How can you verify coordinate data for an LZ/PZ?

• A. Rely on memory only.
• B. Compare map coordinates with GPS, confirm with ground unit references, and cross-check with terrain cues.
• C. Use weather reports as the sole verification.
• D. Verify by placing flags at locations.

Answer: (B)

Cross-checking coordinates with multiple independent sources is how you reliably verify an LZ/PZ location. Start with what the map shows and compare those coordinates to what the GPS reads; then confirm those numbers with ground unit references who have up-to-date, on-the-ground familiarity with the area. Finally, match the described location to recognizable terrain features you can see or confirm from the air—things like ridgelines, rivers, roads, and distinctive vegetation patterns. This layered verification helps catch errors from datum differences, GPS drift, or misinterpretation of the map, and it keeps the landing or pickup zones aligned with reality. Relying on memory isn’t reliable for precise coordinates, weather reports don’t verify location, and using flags alone is marking, not validating coordinate data.
