Pattern direction by runway
| Runway | Pattern | Heading | Pattern altitude |
|---|---|---|---|
| 03 | Right traffic | 034° mag | 1,600 ft MSL (≈1,000 AGL) |
| 21 | Left traffic | 214° mag | 1,600 ft MSL (≈1,000 AGL) |
No pattern altitude is published for 12N; 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 12N
Aeroflex/Andover 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: 03. 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 12N?
Aeroflex/Andover 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 12N have right traffic?
Yes, on one runway end: 03. Every other end at Aeroflex/Andover is standard left traffic.
What frequency is the pattern on at 12N?
Aeroflex/Andover 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.
