No pattern altitude is published for KGTB; 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 KGTB

Wheeler Sack Army Air Field is towered, working 118.75. 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.

Watch the right traffic ends here: 21, 08, 15. 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 KGTB?

Wheeler Sack Army Air Field 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 1,700 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 KGTB have right traffic?

Yes, on 3 runway ends: 21, 08, 15. Every other end at Wheeler Sack Army Air Field is standard left traffic.

Do I fly a standard pattern at KGTB?

Wheeler Sack Army Air Field is towered (118.75), 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 KGTB

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.
