Aviation and Airport Security Practice Test 2025 – All-in-One Guide for Exam Success!

The Air Commerce Act was enacted in 1926. This act was the first federal legislation to regulate civil aviation in the United States. Option B (1938) is incorrect because it refers to the Civil Aeronautics Act, which was passed in 1938 and replaced the Air Commerce Act. Options C (1978) and D (1985) are also incorrect as they are years much later than 1926 and do not align with the timing of the Air Commerce Act. Therefore, A (1926) is the correct answer as it is the closest and earliest year to when the Air Commerce Act was enacted.
