Frequently asked questions
What runways are available at KCMI?
University of Illinois / Willard Airport operates three paved runways. The primary runway, 14L/32R, measures 8,101 feet long and 150 feet wide, surfaced in asphalt-concrete. Runway 04/22 offers 6,502 feet of length at the same 150-foot width, also asphalt. A shorter crosswind runway, 14R/32L, runs 3,816 feet by 75 feet, but it carries restrictions on larger commercial operations and closes to aircraft above 12,500 pounds during certain hours. Dispatchers planning for larger aircraft should default to 14L/32R or 04/22.
Does KCMI have customs and border clearance capability?
Yes, University of Illinois / Willard Airport maintains customs capability onsite. CBP inspection services are available, and the airport also holds a USDA compliance agreement covering agricultural inspection requirements. This combination supports international arrivals without requiring a diversion to another port of entry. Crews should still confirm current staffing and any advance notice requirements directly with CBP before planning an international leg into KCMI, since availability details beyond the compliance agreement itself are not part of this record.
Are there weight or aircraft restrictions on any runway at KCMI?
Yes, restrictions apply mainly to runway 14R/32L at University of Illinois / Willard Airport. That runway is not available for Part 121 or Part 380 scheduled passenger operations exceeding nine passenger seats, or non-scheduled passenger operations exceeding 30 passenger seats. It also closes between 2300 and 0600 local, and it is closed to aircraft above 12,500 pounds. Separately, taxiways E and D southwest of runway 14L/32R are closed to aircraft above 11,800 pounds. Operators of larger aircraft should route through 14L/32R or 04/22 and avoid the restricted taxiway segment.
What airport lighting is available at KCMI when the tower is closed?
When the control tower at University of Illinois / Willard Airport is closed, pilots activate lighting themselves over CTAF. This includes the MALSR on runway 32R, PAPI on runway 14L/32R, MIRL on runway 04/22, and HIRL on runway 14L/32R. The HIRL system on 14L/32R defaults to low intensity and must be increased manually via CTAF if higher intensity is needed. Runway 32R also serves as the designated calm-wind runway whenever the tower is closed.
Is business aviation traffic at KCMI concentrated in certain months?
Yes, business aviation traffic at University of Illinois / Willard Airport shows a clear seasonal pattern based on FAA TFMSC data for 2025. Monthly operations climb through the year, starting near 257 in January and rising to a peak of 462 in October, with September and November also running high near 435 and 414 respectively. Winter months from December through February sit lowest, in the 257 to 304 range. Dispatchers scheduling around the airport's total annual bizav volume of 4,202 operations should expect the fall period to carry the heaviest load.
