Pattern direction by runway

Runway	Pattern	Heading	Pattern altitude
13	Right traffic	127° mag	2,000 ft MSL (≈1,000 AGL)
31	Left traffic	307° mag	2,000 ft MSL (≈1,000 AGL)
17	Right traffic	176° mag	2,000 ft MSL (≈1,000 AGL)

No pattern altitude is published for KOWI; the figure above is the AC 90-66B 1,000 ft AGL convention for propeller aircraft, rounded to the field. Turbine aircraft normally fly 1,500 ft AGL. Headings are the runway alignment; downwind is the reciprocal.

Flying the pattern at KOWI

Ottawa Municipal Airport is non towered, so the pattern is self announced on CTAF 122.8. AC 90-66B asks for a report on entry and on each leg, and for the standard 45° entry to downwind at pattern altitude.

Watch the right traffic ends here: 13, 17. A right pattern at a field where the other end is left is the single most common place to end up pointing at opposing traffic. The full entry procedure is here →

Frequently asked

What is the traffic pattern altitude at KOWI?

Ottawa Municipal Airport has no traffic pattern altitude published in the FAA NASR data. The AC 90-66B convention for propeller aircraft is 1,000 ft AGL, which works out to roughly 2,000 ft MSL (≈1,000 AGL) here — but confirm it against the Chart Supplement before you fly, since a field can have a non standard pattern altitude that NASR does not carry.

Does KOWI have right traffic?

Yes, on 2 runway ends: 13, 17. Every other end at Ottawa Municipal Airport is standard left traffic.

What frequency is the pattern on at KOWI?

Ottawa Municipal Airport is non towered, so pattern position reports go on the CTAF, 122.8. AC 90-66B asks for self announcing on entry and on each leg.

Pattern direction and alignment are drawn from the FAA NASR (28-day cycle); the diagram is generated, not an FAA chart. Pattern altitude is shown as published where NASR carries one, otherwise as the AC 90-66B 1,000 ft AGL convention. For planning and education only; always verify against the Chart Supplement.
