Bearing Error is specified as a standard value of how many degrees?

• A. 2 degrees
• B. 4 degrees
• C. 6 degrees
• D. 8 degrees

Answer: (B)

Bearings have a built-in tolerance due to instrument limits, alignment, and human reading error. The standard tolerance used in these practice scenarios is plus or minus 4 degrees, so a bearing is considered accurate within 4 degrees. That makes four degrees the best choice because it reflects typical instrument accuracy and gives a consistent basis for plotting and corrections. A smaller tolerance like 2 degrees would be unrealistically strict for everyday readings, while larger tolerances such as 6 or 8 degrees would introduce too much uncertainty for standard navigation calculations.
