What are the correct altitudes for a flight from Jackson to Baton Rouge via V245?

The correct altitudes for a flight from Jackson to Baton Rouge via V245 are indeed represented in the second choice. The V245 airway has specific altitude assignments that align with standard levels for en-route air traffic management.

Typically, air traffic control segments airspace into altitude levels to enhance safety and efficiency for aircraft separation and navigation. The altitudes listed in the correct choice, which include a continuous sequence of even thousands from 40,000 feet up to 16,000 feet, also accommodate the requirements for aircraft operating within specific confines of airspace regulations and are ideal for high altitude flight along airways.

Other choices present altitudes that do not generally correspond to regulated altitudes for that specific airway or may jump in sequences that are not typical for continuous en-route management. For instance, the first choice does not provide a comprehensive range, as altitudes often run in increments of 2,000 feet (like 40, 60, etc., in B). Each of the incorrect options fails to meet either the continuity or the altitude criteria set for V245, as established by the aviation authorities.
