A12468 is requesting clearance from Jackson to Baton Rouge via V245. What are the specified altitudes for this flight?

The specified altitudes for a flight along V245 provide a series of levels that are commonly used for en-route navigation, particularly at higher altitudes. The correct choice lists altitudes starting from 40, and incrementing by 20s up to 160. This altitude clearance is consistent with standard operating procedures for IFR (Instrument Flight Rules) flights to ensure proper vertical separation from other aircraft, particularly for those navigating at higher levels within controlled airspace.

Using a structured altitude assignment like this helps in managing traffic flow effectively along busy airways and provides sufficient altitude separation between ascending and descending aircraft, as well as between aircraft operating on adjacent routes. The inclusion of a wider range of altitudes also makes it easier for controllers to provide flexibility based on traffic conditions, weather patterns, and other operational factors.

In contrast, the other choices provided offer either insufficient or inappropriate altitude assignments for an aircraft operating on a high altitude route like V245, focusing instead on lower altitudes that may not align with typical ATC procedures for longer-range, high-altitude flights.
