Which modes produce the 'Whoop Whoop Pull Up' aural warning?

• A. Mode 1 only
• B. Mode 1 and Mode 2
• C. Mode 4 only
• D. Mode 5 only

Answer: (B)

The warning is tied to terrain-related hazard alerts in GPWS/TAWS. The specific aural “Whoop Whoop Pull Up” is produced when two particular warning modes detect an unsafe situation: one mode monitors an excessive descent rate, indicating you’re losing altitude too quickly toward the terrain; the other monitors terrain closure rate, meaning you’re approaching terrain faster than can be safely avoided. When either condition is met within the alerting window, the system emits the distinctive cadence followed by the instruction to pull up. Other warning modes address different anomalies and don’t trigger this exact aural cue, so they don’t produce the “Whoop Whoop Pull Up.”
