On 1 March your 2135 zone time DR position is LAT 23°54.0' N, LONG 63°22.0' W. At that time, you observe Schedar bearing 328°psc. The chronometer reads 01h 35m 16s, and the chronometer error is 00m 07s slow. The variation is 3.5°E. What is the deviation of the standard compass?

Correct Answer: Option D — 3.2°W

Navigational reduction of Schedar yields true bearing via the PZX triangle. Comparing true azimuth with standard compass bearing establishes magnetic heading. Applying charted variation isolates the compass deviation of 3.2°W per standard celestial navigation protocols.
