What is the sector that MCB is in?

• A. H26 PCU LO
• B. H28 PCU LO
• C. H29 PCU LO
• D. H27 PCU LO

Answer: (D)

MAP sectors are defined by a horizontal boundary block and an altitude portion, so a code like H27 PCU LO tells you exactly where the airspace is: the horizontal sector is the H27 block, controlled by the PCU, and the LO indicates the low-altitude portion. The MCB position on the MAP chart sits inside that H27 PCU LO area, so it is the sector MCB is in. The other blocks (adjacent horizontal sectors or different altitude levels) don’t match MCB’s location on the chart.
