What term is included in ATIS following wind shear advisories and remains in effect until 20 minutes after the last report?

• A. "LOW LEVEL WIND SHEAR ADVISORIES IN EFFECT"
• B. "WIND SHEAR WARNING IN EFFECT"
• C. "WIND SHEAR ADVISORY ENDS"
• D. "WIND SHEAR REPORTS ARE CURRENT"

Answer: (A)

ATIS communicates ongoing hazards so pilots know what to expect during approach and departure. When wind shear conditions are present but not at the level of a warning, the operational notice used is that low level wind shear advisories are in effect. This wording signals that the hazard is active at low altitudes and pilots should plan accordingly for possible abrupt changes in wind near the surface.

The reason this phrase stays in the ATIS for 20 minutes after the last report is to cover the potential persistence of wind-shear effects even after reports cease. Wind shear conditions can linger or reoccur, so keeping the advisory in the information broadcast ensures pilots still have up-to-date hazard information through the final stages of flight.

Other options describe different states: a wind shear warning would indicate a more severe, currently observed hazard, which is not what’s being described here; wording that the advisory ends or that reports are current would not convey a continuing advisory status.
