Frequently asked questions
What is the runway length at KOSA?
Mount Pleasant Regional, identified as KOSA, has one paved runway, 17/35, measuring 6,004 feet long and 100 feet wide with an asphalt surface. The field also lists a 44 by 44 foot concrete helipad designated H1. There is no parallel or crosswind runway, so all fixed-wing traffic uses 17/35 regardless of wind. Pilots should note there is no line of sight between the runway ends, a factor for traffic awareness at this non-towered field. The runway length supports a range of business turbine aircraft operating into Mount Pleasant.
Is there a control tower at Mount Pleasant Regional (KOSA)?
Mount Pleasant Regional is non-towered, so arriving and departing traffic self-announces on CTAF. Runway edge lighting and REIL on both ends of runway 17/35 are preset to activate at low dusk to dawn levels, with pilot-controlled activation available for daytime use or increased intensity via CTAF. PAPI on both runway ends operates continuously. For clearance delivery, pilots contact Fort Worth ARTCC rather than a local tower. These arrangements are typical of a non-towered field handling business aviation and general aviation traffic in this part of Texas.
What fuel is available at KOSA?
Mount Pleasant Regional stocks both 100LL and Jet A. 100LL is available 24 hours on a self-service basis. Jet A service applies after hours, per field remarks, meaning attended fueling follows the posted schedule rather than round-the-clock availability. The airport's general attendance schedule runs seven days a week from 0700 to 1800 local. Dispatchers planning fuel stops outside those hours should account for the self-service 100LL option and the after-hours Jet A note when sequencing a trip through KOSA.
Does Mount Pleasant Regional have customs available on-site?
Mount Pleasant Regional does not have on-site customs processing. The nearest customs facility is at Shreveport, Louisiana, roughly 69 nautical miles away. Flights requiring customs clearance should plan to route through that airport instead of KOSA. This is a routing consideration rather than a restriction on operations at Mount Pleasant Regional itself. Dispatchers coordinating international arrivals into this part of northeast Texas should build the Shreveport stop into trip planning accordingly.
What wildlife or obstacle hazards are noted at KOSA?
Mount Pleasant Regional's remarks flag deer and other wildlife on and in the vicinity of the airport, a standing hazard for pattern and runway operations. Separately, obstruction data lists a 59 foot beacon 285 feet west of the runway and a 33 foot building 256 feet west. Runway markings are also noted as discolored, which can affect visual reference in certain lighting conditions. Combined, these factors point to elevated situational awareness needs during visual approaches and taxi operations at this non-towered Texas field.
