Pattern direction by runway
| Runway | Pattern | Heading | Pattern altitude |
|---|---|---|---|
| 09 | Left traffic | 090° mag | 1,600 ft MSL (≈1,000 AGL) |
| 27 | Left traffic | 270° mag | 1,600 ft MSL (≈1,000 AGL) |
No pattern altitude is published for M71; 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 M71
Greensfield 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 →
Frequently asked
What is the traffic pattern altitude at M71?
Greensfield 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 1,600 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 M71 have right traffic?
No. All 2 runway ends at Greensfield use standard left traffic, so no right pattern is charted here.
What frequency is the pattern on at M71?
Greensfield is non towered, so pattern position reports go on the CTAF, 122.9. AC 90-66B asks for self announcing on entry and on each leg.
More about M71
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.
