Operating constraints
Renton Municipal has published operating constraints in five categories: access, runway notes, noise procedures, environmental and other notes.
The west taxiway is closed to aircraft with a wingspan of 118 feet or greater.
Taxiway B between Taxiway B3 and Taxiway B5 is closed to aircraft with a wingspan of 50 feet or greater.
For clearance delivery when the control tower is closed, contact Seattle Approach.
When the control tower is closed, the RNAV (GPS) Runway 16 approach is the preferred instrument approach procedure.
REIL for Runway 16 and 34, and MIRL for Runway 16/34 along with taxiway lights, are pilot-activated on CTAF. PAPI for Runway 16 and 34 operates continuously.
The approach slope is 13:1 to the displaced threshold due to a 1,323-foot tree located 442 feet left of centerline. It is 17:1 due to a 933-foot tree located 180 feet left of centerline. It is 26:1 due to a 20-foot blast fence located 530 feet from the displaced threshold.
Be alert for Boeing production aircraft being towed across the runway during hours when the control tower is closed.
Runway 34 has a 12-foot blast fence located 155 feet from the end of the runway.
A noise abatement procedure is in effect; contact airport administration.
Numerous flocks of birds are present in the vicinity of the airport and along the Lake Washington shoreline at all times.
AFIS (ADCUS) service is available.
A seaplane base is located at the northwest corner of the airport.
The emergency frequency 121.5 is not monitored at the tower.
During RNT tower hours of operation and VMC weather, RNT tower controls the west channel over the water below 800 feet AGL. When operating in the west channel above 800 feet AGL, or when the RNT tower is closed, contact Boeing tower on frequency 118.3 prior to operating in the west channel.

Frequently asked questions
Is customs available at KRNT?
Yes, CBP inspection services are available onsite at Renton Municipal Airport. The airport is listed with an AFIS (ADCUS) facility, which supports advance notice of customs arrivals. This makes KRNT usable for international arrivals without diverting to a nearby customs facility. Flight crews should still coordinate arrival details through the appropriate advance notice channel before landing. Fuel available onsite includes 100LL, Jet A, and Jet A+, supporting a range of arriving aircraft types.
What is the runway configuration at Renton Municipal Airport?
Renton Municipal Airport (KRNT) has a single paved runway, 16/34, measuring 5,382 feet long and 200 feet wide with an asphalt-concrete surface. This is the only runway serving the field, so all arriving and departing traffic uses this strip regardless of wind or approach direction. The runway length aligns with the airport's listed maximum paved distance of 5,382 feet. Operators should factor in the published approach slope restrictions on both ends when planning arrivals, since obstacles reduce the effective glidepath in places.
Are there wingspan restrictions on taxiways at KRNT?
Yes, Renton Municipal Airport has two taxiway wingspan limits published in its remarks. The west taxiway is closed to aircraft with a wingspan of 118 feet or greater. Separately, the section of Taxiway B between Taxiway B3 and Taxiway B5 is closed to aircraft with a wingspan of 50 feet or greater. Operators of larger business jets or transport-category aircraft should confirm routing with ground control before taxi at KRNT to avoid these restricted segments.
What obstacles affect the approach at KRNT?
Renton Municipal Airport publishes several approach slope restrictions tied to trees and a blast fence near the runway. One slope is 13:1 to the displaced threshold due to a 1,323-foot tree positioned 442 feet left of centerline. A second slope of 17:1 applies due to a 933-foot tree 180 feet left of centerline. A third, shallower slope of 26:1 results from a 20-foot blast fence located 530 feet from the displaced threshold. These figures indicate reduced obstacle clearance margins that crews should review before flying the approach at KRNT.
How does Renton Municipal Airport coordinate with nearby Boeing Field traffic?
Renton Municipal Airport, identified by the ICAO code KRNT, sits close to Boeing Field / King County International, about 4.14 nautical miles away, and shares airspace procedures tied to Boeing tower operations. During tower hours and VMC, RNT tower controls the west channel airspace over the water below 800 feet AGL. Operations in that channel above 800 feet AGL, or when the RNT tower is closed, require contact with Boeing tower on frequency 118.3 before entering. Pilots should also watch for Boeing production aircraft being towed across the runway when the KRNT tower is closed.
