Best practices & technologies for successful airport drone detection

The threats posed by drones near airports

Drone activity near airports has become a significant security concern in recent years. As of 2026, the Federal Aviation Administration (FAA) receives around 100 reports of drones flying near airports each month, while illegal drone incursions rose by more than 25% in early 2025.

Whether piloted by hobbyists or organized criminals, unauthorized drone activity near airports can severely impact aviation operations, often leading to financial losses related to unplanned downtime and damage to sensitive aircraft. The threats posed by drones near airports include:

• Operational disruptions: Sightings of drones flying near airports force authorities to suspend operations until the airspace is cleared, leading to flight delays and diversions that can impact hundreds of thousands of people. In 2018, Gatwick Airport was forced to delay 1,000 flights in response to drone activity, at a cost of $64.5 million in lost revenue.
• Damage to aircraft: If a drone comes into contact with an aircraft, whether stationary or in mid-air, it can cause catastrophic structural damage. A 2017 study conducted by the Alliance for System Safety of UAS through Research Excellence found that drone strikes cause more damage to aircraft than collisions with birds of the same mass and velocity.
• Pilot distraction: The presence of drones near airports can distract pilots during takeoff and landing procedures, impacting their ability to control the aircraft safely. In 2019, a drone flew within 20ft of an Airbus A320 as it left Gatwick airport, risking the lives of up to 186 passengers by drawing the pilots’ attention away from mission-critical duties.
• Targeted attacks: Drones can be used as a vehicle to deliver dangerous payloads like explosive or hazardous materials by malicious actors working from remote locations. In 2026, 8 explosive-laden drones were launched at an airport in the Democratic Republic of the Congo, requiring intervention from airport drone detection and response systems.
• Espionage operations: Criminals can attach recording devices like cameras, sensors and microphones to drones and deploy them to collect information unlawfully. This type of airport drone security risk has become more common in recent years, with incidents reported at Bulgaria’s primary international airport and a Belgian military airbase in 2025.

How do airports counter drone activity?

Airports counter drone activity by deploying specialized security technologies to identify unauthorized aircraft in secure airspace. Airport drone detection technologies are the first line of defence in an effective counter-drone strategy as they enable leaders to enact swift, informed responses.

Detection technologies like radars, radio frequency scanners, acoustic sensors and cameras equipped with smart video analytics are used to detect telltale signs of drones near airports. These devices can identify unique stimuli associated with drones like control signals, motor sounds and thermal signatures, then send real-time alerts to operators and engage wider responses.

Should an airport drone detection tool identify suspicious activity, further technological and organizational responses can be enacted. Typical drone mitigation countermeasures include:

• Signal jamming: Electronic devices are used to block communications between the drone and its operator, forcing the craft to either hover and land or return to its home.
• Protocol manipulation: Specialized cyber-takeover software can learn and mimic the control signal of drones near airports, enabling on-site personnel to take full control.
• Geofencing: Some drone manufacturers implement software restrictions that prevent drones from entering restricted airspace; this can help to tackle accidental incursions.
• Physical interception: In situations requiring maximum airport drone security, authorities may use kinetic or energy-based devices to physically neutralize threats.
• Security lockdowns: To help mitigate the impacts of airport drone security incidents, facilities can be locked down and operations suspended until the threat is neutralized.

Understanding airport drone restrictions and regulations

To help combat the rising threat of illegal airport drone activity, state and federal government agencies have published clear guidance intended to limit the operation of unmanned aircraft near air strips, ports and bases; here are some examples of current airport drone restrictions.

General FAA restrictions

In the U.S., the legality of flying drones near airports is dependent on the type of airspace the drone is operating in and whether the operator has received prior authorization from the FAA. 

Official FAA guidance states that ​“Drone operators should avoid flying near airports because it is difficult for manned aircraft to see and avoid a drone while flying,” adding that ​“For flights near airports in controlled airspace, drone operators must receive an airspace authorization”.

Drone operators are advised to use the FAA’s B4UFLY service to check whether the airspace they intend to fly in is controlled or not prior to launch. Registered drone operators can request authorization for controlled zones via a Low Altitude Authorization and Notification Capability (LAANC) service supplier or via the FAADroneZone service for zones not serviced by LAANC.

The FAA Part 107 regulation

In addition to meeting general FAA airport drone requirements, commercial drone pilots must maintain compliance with the FAA Part 107 Regulation for Small Unmanned Aircraft Systems.

In adherence with the Part 107 regulation, drone operators must:

• Maintain a line-of-sight: Pilots must maintain a visual line-of-sight during all daylight flights; flight visibility must be at least 4.8 km from the control station and the minimum distance between the craft and cloud cover must be 2,000 ft horizontally / 500 ft below.
• Leverage anti-collision systems: Flights may only be conducted during twilight and at nighttime if the aircraft has working anti-collision flashing light systems in operation.
• Avoid high-traffic areas: Unmanned craft may not be flown over people or moving vehicles; exceptions can be made for people participating in the operation of the craft.
• Maintain a safe altitude: The altitude of unmanned aircraft may not be higher than 400 ft above ground level unless the craft is flown within a 400 ft radius of a structure and does not fly higher than 400 ft above that structure’s immediate uppermost limit.
• Maintain a safe groundspeed: The groundspeed of small unmanned aircraft may not exceed 87 knots / 100 mph, unless the pilot has obtained a waiver from the FAA.
• Adhere to airspace class rules: Operations are permitted in Class G airspace so long as the operator gives way to crewed aircraft; operations in Class B, C, D and E airspace require prior authorization; class jurisdictions can be identified via B4UFLY.

State and local regulations

Alongside FAA regulations concerning drones and airports, several states and localities have published unique laws intended to further restrict drone operations in high-risk airspace.

Examples of states with area-specific airport drone restrictions include:

• Nevada: Under Nevada state law, a person may not fly a drone within a 5‑mile distance of an airport without prior consent of the airport authority or airport operator.
• Arkansas: Under Arkansas state law, a person may not use a drone to survey or photograph critical infrastructure like airports without prior permission from the FAA.
• Texas: Under Texas state law, a drone’s distance from an airport must be maintained at 5+ miles and the drone may not be used to capture images of critical infrastructure. 

Notable airport drone detection challenges

Even with state and federal regulations severely restricting the use of drones near airports, illegal drone incursions have increased by over 25% in recent times. Numerous factors can make it difficult to reliably detect and tackle drones in controlled airspace, including:

• Small size: It can be difficult to visually and audibly distinguish drones from normal airborne objects like birds and planes due to their small size and lightweight frames.
• Countermeasures: Some drones leverage autonomous flying modes and operate on non-standard radio frequencies to evade detection via jamming/​scanning measures.
• Interference: Technology designed to disrupt drone signals may not always be safe to use on drones near airports, as they could interfere with navigation/​comms systems.
• False positives: Some airport drone detection technologies rely on highly-sensitive sensors to detect small drones, increasing the risk of false positives in busy airspace.
• Flexibility: As airports are not standardized, a tool that works in one facility may not function well elsewhere; effective drone detection tools must be highly customizable.

The best tools for airport drone detection

Airport authorities and facility operators can leverage a variety of specialized airport drone detection technologies to identify and inform responses to illegal drone incursions. As each tool has its own pros and cons, an effective system will typically utilize multiple types of devices.

1. Visual drone detection systems

Visual airport drone detection systems combine high-quality IP cameras with intelligent analytics software and multiple visual sensors to detect the presence of drones in most light conditions; a typical device will leverage visible, thermal and infrared light detection sensors.

Visual detection systems allow operators to determine:

• The general location of a drone.
• The travelling speed of a drone.
• The make/​model of a drone.
• A drone’s direction of travel.

Visual detection systems are typically not able to determine:

• A drone’s distance from an airport.
• The specific location of a drone.
• The altitude of a drone.
• The location of a drone’s operator.

Modern counter-drone tracking cameras can leverage pan, tilt and zoom features to reliably identify drones at long range, provided they have a clear line-of-sight. Devices with analytics and radar integration features can instantly verify aerial objects and, via wider integrations with command and control systems, engage automated incident responses to illegal drone activity.

2. Acoustic drone sensor

Acoustic airport drone detection uses specialized microphones to identify sounds consistent with drone activity. These microphones are configured to detect the unique sound signature of spinning drone propellers and will send real-time alerts to operators in response.

Acoustic technologies allow operators to determine:

• The general location of a drone.
• A drone’s distance from an airport.
• The make/​model of a drone.
• A drone’s direction of travel.

Acoustic solutions are typically not able to determine:

• The specific location of a drone.
• The altitude of a drone.
• The location of a drone’s operator.
• The travelling speed of a drone.

These types of airport drone detection have a shorter detection range than other sensor-based systems and their accuracy can be impacted by ambient noise and adverse weather conditions. As a result, they’re best-used to detect drones near smaller airports and as a secondary form of identification alongside additional drone detection.

3. Radar-based counter-drone systems

Radar-based counter-drone systems detect objects in motion using radio waves. Sensors installed around the airport emit radio waves and receive them as they’re reflected off objects in the air; this reflected data is used to discern key characteristics about unmanned aircraft.

Radar-based airport drone detection systems allow operators to determine:

• A drone’s distance from an airport.
• The specific location of a drone.
• The altitude of a drone.
• The travelling speed of a drone.
• A drone’s direction of travel.

Radar-based drone detection systems are typically not able to determine:

• The general location of a drone.
• The location of a drone’s operator.
• The make/​model of a drone.

In most scenarios, radar-based systems have a longer detection range than acoustic, visual and radio frequency airport drone detection tools, but detection requires a clear line-of-sight and can be impeded by existing structures. While range and accuracy are not impacted by noise, they can be affected by adverse weather, though to a lesser extent than other technologies.

4. Radio frequency detection sensors

Radio frequency detection sensors are able to identify and interpret wireless communication signals sent between unmanned aircraft and the operator’s control station. Via the analysis of drone communications, radio frequency can discern key information about the craft.

Radio frequency-based airport drone detection allows operators to determine:

• A drone’s distance from an airport.
• The specific location of a drone.
• The altitude of a drone.
• The location of a drone’s operator.
• The travelling speed of a drone.
• The make/​model of a drone.
• A drone’s direction of travel.

Radio frequency-based drone detection is typically not able to determine:

• The general location of a drone.

Radio frequency-based systems typically have a longer detection range than acoustic and visual sensors and do not require a direct line-of-sight to identify aircraft. However, structures and terrain can impede operations; not all systems can discern information like the make and model of a drone and sensors can’t detect some modern drones that don’t emit radio signals.

Secure your airspace with intelligent airport drone detection

Illegal drone incursions are a growing and significant issue for U.S. airports, with unmanned aircraft systems having the potential to suspend critical operations and cause harm to people and property. To combat this modern issue, facility operators require specialized airport drone detection, but even with these tools, identifying drones can be uniquely challenging.

An effective airport drone detection tool will leverage multiple types of sensors to accurately identify illegal drone incursions in all light and weather conditions. By prioritising smart, integration-ready airport cameras like drone detection cameras, operators can combine the benefits of multiple types of detection sensors to reliably combat incursions.
