Runway 15/33 is shorter, at 3,146 feet long and 100 feet wide, also asphalt. A third listed surface, H1, is an 80-foot concrete pad. Both main runways carry pavement classification numbers, with PCR values of 550 and 220 respectively, reflecting different load-bearing capacities.
Are there restrictions on airline operations at KMVN?
Yes, both runways at Mount Vernon Airport carry the same operational limits. Runway 05/23 and runway 15/33 are not available for Part 121 or Part 380 scheduled passenger operations exceeding nine passenger seats, or for non-scheduled passenger operations exceeding thirty passenger seats. Unscheduled air carrier operations larger than thirty passenger seats require prior permission, arranged in advance through the airport manager. These limits apply to both runways identically, so operators planning larger passenger flights need to confirm eligibility before scheduling.
Is fuel available at Mount Vernon Airport?
Mount Vernon Airport, KMVN, stocks both 100LL avgas and Jet A fuel. The field is attended daily from 0630 to 2000 local time, covering the hours most operators need for fueling support. Runway lighting also ties into the attendance pattern: the MALSR on runway 23 and the runway edge lighting on 05/23 and 15/33 activate via CTAF, with the 15/33 and 05/23 edge lights limited to night-only activation. Pilots should plan fuel stops and lighting needs around these published hours and activation rules.

An approach ratio of 34:1 applies over trees located 2,583 feet from the displaced threshold, 158 feet right of centerline. An 18-foot railroad obstruction also lies 238 feet from the runway end, 498 feet right of centerline, on a 2:1 slope. Pilots flying visual or non-precision approaches at KMVN should account for these documented obstacles.
