What does TACAN provide in addition to azimuth information?

TACAN, which stands for Tactical Air Navigation, is a system used primarily by military aircraft to determine their position relative to a ground station. In addition to providing azimuth information, TACAN also transmits an identity signal that includes the station information using Morse Code. This identification (ID) allows pilots to verify which TACAN station they are receiving signals from, enhancing situational awareness during navigation. This is crucial for ensuring accurate course tracking and confirmation of location, especially in areas where multiple navigation aids may be present.

While the other choices may pertain to various aspects of navigation and flight operations, they do not accurately describe the functions of TACAN. It does not provide vertical guidance, correct flight paths, or weather updates, making identification via Morse Code the correct additional information provided by the TACAN system.
