What maximum elevation would assure obstruction clearance during a flight from Hicks Airport to Northwest Airport?

The correct maximum elevation ensuring obstruction clearance during the flight from Hicks Airport to Northwest Airport is 3,200 feet MSL. This altitude is determined by considering the highest terrain and obstacles along the route, adding a buffer for safety.

When calculating maximum elevation for safe navigation, it's crucial to account for the highest obstruction in the area plus a margin defined by regulations, typically 1,000 feet above the highest obstacle in mountainous terrain and 500 feet in non-mountainous areas. In this scenario, a maximum elevation of 3,200 feet MSL adequately represents a buffer that accommodates any high terrain or obstacles that may exist between the two airports, ensuring vertical clearance during the flight, even in potentially variable weather conditions or navigation uncertainties.

This altitude also takes into account standard recommended altitudes for en route navigation in relation to the airspace structure and ensures compliance with relevant Federal Aviation Administration (FAA) regulations, which helps avoid potential hazards during the flight.
