Frequently asked questions
What runway does KCZT offer for business aviation traffic?
Dimmit County Airport (KCZT) has a single paved runway, 13/31, measuring 5,003 feet long and 75 feet wide with an asphalt surface. This length accommodates most light and midsize business jets operating into Carrizo Springs, Texas. The airport is non-towered, so pilots coordinate traffic using standard self-announce procedures on approach and departure. There is no parallel or crosswind runway, so wind conditions favoring one direction over the other should be checked before planning an arrival.
Is fuel available on request at KCZT?
Dimmit County Airport (KCZT) offers 100LL and A+ fuel, with Jet A also available, but the source remarks note that fuel is available on request rather than guaranteed during all posted hours. The listed attendance schedule runs seven days a week from 0800 to 1700 local time. Dispatchers planning a fuel stop at KCZT should confirm availability ahead of arrival given the on-request notation. No fuel supplier is named in the airport data.
What customs options exist near KCZT for international arrivals?
Dimmit County Airport (KCZT) does not have customs service onsite. The nearest customs facility is located at 5T9, approximately 41.52 nautical miles away. Crews arriving from outside the United States and planning to clear customs will need to route through that facility rather than KCZT directly. This distance should factor into fuel and routing planning for any international leg terminating in the Carrizo Springs area.
How busy is KCZT and when does traffic peak?
Dimmit County Airport (KCZT) recorded 640 total annual operations in 2025 according to FAA TFMSC data, with 543 of those attributed to business aviation. Monthly business aviation traffic is concentrated toward the year's edges, with December, November, and January each posting the highest counts among the twelve months reported. Mid-year months such as June through August show notably lower activity by comparison. This pattern is useful for dispatchers anticipating ramp space or scheduling flexibility at KCZT during quieter periods.
What obstacle should pilots know about on the approach to Runway 31 at KCZT?
Dimmit County Airport (KCZT) has unmarked, unlighted electrical transmission lines underlying the approach to Runway 31. Because Runway 31 itself is also unmarked, pilots flying this approach, particularly at night or in reduced visibility, should account for the wire hazard beneath the approach path. This condition is noted in the airport's general remarks and applies specifically to arrivals from that direction. Runway 13, the reciprocal, is not flagged with the same obstruction note.
