In terms of lateral positioning relative to Langley Road, where must aircraft be located?

• A. East of Langley Road
• B. North of Langley Road
• C. West of Langley Road
• D. South of Langley Road

Answer: (D)

The key idea is using a fixed ground reference line to define where you may be. When an instruction specifies being on a certain side of Langley Road, you must locate yourself on that indicated side of the line. Here, the instruction requires you to be south of Langley Road, so you must position the aircraft on the southern side of that road. This keeps you in the designated sector or pattern area and away from other airspace or operations. Being east, north, or west of the road would place you on the wrong side of the boundary.
