Both runways support the airport's maximum paved length of 6,001 feet.
Is KOTM a towered airport, and how are arrivals coordinated?
KOTM, Ottumwa Regional Airport, is a non-towered field. Remote control aircraft operations occur in the area, so pilots should monitor CTAF closely for local traffic. For clearance delivery, if a pilot is unable to contact the appropriate frequency through FSS, the remark instructs contacting Chicago ARTCC instead. This backup procedure is specific to KOTM's operating environment and should be part of any arrival briefing. Lighting systems including MALSR, REIL, PAPI, and HIRL are all activated via CTAF rather than tower control.
What fuel is available at Ottumwa Regional Airport?
Ottumwa Regional Airport, KOTM, offers both 100LL and Jet A fuel. The field operates on an attendance schedule of 0700 to 2000 local time, every day of the week. Business aviation traffic at KOTM totaled 545 operations in 2025 according to FAA TFMSC data, out of 806 annual operations overall. Crews should plan fuel stops within the posted attendance hours since the schedule is not 24 hours.
Does traffic at KOTM vary by season?
Yes, business aviation traffic at Ottumwa Regional Airport shows notable month-to-month variation. April recorded the highest monthly figure at 85 operations in 2025, according to FAA TFMSC data, while February was the lowest at 18 operations. Several months in the fall, including October and November, also showed elevated activity above 50 operations each. Dispatchers scheduling flights through KOTM should account for this uneven distribution rather than assuming a flat monthly average.
