When comparing wind-direction indicators, what degree difference defines out-of-tolerance?

Explanation:
Two wind-direction indicators must agree closely to give accurate wind information for safe ATC operations. The allowable difference between two indicators is five degrees. So, readings that differ by more than five degrees are out of tolerance, signaling a need for inspection or recalibration. A three- or four-degree discrepancy stays within the acceptable range, while a six-degree difference would exceed the limit and be considered out of tolerance.
