Which pair has a distance of 48 miles?

• A. DESKE to GLH
• B. SQS to UJM
• C. MEI to MLU
• D. MHZ to MCB

Answer: (A)

Distances on enroute charts are measured as great-circle distances—the shortest path over the Earth between two points. This reflects the actual flight distance you’d follow rather than a straight-line on a flat map. DESKE and GLH are geographically very close in Mississippi, giving about 48 miles on a great-circle route. The other pairs connect airports that lie farther apart, so their distances exceed 48 miles. Therefore, the DESKE to GLH pair matches the 48-mile distance.
