FROPA stands for?

FROPA stands for?

• A. Frontal passage
• B. Front row of pillars
• C. Frost alert
• D. Front anomaly

Answer: (A)

FROPA is shorthand for a frontal passage—the moment a weather front moves through an area. This matters for flight planning because a front typically brings a wind shift (the direction can change and speed may vary), along with changes in temperature and sometimes precipitation or cloud cover. So when you see FROPA in a briefing, you’re being warned of a weather transition as the front passes. The other phrases don’t fit standard aviation weather terminology—they describe unrelated or non-existent terms—so they aren’t used in the same context.
