What You'll Learn
Authorization to fly near airports
Controlled airspace
If you plan to fly a drone in controlled airspace, you need authorization. Controlled airspace includes Class B, C, D, and E airspace.
- Class B airspace surrounds the nation's busiest airports and extends from the surface to 10,000 feet above mean sea level (MSL).
- Class C airspace surrounds airports with operational control towers, radar approach control, and a certain number of instrument flight rules (IFR) operations or passenger enplanements. It extends from the surface to 4,000 feet above the airport elevation (AGL).
- Class D airspace typically includes small city airports with control towers.
- Class E airspace has varying lower limits, including the surface, 700 feet AGL, 1,200 feet AGL, or 14,500 feet MSL in sparsely populated areas. Its upper limit is up to but not including 18,000 feet MSL.
To obtain authorization for controlled airspace, drone pilots can use the Low-Altitude Authorization and Notification Capability (LAANC) program, which provides near-instant authorization through mobile or web applications. As of 2021, LAANC is available at over 700 airports across the US. Alternatively, you can request authorization manually through the Federal Aviation Administration (FAA) Drone Zone online.
Uncontrolled airspace
In uncontrolled airspace, prior authorization is generally not required for flights below 400 feet above the ground. However, drone pilots must remain aware of and avoid traffic patterns, takeoff and landing areas, and yield the right-of-way to other aircraft. Additionally, drones must not interfere with airport operations.
Special cases
Public entities, such as law enforcement or government agencies, may receive special permission from the FAA to fly in designated locations near airports.
Transport Canada also has established procedures for drone operations within certain distances of aerodromes, with specific requirements for lower-risk beyond visual line-of-sight (BVLOS) operations.

Airspace restrictions and guidelines
Controlled and Uncontrolled Airspace
Drone operators should understand the difference between controlled and uncontrolled airspace. Controlled airspace is typically found around airports and at certain altitudes where air traffic controllers actively manage all air traffic. In contrast, uncontrolled airspace refers to areas where air traffic controllers are not directing air traffic within its limits. In general, drone pilots can fly in uncontrolled airspace below 400 feet above the ground without prior authorization. However, it is important to remain vigilant and avoid interfering with airport operations and aircraft traffic patterns.
Authorization Requirements
Prior authorization is required for flying in controlled airspace near airports. This authorization can be obtained through the Low Altitude Authorization and Notification Capability (LAANC) system or manually via the FAA Drone Zone online platform. Part 107 remote pilots and recreational flyers can also use a LAANC service supplier to obtain authorization for altitudes below the posted UAS Facility Map grid altitudes. Additionally, drone pilots must have a means of communication with the airspace authority during their operation.
Airport Classification
Airports are classified based on air traffic and infrastructure. Large airports with the highest traffic typically fall under Class B airspace, which is the most restrictive for low-altitude manned aviation. Medium-sized airports are usually classified as Class C or D and often accommodate flight schools and general aviation traffic. These classifications help determine the required authorizations and restrictions for drone operations near these airports.
Risk Mitigation
When operating near any airport, it is crucial to follow safety guidelines to mitigate risks. Drone pilots should listen for aircraft noise, scan the sky for potential conflicts, and be prepared to pause the mission if necessary. A visual observer can assist in monitoring the drone and surrounding airspace. Operations near runways and within 2 miles of the ends of runways are particularly risky and require caution. Additionally, always give way to other aircraft and avoid interfering with their operations.
Country-Specific Regulations
Drone regulations can vary by country. In Canada, drone pilots must request flight authorization from aerodrome authorities and comply with restrictions outlined in the Canada Flight Supplement or the NRC Drone Site Selection Tool. In the United States, the Federal Aviation Administration (FAA) manages most of the airspace and enforces specific guidelines, such as registration requirements, visual line-of-sight restrictions, and prohibitions on flying over people or large crowds. Always refer to the regulations of the country in which you are operating your drone.

Safety precautions and risks
Drone flights near airports are prohibited by the Federal Aviation Administration (FAA) because they can pose safety risks to other aircraft and disrupt air traffic control. Drone operators must avoid manned aircraft and are responsible for any safety hazards their drone creates in an airport environment. Drone operators should avoid flying near airports because it is difficult for manned aircraft to see and avoid a drone while flying.
Before flying a drone, operators must conduct a survey of the area and consult Notice to Airmen (NOTAMs) for the flight location. NOTAMs tell pilots about events and obstacles that may affect them, and include the time and location of the event. Drone pilots must also have a means to contact, and be contacted by, the airspace authority during their operation.
For flight near airports in controlled airspace, drone operators must receive airspace authorization prior to operation. Airspace authorizations come with altitude limitations and may include other operational provisions. Controlled airspace and other flying restrictions can be found on the FAA's B4UFLY app.
Operations off the ends of runways (within 2 miles) are the riskiest because of the mix of aircraft at these airports. This includes student pilots, hobbyists, airline pilots, and helicopter pilots, who tend to operate at lower altitudes and can be unpredictable. To mitigate risk, drone operators should listen for aircraft noise, scan the sky, and use a visual observer to keep an eye on the drone and scan the surrounding airspace for conflicts.
In Canada, drone pilots must follow similar safety precautions and are subject to the Canadian Aviation Regulations. Drone pilots must fly safely and respect all other laws so as not to pose a danger to people or other aircraft. Drone operations within 3 nautical miles (5.6 kilometers) of an aerodrome under the authority of the MND require authorization from the MND aerodrome authorities.

Drone apps and software
Drone pilots must be aware of the rules and regulations regarding where they can fly their drones, especially near airports. Drones are considered aircraft and are therefore prohibited from entering certain zones without authorization. Before taking off near an airport, drone pilots must receive airspace authorization, which includes altitude limitations and other provisions. Controlled airspace restrictions can be found on apps provided by aviation authorities, such as the Federal Aviation Administration's (FAA) B4UFLY app. This app provides situational awareness to recreational flyers and other drone users, informing them of controlled airspace, special use airspace, critical infrastructure, airports, national parks, and military training routes.
To aid in safe and legal drone operations, several apps are available that offer a range of features, including airspace management, flight planning, and compliance. One such app is Aloft (formerly Kittyhawk), which integrates with the FAA's LAANC system, providing near-instant authorization to fly in controlled airspace. Aloft also offers real-time airspace advisories, customizable checklists, and risk assessments. Another app, Litchi, offers advanced autonomous flight features, including a waypoint mission engine that allows for the planning of complex flight paths with multiple waypoints. Litchi also includes modes like Focus, Panorama, Orbit, and Follow Me, enhancing the capture of aerial footage.
For weather checks, UAV Forecast is a useful app, while Google Maps aids in navigating unfamiliar areas. Drone pilots with DJI drones should utilize the DJI Go app, and for data processing, DroneDeploy provides automated processing and enhanced safety and quality checks. AirMap is another informative app, keeping drone pilots aware of airspace restrictions, while Tesla Field Recorder helps avoid magnetic interference. Lastly, Drone Buddy is an all-in-one app for various flight needs.
In addition to these apps, drone pilots must also be aware of other factors, such as aircraft noise and visual observation. Helicopter noise, in particular, should be considered as helicopters can operate at lower altitudes and be more unpredictable. Visual observers can assist in scanning the sky and communicating any potential conflicts. Before flying indoors, near, or over buildings, it is recommended to obtain permission from the building owner and/or occupants. Drone pilots should also consult resources like Notice to Airmen (NOTAMs) to be aware of events and obstacles that may impact their flight.

Drone weight and flight distance
Drone regulations vary depending on the region. In the United States, the Federal Aviation Administration (FAA) mandates that drones be flown within visual line of sight (VLOS). In Canada, drone pilots must follow the rules in the Canadian Aviation Regulations (CARs). These regulations require drone pilots to carry a valid drone pilot certificate and only fly marked and registered drones. If the drone weighs less than 250 grams, registration and certification are not required.
Drone weight directly impacts its range. Heavier drones require more power to stay airborne, limiting their range. Efficient motors and propellers help maximize flight range. For example, brushless motors use less energy than older models. Similarly, well-designed propellers reduce energy consumption, while damaged or unbalanced ones can limit the drone's range.
The controller's signal range also affects how far a drone can fly. Obstacles like buildings and trees can interfere with the signal, reducing the operational distance. Additionally, wind, temperature, and weather play significant roles in drone range. Headwinds reduce range by forcing the drone to use more energy, while tailwinds extend it. Extreme cold decreases battery efficiency, and high heat can cause overheating, both of which shorten flight distance.
Aggressive flying, such as rapid ascents, turns, and high speeds, quickly drains the battery, reducing the range. Smooth, steady flight at moderate speeds conserves energy and extends the drone's operational distance. Optimal flight speeds for endurance and range help determine the best speeds for different mission objectives, such as maximizing distance or conserving battery life.
