What are the approved pattern entries for RWY 28L/R from Southwest, Sand Springs, Owasso, and Chandler?

• A. Left base; Left downwind
• B. Left downwind
• C. Right base; Right downwind
• D. Straight-in

Answer: (B)

When you join a traffic pattern, you have to enter on a leg that matches the airport’s published pattern direction. For Runways 28L and 28R, the standard pattern is left-hand traffic. From the west-side locations mentioned, the safest and most straightforward way to join is on the left downwind leg. That puts you flying parallel to the runway in the correct direction for a left-hand pattern, after which you’ll turn onto the base and then final with left turns.

Entering on base or straight-in would imply a different sequence and isn’t the standard way to join from those positions unless you’re specifically cleared for it. A right-hand entry would contradict the published left-hand pattern, so it’s not appropriate here. This is why left downwind is the best, correct choice.
