Dyess Air Force Base traffic pattern

Pattern altitude at Dyess Air Force Base (DYS · KDYS) is 2,800 ft MSL (≈1,000 AGL) by the standard convention — none is published for this field, and every runway end is standard left traffic.

No pattern altitude is published for KDYS; 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 KDYS

Dyess Air Force Base is towered, working 133.0. Contact the tower before entering the surface area and fly the pattern you are assigned — the directions below are the charted default when no instruction is given.

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 KDYS?

Dyess Air Force Base 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 2,800 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 KDYS have right traffic?

No. All 6 runway ends at Dyess Air Force Base use standard left traffic, so no right pattern is charted here.

Do I fly a standard pattern at KDYS?

Dyess Air Force Base is towered (133.0), so the pattern shown here is the charted default — but the controller's instruction overrides it. Expect straight in approaches, base entries and midfield crossings as traffic dictates.

More about KDYS

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.
