What is the minimum altitude at TROTS intersection on V468 from BTG VORTAC to YKM VORTAC?

The correct answer, 11,500 feet, is the minimum altitude at TROTS intersection on V468 between BTG VORTAC and YKM VORTAC due to the requirements for vertical separation along this segment of the airway. The minimum enroute altitude is established to ensure safe terrain clearance and to provide adequate separation from other air traffic.

This altitude takes into account the surrounding terrain and any obstacles, ensuring that aircraft maintain a safe distance above the ground throughout the airspace. Additionally, this altitude aligns with the established air traffic control (ATC) procedures, which dictate the minimum altitudes for specific routes to enhance safety and efficiency in the airspace system.

The other altitude options are either too low to provide the necessary clearance in that particular section of the airway or exceed typical altitude restrictions without justification for structure or terrain. Such considerations are crucial in ensuring compliance with aviation regulations and ensuring that pilots can safely navigate the airspace.
