N281, a Piper Apache, is requesting clearance from Jackson to Greenville via V74. What are the correct altitudes for this flight?

For the flight of N281, a Piper Apache, requesting clearance via V74, the correct altitudes are related to the FAA's guidelines for en-route aviation under Instrument Flight Rules (IFR). The altitudes provided for VFR (Visual Flight Rules) routes will differ from those for IFR, which are structured based on the east or west of the airway, and they follow a systematic allocation of altitudes to ensure safe vertical separation between aircraft.

The correct altitudes consist of those that ensure proper altitude assignment for IFR traffic, typically in increments of 20,000 feet, such as 40, 60, 80, and upwards to 100, 120, and 140. These altitudes facilitate compliance with regulations that designate specific altitude ranges for aircraft based on the route they fly and the direction of flight. This designated altitude structure not only supports traffic management at critical sections of airspace but also enhances safety by maintaining proper vertical separation between flights.

Therefore, the set of altitudes including 40, 60, 80, 100, 120, and 140 aligns with those critical safety and regulation measures that govern IFR flight operations, making this selection appropriate for N281’s requested routing via V74.
