A A
B B
C C
D D
AI Explanation

The correct answer is O. The major limitation in using the Sight Reduction Tables for Air Navigation Volume I (Pub. No. 249) is that they are not intended for use in maritime navigation. The Sight Reduction Tables are designed specifically for air navigation, where the observer's height above the Earth's surface is significantly greater than in maritime applications. As a result, the assumptions and methods used in the tables are not directly applicable to sea-level navigation, which requires different approaches and considerations. The other answer choices (A, B, C, D) do not accurately describe the major limitation of using the Sight Reduction Tables for Air Navigation Volume I in the context of US Coast Guard Captain's License Examinations, which are focused on maritime navigation.
