What is the minimum altitude for crossing Gymme intersection en route on V112 from BTG VORTAC to LTJ VORTAC?

The minimum altitude for crossing Gymme intersection en route on V112 from BTG VORTAC to LTJ VORTAC is determined based on established Minimum en route Altitudes (MEA) relevant to the specific route and airspace. The MEA ensures that aircraft maintain a safe altitude that accommodates terrain clearance and guarantees reception of navigational signals.

In this case, the correct altitude of 7,000 feet incorporates necessary safety factors, including the elevation of surrounding terrain and airspace requirements in that section of V112. When navigating through this airway, pilots must adhere to the MEA to ensure safe operations, avoiding obstacles while ensuring compliance with air traffic control regulations.

The incorrect choices do not meet the requisite altitude criteria set for this route. Altitudes lower than 7,000 feet may not provide adequate clearance for the terrain or might compromise navigational signal integrity, which are critical for safe flight operations along an airway.
