About this route:
A direct, nonstop flight between Brown Field Municipal Airport (SDM), San Diego, California, United States and Alamogordo–White Sands Regional Airport (ALM), Alamogordo, New Mexico, United States would travel a Great Circle distance of 639 miles (or 1,028 kilometers).
A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the relatively short distance between Brown Field Municipal Airport and Alamogordo–White Sands Regional Airport, the route shown on this map most likely still appears to be a straight line.

- The closest airport to Brown Field Municipal Airport (SDM) is Tijuana International Airport (TIJ), which is located only 2 miles (4 kilometers) SSE of SDM.
- Because of Brown Field Municipal Airport's relatively low elevation of 526 feet, planes can take off or land at Brown Field Municipal Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
- Brown Field Municipal Airport (SDM) has 2 runways.
- In 1946 the Navy decommissioned Brown Field and turned it over to San Diego County.
- A precision approach is not possible to either runway end due to rising terrain less than six miles east of the airport.
