Predictive windshear advisories are available from _________ to __________ AGL.

Predictive windshear advisories are available from _________ to __________ AGL.

• A. 1000';40'
• B. 1200';50'
• C. 1500';60'
• D. 2000';100'

Answer: (B)

Predictive windshear advisories are issued within a defined altitude band so the system can provide timely, relevant warnings across flight phases. For the A320, this window runs from about 1,200 ft AGL up to about 50,000 ft AGL. The lower limit of 1,200 ft gives sufficient lead time for approach and climb phases with reliable predictions, while the upper limit of 50,000 ft keeps alerts within the typical cruise envelope where windshear risk is still meaningful. Ranges that start lower or extend much higher aren’t aligned with the system’s calibrated coverage.
