The accuracy range for VOR (VHF Omnidirectional Range) course alignment is indeed plus/minus 1 degree. This level of precision ensures that pilots can accurately follow their intended flight path, minimizing the potential for navigational errors. VOR is a radio navigation system for aircraft that enables pilots to determine their aircraft's position and stay on course by referring to radio signals emitted from fixed ground stations.

In approach and en route phases of flight, the certainty provided by a plus/minus 1 degree alignment allows for effective navigation, especially when integrated with other navigation systems and procedures. The high degree of accuracy is crucial for maintaining separation from other aircraft and adhering to safe flight paths.

The other ranges suggested in the other choices represent less accuracy, which could lead to navigational issues or misalignments that are not acceptable in the critical phases of flight operation.
