What is a likely consequence of using charts that do not follow WGS 84?

• A. Increased signal accuracy
• B. Significant errors in positioning
• C. Improved satellite connectivity
• D. Reduction in fuel consumption rates

Answer: (B)

Using charts that do not follow WGS 84 can lead to significant errors in positioning because WGS 84 is a global reference frame for geospatial information that is widely adopted in aviation. This standard provides a consistent frame of reference for navigation and ensures that positioning systems, such as GPS, interpret geospatial data accurately. When charts are based on different datums or coordinate systems, discrepancies can arise that cause navigators to misinterpret their actual position. This misalignment can lead to navigation errors, affecting safety and operational efficiency. In aviation where precision is critical, understanding and utilizing the correct reference system is essential for accurate navigation.
