Landing essentials
Whether you can land, whether you can refuel, and how customs works here.
Overview
Yuma MCAS / Yuma International (KNYL) is a joint-use civil/military airport in Yuma, Arizona, operating under FAA TFMSC-tracked traffic near the US-Mexico border.

Its role as a shared Marine Corps and civil facility shapes much of its operating environment, from traffic pattern overlaps to restricted-priority arrangements for military aircraft.

Operating constraints
Yuma McAs / Yuma International has published operating constraints in four categories: access, runway notes, pavement strength and other notes.
General aviation and air carrier VFR departures should fly the runway heading and maintain 1,200 feet until outside the ATA, unless otherwise approved by the tower.
Military jet operations descend from 4,000-3,000 feet MSL to 1,700 feet MSL within 6 nautical miles southwest of the straight-in approach to runways 03L and 03R, and within 6 nautical miles northeast of the straight-in approach to runways 21R and 21L.
F-24 military fuel is available on request for shipbound aircraft. Jet A and Jet A+ are available via the FBO on a specified frequency, with availability Monday through Friday and weekends during set hours; outside those hours requires a minimum one-hour prior notice.
Restricted: flight clearance is staffed during military operating hours; contact base operations for coordination. Transient aircraft require 24-hour prior permission request, arranged through base operations. AV-8B VSTOL training to runway 03/21 may have priority Monday through Friday over military practice approaches.

All transient aircraft flying from Yuma Proving Ground require a 24-hour prior permission request submitted through base operations. All transient aircraft utilizing the military ramp also require a 24-hour prior permission request, submitted through base operations. Military aircraft requiring runway 03/21 may have priority Monday through Saturday over practice approaches.
Operating hours apply to military operations, including Yuma Intl and the FBO. After-hours access requires a two-week prior permission request submitted in writing to base operations.
For clearance delivery, contact Yuma Center Radar Approach Control.
Fixed-wing, rotary-wing, and F-35 rapid refueling hot pit servicing is available during control tower hours with a 24-hour prior permission request, coordinated on a specified frequency. Two aircraft can be serviced simultaneously. Aircraft should advise ATC and proceed to the south ramp off taxiway Z3.
When the control tower is closed, pilots must activate the high-intensity runway lights for runways 08/26 and 17/35, along with taxiways A, A1, A2, B, C, L, and Z, using CTAF.
An 18-foot windsock is located 130 feet left of the runway end.
A 17-foot windsock is located 140 feet left and 100 feet from the runway end.
A 14-foot windsock is located 110 feet left and 90 feet from the runway end.
Caution: the traffic pattern for runways 03L/R and 21L/R overlaps with the traffic pattern for runways 08/26 and 17/35.

Caution: this is a joint-use civil/military airport. General aviation and air carrier operators flying VFR must enter the ATA at 1,200 feet when assigned runway 08/26 or 17/35.
Helicopters should enter the airport traffic area at traffic pattern altitude of 1,200 feet, then descend to 700 feet prior to all runways.
Part 77 obstructions include a radar tower to the east and poles near runway 17.
FOD restriction: heavy and wide-body aircraft arrivals and departures are limited to runway 03L/21R only. Aircraft parked at MCAS Yuma's south main parking apron or the VAL back-taxi to runway 03L/21R, then taxiway D. Aircraft parked at Yuma Intl, the FBO, or the defense contractor complex apron back-taxi to runway 03L/21R, then taxiway H1 or F1. Other runways or taxiways are not authorized for this purpose.

Frequently asked questions
Is customs available at KNYL for international arrivals?
Yes, CBP inspection services are available onsite at Yuma MCAS / Yuma International, along with a USDA compliance agreement. This joint-use civil/military airport handles international arrivals within its published customs framework rather than requiring a diversion to another port of entry. Crews should note that KNYL sits close to the Mexican border, roughly 7 nautical miles south, and remarks caution against overflight of that boundary due to jet training operations in the vicinity. Coordination with airport operations is advisable given the military traffic sharing the field. Dispatchers should confirm current customs procedures before planning a border-crossing arrival.
What is the longest runway at KNYL and what is its surface?
The longest runway at Yuma MCAS / Yuma International is 03L/21R, a concrete surface measuring 13,300 feet long and 200 feet wide. This is also the maximum paved runway length listed for the airport. A second parallel runway, 03R/21L, offers 9,240 feet on an asphalt-concrete surface. Two shorter crosswind runways, 08/26 and 17/35, provide 6,146 feet and 5,710 feet respectively. Traffic pattern remarks caution that operations on 03L / R and 21L / R overlap with the pattern for 08/26 and 17/35, so crews should stay alert to mixed traffic flows.
Does KNYL see seasonal variation in business aviation traffic?
Yes, business aviation traffic at Yuma MCAS / Yuma International (KNYL) is concentrated in specific months rather than spread evenly across the year. Based on FAA TFMSC data for 2025, bizav operations peak in the winter months, with February at 659 operations and November and December each above 670 operations. Traffic falls to its lowest point in August at 380 operations, with a general summer dip running from May through September. Dispatchers planning winter-season trips into KNYL should expect comparatively busier ramp and pattern conditions than during summer months.
What fuel types are available at Yuma MCAS / Yuma International?
Yuma MCAS / Yuma International (KNYL) lists 100LL, Jet A, and Jet A+ among its fuel types, with Jet A confirmed available. Remarks also reference F-24 military fuel, described as available on request for shipbound aircraft, though this entry pertains to military fuel handling rather than general civil fuel service. Fuel-related remarks note FBO frequency coordination and specific availability windows tied to military operating hours. Civil operators should confirm current fuel service hours directly, since the field operates under joint civil/military scheduling. Attendance at the field is listed as all days, all hours.
How hot does it get at KNYL during summer months, and what does that mean for performance planning?
Yuma MCAS / Yuma International (KNYL) experiences average maximum temperatures near or above 100°F from June through September, with July reaching 106.7°F and August 106.4°F according to the source climate data. July and August also average around 31 and 30.9 days respectively above 90°F, the highest of any months on record. Given the field elevation of 213 feet, these high density-altitude conditions during summer should factor into takeoff and landing performance calculations. Winter months are comparatively mild, with December averaging 67.8°F. Crews planning summer operations into KNYL should account for reduced aircraft performance margins.
