Final answer:
FAA regulations require a minimum altitude of 1,000 feet above any obstacles within a congested area, thus a pilot would need to fly at least 1,000 feet above the tallest TV tower southwest of Savannah Hilton Head International.
Step-by-step explanation:
The minimum altitude required for flying over obstacles such as TV towers in a congested area is not directly provided in the given question reference material. However, based on FAA regulations, an aircraft must maintain a minimum altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft when flying over a congested area. Additionally, commercial aircraft must maintain a separation of five miles horizontally or 2,000 feet vertically from another aircraft, or 1,000 feet if below 29,000 feet in altitude.
Applying these general rules to the scenario of flying over the TV towers southwest of Savannah Hilton Head International (SAV), a pilot would have to determine the height of the tallest TV tower in that area and then ensure they are at least 1,000 feet above it within the specified horizontal radius. This means if the highest TV tower is, for example, 1,500 feet tall, the minimum altitude for safe, regulatory-compliant flight would be at least 2,500 feet above ground level in the immediate area of the TV tower to satisfy FAA regulations.
