If cleared for a straight-in LOC approach from over OALDY, what does this mean for the flight?

When cleared for a straight-in LOC (Localizer) approach from the designated waypoint OALDY, the flight is authorized to proceed directly to the final approach segment of the approach. This means that the aircraft can transition straight to the landing phase without having to conduct a procedure turn, which is typically required only if the approach clearance is for a circle-to-land or requires a change of direction that cannot be achieved on the final approach course.

Being on a straight-in approach allows the pilot to descend to the prescribed altitudes and follow the standard glide path down to the runway, effectively streamlining the approach and landing process. The clearance specifically indicates that the pilot is set to align directly with the runway through the approach as designed, maintaining a safe and efficient descent for landing.
