About Karl Stefan Memorial Airport

Overview

Karl Stefan Memorial Airport serves Norfolk, Nebraska, functioning as a medium-sized airport located in the north-central part of the state. Situated at 1,573 feet above mean sea level, the airport provides critical aviation infrastructure for the surrounding region, with two parallel asphalt runways each measuring 5,800 feet in length.

Flying Conditions

Weather conditions at KOFK demonstrate predominantly favorable flying environments, with 73.5% of observations reporting Visual Flight Rules (VFR) conditions. The airport experiences significant seasonal temperature variations, ranging from -23°C to 33°C, with September, October, and January offering the most consistent VFR conditions. Winds predominantly originate from the south at an average speed of 9.9 knots, with occasional gusts up to 35 knots.

Notable Features

Both runways (01/19 and 14/32) offer excellent wind alignment, with 100% favorable wind coverage. The airport's geographic positioning and runway configuration provide flexibility for pilots during various wind conditions, with average crosswinds of 5.9 knots on runway 01/19 and 4.2 knots on runway 14/32. Visibility averages 9.3 statute miles, with minimal instances of restricted visibility.

Approach Considerations

Pilots can expect reliable approach conditions, with only 6.2% of observations reporting Instrument Flight Rules (IFR) and a low 4.3% reporting Low IFR conditions. The consistent southerly winds suggest runway 01/19 and 14/32 will typically provide straightforward approach and landing scenarios. Calm wind conditions occur approximately 9.5% of the time, further enhancing operational predictability.
