What minimum altitude is required to fly over the Cedar Hill TV towers in the congested area south of Dallas Executive (RBD)?

• A. 3,400 feet MSL
• B. 3,549 feet MSL
• C. 3,600 feet MSL
• D. 3,800 feet MSL

Answer: (B)

The key idea is that in congested areas you must stay at least 1,000 feet above the highest obstacle within 2,000 feet of your path. To apply this, identify the top height of the Cedar Hill TV towers. The top of those towers sits around 2,549 feet MSL. Add the required 1,000-foot clearance, giving a minimum altitude of 3,549 feet MSL. That ensures you’re operating at least 1,000 feet above the tallest obstacle in the area, within the 2,000-foot radius.
