Landing essentials
Whether you can land, whether you can refuel, and how customs works here.
Overview
Sonora Municipal Airport (KSOA) is a public-use, non-towered field in Sonora, Texas, sitting at 2,140 feet elevation and serving as a general aviation point of entry for the surrounding ranch country of West Texas. The airport is unattended, with a single paved runway and solar-powered field lighting activated by pilots via CTAF. There is no customs service onsite; the nearest customs airport is KDRT, roughly 74 nautical miles away. Business aviation activity here is light, consistent with its role as a modest-tier facility supporting nearby ranches and the town of Sonora rather than commercial or high-volume operations.

Operating constraints
Sonora Municipal has published operating constraints in three categories: access, runway notes and other notes.
A fence 6 to 15 feet high sits with zero distance across the approach path, and brush up to 15 feet high sits within 0 to 25 feet of the approach.
There is also a 32-foot road at 201 feet distance, with an approach slope of 0:1.
Non-standard solar-powered lights on runway 18/36 operate from dusk to dawn. Pilots activate the REIL system for runway 18 and 36, as well as the PVASI for runway 18 and 36, via CTAF.
The runway lighting system uses solar lights.
An 8-foot fence lies 90 feet from the runway with 0 feet of buffer; a 25-foot road lies 122 feet away with 0 feet of buffer; a 50-foot pole lies 32 feet away and 233 feet left of centerline; a 28-foot tree sits with 0 feet of buffer, 153 feet right of centerline.
Runway markings are faded.
At the displaced threshold, the approach ratio is 0:1 over an 18-foot fence located 195 feet to the right.
At the displaced threshold, the approach slope is 0:1 over a 51-foot tree with zero distance, located 215 feet to the right.

Frequently asked questions
What runway does KSOA offer for business aviation traffic?
Sonora Municipal (KSOA) operates a single asphalt runway, 18/36, measuring 4,037 feet long and 60 feet wide. This is the only paved surface at the field, so all fixed-wing traffic uses this runway regardless of wind direction. There is no parallel or crosswind runway option at this airport.
Is KSOA a towered airport with regular staffing?
KSOA, Sonora Municipal Airport, is a non-towered field listed as unattended (UNATNDD) in official data. Pilots should expect to coordinate using CTAF procedures rather than tower instructions. Lighting is pilot-activated, and there is no on-field personnel presence to confirm during operations.
How does KSOA handle customs and international arrivals?
Sonora Municipal does not have customs service onsite. The nearest customs facility is at KDRT, located approximately 74.17 nautical miles away. Operators planning international arrivals into KSOA should route through that customs airport first, as no CBP processing is available at Sonora itself.
What obstacles affect the approach to runways at KSOA?
Multiple close-in obstructions are documented near the approaches at Sonora Municipal (KSOA), including fencing, brush, poles, trees, and a road within a few hundred feet of the runway ends. Approach slope ratios noted in the airport remarks are as low as 0:1 over a fence and over a tree near the displaced threshold. Crews should review published obstruction data before planning approaches, particularly on the side with the displaced threshold.
