In Waldron's 13/18 operations, the initial position call is over which landmark?

• A. Yorktown Bridge
• B. Oso River
• C. Padre Island
• D. Goliad

Answer: (A)

In this kind of operation, the initial position call is anchored to a fixed, easily recognizable landmark so every aircraft has a single, verifiable starting point for navigation and timing. Yorktown Bridge is the designated fix for Waldron's 13/18 scenario because it sits on the shore along the planned ingress path and provides a clear, easily identifiable reference that all crews can locate visually or with instruments. From that point, the flight can align on the correct bearing, spacing, and timing for the ensuing legs of the mission. The other landmarks aren’t used as the starting fix because they don’t sit on the prescribed entry corridor or aren’t as readily identifiable from the air, which would complicate coordination and disrupt the planned sequence.
