No pattern altitude is published for KFDR; 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 KFDR

Frederick Regional Airport is non towered, so the pattern is self announced on CTAF 123.05. 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 KFDR?

Frederick Regional 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 2,300 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 KFDR have right traffic?

No. All 8 runway ends at Frederick Regional Airport use standard left traffic, so no right pattern is charted here.

What frequency is the pattern on at KFDR?

Frederick Regional Airport is non towered, so pattern position reports go on the CTAF, 123.05. AC 90-66B asks for self announcing on entry and on each leg.

More about KFDR

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.
