What is the minimum crossing altitude at DBS VORTAC for a northbound IFR flight on V257?

The minimum crossing altitude at DBS VORTAC for a northbound IFR flight on V257 is 8,600 feet. This altitude is specified in the relevant aeronautical charts and procedures that ensure safe navigation and separation from terrain and other air traffic.

The chosen altitude is determined based on the terrain elevation in the area surrounding the DBS VORTAC, as well as the required obstacle clearance for northbound traffic along that route. In IFR operations, maintaining specific altitudes at designated points is crucial for ensuring safety, especially in areas with significant terrain or airspace complexity.

In this case, 8,600 feet is established as the minimum crossing altitude to provide sufficient vertical clearance and safe passage for aircraft navigating that airway. It is important for pilots to follow these established altitudes to abide by regulations and maintain safety in controlled airspace.
