Final answer:
Under Part 97, to ensure obstacle clearance during emergencies, a specific minimum safe altitude value is set by aviation regulations, typically 1,000 feet above the highest obstacle within a certain radius.
Step-by-step explanation:
The question pertains to the minimum safe altitude required for obstacle clearance during an emergency, as defined by aviation regulations. Under Part 97 of the Federal Aviation Regulations, a safe altitude is one where the aircraft provides adequate clearance of obstacles. Although the specific value is not stated in the question nor in the provided details, as per the Federal Aviation Regulations (FAR), pilots are generally required to maintain an altitude that allows, at a minimum, 1,000 feet of clearance above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft in designated areas. For other areas specified in FAR 91.119, the minimum altitude for non-congested areas is 500 feet above any person, vessel, vehicle, or structure.
