MOAs are designated blocks of airspace within an ARTCC’s jurisdiction used to separate military training from civilian air traffic. The Aero Center area includes MOAs like Columbus 3 and the Meridian MOAs to the west, which lie inside that center’s airspace. Atlantic 1 MOA sits outside Aero Center’s boundaries, belonging to a different ARTCC’s region, so it isn’t part of Aero Center’s MOA set. Therefore Atlantic 1 MOA is the one that is not an Aero Center MOA.

This question is about knowing every intersection defined inside Aero Center. To answer correctly, you need the complete set of intersections designated for that airspace, not just a portion. The full list includes BOOSI, MIZZE, HEDUD, DINKY, STUEE, BARNE, ZAMMA, DORTS, HATER, RICKS, and HAZAL. Any option that omits one of these intersections isn’t the complete set. The other choices leave out at least one intersection (for example, one option lists only the first five, another lists a different subset, and another misses HAZAL). Therefore, the set that contains all 11 intersections is the correct choice.

V airways are defined by their general direction and the VORs they connect, so their description on charts is about the overall path rather than a precise line. For this airway, the published path runs northeast toward the Holly Springs area and then continues southeast toward Greene County, with a north–south segment roughly centered between Magnolia and Sidon. That makes the description “NE to Holly Springs and SE to Greene County, NS in the middle between Magnolia and Sidon” the best match to the charted route, since it captures the true diagonal progression and the central north–south portion of the corridor. The other descriptions imply end points or directions that don’t align with V11’s actual corridor, which is why they’re not correct. The key idea is that V11’s general path is described by its northeastward approach to Holly Springs, its southeast continuation to Greene County, and the central north–south span between Magnolia and Sidon.

Radials are the magnetic bearings that extend from a VORTAC. The radial to a specific airport is simply the line from the VORTAC toward that airport, read in degrees from magnetic north. To figure it out on charts you locate Magnolia VORTAC and Hawkins Field, then identify the radial that points from the VORTAC to the field. In this case Hawkins Field lies to the south-southwest of Magnolia VORTAC, so the radial is about 190 degrees. That means from Magnolia VORTAC you’d be following a direction of roughly 190° toward Hawkins Field. The other directions—south (180°), slightly southeast (170°), or more southwest (200°)—don’t align with Hawkins Field’s location on the chart, so 190° is the best match.

Diamond mileage markers along an airway show how far it is between fixes and the direction to the next fix. When you read from Magnolia toward McComb, you move left to right across the chart, so you encounter the first diamond marking along that leg first. That first diamond reads 33 miles SW, meaning the next fix along the route is 33 miles away in the southwest direction from Magnolia. The other options correspond to later markers or different directions, so they don’t represent the first mileage you’d see on this left-to-right pass.
