Final answer:
The accuracy of VOR course alignment is generally within ±1 degree, providing precision in aviation navigation.
Step-by-step explanation:
The accuracy of course alignment of the Very High-Frequency Omnidirectional Range (VOR) system is known for its precision in aviation navigation. When discussing the accuracy of VOR, it is typically referred to being within ±1 degree. Therefore, the correct answer to your question is: A) 1 degree.
This high level of accuracy ensures that aircraft can safely navigate and maintain their intended flight paths, which is essential for avoiding airspace conflicts and ensuring timely arrivals.
