Aircraft altitude is established by Federal law. Title 14, Code of Federal Regulations Section 91.119 which governs flight states:
“Except when necessary for takeoff of landing, no person may operate an aircraft below the following altitude:
Over any congested area of a city, town or settlement, or over any open-air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.”
It is important to be aware of two aspects of this regulation. First, most aircraft operating near the Boca Raton Airport are in the process of landing or taking off, thus this regulation does not apply. Second, helicopters are specifically exempted from this Federal regulation.
