What runway options are available at KRRL for business aircraft?
KRRL offers two paved asphalt runways: 07/25 at 5,101 feet by 75 feet, and 16/34 at 2,997 feet by 75 feet. The longer 07/25 runway is the primary option for business turboprops and light jets given its greater length. Both runways are paved, and lighting is available via pilot-controlled MIRL on the CTAF frequency.
Is fuel available at Merrill Municipal Airport outside staffed hours?
Fuel is available 24 hours a day at KRRL through a credit card self-service system, according to airport remarks. Both 100LL and Jet A (A+) grades are offered. This allows aircraft to refuel outside the posted attendance schedule of Monday through Saturday, 0800 to 1700 local.
How far is customs clearance from KRRL?
KRRL does not have onsite customs service; the nearest customs facility is at Appleton (KATW), approximately 76 nautical miles away. Operators arriving from international destinations need to plan a stop at KATW or another customs-equipped airport before or after using Merrill Municipal Airport. No customs processing is available directly at the field.
What operational hazards should pilots be aware of at KRRL?
Merrill Municipal Airport reports ultralight aircraft activity on and in the vicinity of the airport, which pilots should watch for during arrival and departure. A turf area is also available for aircraft operations along the runway safety area north of where the 07/25 pavement ends, marked with white markers, but this surface is used at the pilot's own risk.
