Aircraft operations and noise standards in Delaware are governed by federal law under the FAA, which preempts state and municipal regulation of flight paths, altitudes, and in-air noise levels, leaving Delaware airports limited ground-based authority only.
The federal Airline Deregulation Act and Federal Aviation Act preempt state and local regulation of aircraft noise, flight operations, and airspace. Delaware municipalities cannot impose curfews, altitude limits, or noise caps on aircraft in flight. The FAA Part 150 noise compatibility program governs airport noise mapping at facilities such as Wilmington Airport and Dover AFB. Delaware's Department of Transportation Office of Aeronautics coordinates with the FAA but cannot independently restrict overflights. Airport proprietors may impose limited operational restrictions on ground operations, runway use, and based aircraft if reasonable and nondiscriminatory.
Federal violations are enforced by the FAA, with civil penalties up to $1,644 per violation for individuals and substantially higher for commercial operators under 14 CFR enforcement.
