Which class of VDF bearing is accurate within 5 degrees?

Class A

Class B

The correct choice is Class B, which is known for its accuracy within a tolerance of 5 degrees. VDF (Vector Direction Finder) bearings are crucial for navigation and situational awareness in aviation, and each class represents a different level of precision.

Class A bearings offer a higher accuracy level with a smaller tolerance, making them ideal for critical navigational tasks where precision is paramount. Class C and Class D bear different tolerances, with Class D being the least strict in terms of accuracy. Class B's capability to remain within 5 degrees makes it suitable for many operational scenarios where a decent level of precision is maintained without the need for Class A accuracy.

Thus, Class B allows for reliable navigation while balancing the need for accuracy with practical usability in various conditions.
