lines
• C. Turn north to parallel power lines
• D. Turn south to parallel power lines

Answer: (B)

When you see a directive like turn west to parallel power lines, the goal is to end up flying in a direction that runs alongside the lines, and the instruction tells you which way to start turning. The power lines are oriented East-West, so a track heading West is aligned with them (parallel). Starting a turn toward the West places your eventual flight path on a heading that runs alongside the lines, meeting the “parallel” requirement.

If you were to turn in other directions, your resulting track would not be parallel to those East-West lines. The instruction explicitly specifies turning toward the West, which is the direction that achieves the desired parallel alignment.
