Pattern altitude is published for H37 in the FAA NASR data. Headings are the runway alignment; downwind is the reciprocal.

Flying the pattern at H37

Herlong is non towered, so the pattern is self announced on CTAF 122.9. AC 90-66B asks for a report on entry and on each leg, and for the standard 45° entry to downwind at pattern altitude.

All ends are left traffic, which is the FAR 91.126 default — turns to the left unless the field charts otherwise. The full entry procedure is here →

More about H37

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.
