After completing Areas 5-8, proceed toward which line and descend to what altitude prior to transiting under adjacent Mustang areas to intercept arrival to KNGP?

After completing Areas 5-8, proceed toward which line and descend to what altitude prior to transiting under adjacent Mustang areas to intercept arrival to KNGP?

• A. the Bayside, 6,000' MSL
• B. the beach line, 4,500' MSL
• C. the shoreline, 3,500' MSL
• D. the coast, 5,000' MSL

Answer: (B)

The main idea is choosing the correct transition line and altitude to align with the published inbound path to KNGP after completing Areas 5–8, ensuring you can descend on a safe, authorized corridor before transiting under the adjacent Mustang airspace to intercept the arrival. The best choice is the beach line at 4,500 feet MSL. This line places you on the proper lateral position to feed the KNGP arrival and gives you the right descent point and clearance before entering Mustang airspace. Descending too early or too late, or using a different boundary, would put you out of the required intercept path or at an altitude that doesn’t match the published arrival segment, risking spacing or airspace issues.
