The use of drones has become increasingly popular over the years, with many enthusiasts and professionals alike taking to the skies to capture stunning footage or conduct aerial surveys. However, there are rules and regulations that govern the operation of drones, and one of the most critical aspects is altitude. The general rule of thumb is to keep your drone below 400 feet above ground level (AGL). But what happens if you fly a drone higher than 400 feet? In this article, we’ll delve into the consequences of flying above the recommended altitude and explore the reasons behind this restriction.
Why is 400 Feet the Magic Number?
The 400-foot limit is a guideline set by the Federal Aviation Administration (FAA) in the United States, as well as by aviation authorities in many other countries around the world. This altitude limit is in place to ensure safe operation of drones and to prevent conflicts with other aircraft, such as helicopters, airplanes, and gliders.
The primary reason for this limit is to avoid collisions with manned aircraft. At higher altitudes, the risk of collision increases significantly, as drones may enter the flight paths of other aircraft, potentially causing catastrophic consequences. Additionally, flying above 400 feet can make it challenging for drone pilots to maintain visual line of sight with their aircraft, increasing the likelihood of losing control or encountering other hazards.
Legal Consequences of Flying Above 400 Feet
Flying a drone above 400 feet without proper authorization or in violation of regulations can result in legal consequences. In the United States, for example, the FAA can impose penalties, fines, and even criminal charges on drone pilots who recklessly operate their aircraft.
Violations of drone regulations can lead to:
- Civil penalties of up to $27,500 per violation
- Criminal penalties, including fines and imprisonment
- Revocation of drone certifications or licenses
- Confiscation of the drone and other equipment
In addition to these legal consequences, flying above 400 feet can also lead to insurance issues. Many drone insurance policies have altitude restrictions, and flying above 400 feet may void the policy or limit coverage in the event of an accident.
