Drone aircraft technology is a complex system that relies on various components to function. These components include motors, propellers, and flight controllers.
A drone's motor is its heart, responsible for converting electrical energy into mechanical energy. Drones can have between one and six motors, depending on the design.
Flight controllers, also known as flight control systems, are the brain of a drone. They process data from sensors and control the drone's movements.
Propellers are the drone's wings, responsible for generating lift and thrust. Drones can have different types of propellers, such as fixed pitch or variable pitch.
The size and weight of a drone's components can affect its overall performance and efficiency.

Design
Design plays a crucial role in the development of UAVs, allowing for flexibility and innovation. The absence of a cockpit and the need for human comfort means UAVs can be designed with different configurations.
For example, small civilian UAVs can be built out of lighter materials and shapes, and use less robust electronic control systems. This is because they don't require life-critical systems like crewed aircraft do.
The quadcopter design has become popular for small UAVs, but it's rarely used for crewed aircraft. This is due to the miniaturization of UAVs, which allows for the use of less-powerful propulsion technologies like small electric motors and batteries.

Control systems for UAVs are often different from crewed craft. For remote human control, a camera and video link replace the cockpit windows, and radio-transmitted digital commands replace physical cockpit controls.
Autopilot software is used on both crewed and uncrewed aircraft, with varying feature sets. This allows for greater flexibility and customization in UAV design.
Here are some key differences in UAV design compared to crewed aircraft:
These differences allow UAVs to be designed with specific payloads and ground equipment in mind, rather than human comfort and safety.
Fixed-Wing
Fixed-wing drones are a popular choice for various applications, including aerial mapping, drone surveying, agriculture, inspection, construction, and security. They offer a unique combination of advantages, such as energy efficiency and the ability to cover longer distances.
One of the key benefits of fixed-wing drones is their ability to fly at high altitudes and carry more weight than other drone types. This makes them ideal for applications that require a lot of payload capacity, such as aerial mapping and drone surveying.
Here's an interesting read: List of Unmanned Aerial Vehicle Applications
Fixed-wing drones can be expensive, and training is usually required to fly them. This is because they require a certain level of skill to control through the flight and back to a soft landing, especially when compared to multi-rotor drones.
Here are some of the key applications of fixed-wing drones:
- Aerial Mapping
- Drone Surveying – Forestry/Environmental Drone Surveys, Pipeline UAV Surveys, UAV Coastal Surveys
- Agriculture
- Inspection
- Construction
- Security
Fixed-wing drones can also be used for tasks such as aerial LIDAR laser scans and carrying heavy payloads. This makes them a versatile option for a wide range of applications.
Weight
When designing a drone, weight is a crucial factor to consider. Drones can be classified into five categories based on their weight.
A nano drone weighs less than 250 grams. This tiny size allows for incredible agility and maneuverability, making them perfect for indoor flights or capturing unique aerial footage.
The weight of a micro air vehicle (MAV) is between 250 grams and 2 kilograms. This size is ideal for small outdoor flights and can be a great starting point for hobbyists.
Miniature UAVs or small UAVs (SUAVs) typically weigh between 2 kilograms and 25 kilograms. This size is often used for surveillance and inspection missions, where a compact design is essential.
Medium UAVs weigh between 25 kilograms and 150 kilograms. This size is commonly used for commercial applications, such as aerial photography and mapping.
Large UAVs are the heaviest, weighing 150 kilograms or more. These drones are often used for heavy-lift applications, such as carrying large payloads or operating in harsh weather conditions.
Here's a quick reference table to help you determine the weight category of your drone:
Components and Systems
Drones have a range of components that work together to enable flight and advanced features. The flight controller, a crucial component, is a single module that incorporates a primary microprocessor, a secondary or failsafe processor, and sensors such as accelerometers, gyroscopes, magnetometers, and barometers.
The flight controller is often referred to as the autopilot, and it's designed to facilitate the integration of drones into the airspace. In 2024, EASA agreed on the first certification basis for a UAV flight controller in compliance with the ETSO-C198 for Embention's autopilot.
For another approach, see: Drone Remote Controller
Drone components also include electronic speed controllers, which manage a motor's speed and direction, as well as GPS modules, batteries, antennas, receivers, and cameras. Some drones also feature gimbals, which stabilize the camera from vibration, wind, or other movement.
Here are some common drone features and components:
- Electronic speed controllers
- Flight controller
- GPS module
- Battery
- Antenna
- Receiver
- Cameras
- Gimbals
- Sensors (accelerometers, ultrasonic sensors, collision avoidance sensors, etc.)
Propulsion
Propulsion systems for drones are diverse and dependent on the mission requirements. For long-range flights, traditional internal combustion and jet engines are still used.
The distance record for a UAV crossing the North Atlantic Ocean is held by a gasoline-powered model airplane or UAV, which flew 1,882 miles on less than a gallon of fuel in 2003.
Electric power has become the norm for shorter-range missions, offering quieter and more efficient operation. This is due to advancements in lithium-polymer batteries (Li-Po), which are used in most small drones.
The Wankel rotary engine is another option, providing high power output for lower weight and quieter running. It's also claimed to offer improved reliability and greater range.

Here's a breakdown of the main propulsion types:
Hybrid and hydrogen fuel cell propulsion systems are being developed to offer longer flight times and zero emissions. However, these technologies are still in the early stages of development.
Computer Control Systems
Computer control systems play a crucial role in the operation of drones. Modern system hardware for UAV control is often called the flight controller (FC), flight controller board (FCB) or autopilot.
The flight controller is a single module that incorporates a primary microprocessor, a secondary or failsafe processor, and sensors such as accelerometers, gyroscopes, magnetometers, and barometers. This integration of hardware and software enables drones to fly autonomously or with remote-pilot input.
In 2024, EASA agreed on the first certification basis for a UAV flight controller in compliance with the ETSO-C198 for Embention's autopilot. This certification aims to facilitate the integration of UAVs within the airspace and the operation of drones in critical areas.

Drones rely on single-board computers for their computational needs, which are typically shielded with NavIO, PXFMini, or designed from scratch. Examples of such single-board computers include Raspberry Pis, Beagleboards, and NuttX, preemptive-RT Linux, Xenomai, Orocos-Robot Operating System, or DDS-ROS 2.0.
Here's a breakdown of the layers of the flight stack:
Actuators
Actuators play a crucial role in the overall functionality of a UAV.
UAV actuators include digital electronic speed controllers, which control the RPM of the motors, and are linked to motors/engines and propellers.
These digital speed controllers are a vital component, as they allow for precise control over the speed of the motors.
Servomotors are also used in UAVs, particularly in planes and helicopters, to provide precise control over movement.
Weapons and payload actuators require precise control as well, to ensure safe and accurate deployment.
LEDs and speakers are also types of actuators used in UAVs, often for communication and visibility purposes.

Multi-Rotor
Multi-Rotor drones are the easiest and cheapest option for getting an 'eye in the sky'. They offer greater control over position and framing, making them perfect for aerial photography and surveillance.
Multi-rotor drones have more than one motor, commonly tricopters (3 rotors), quadcopters (4 rotors), hexacopters (6 rotors), and octocopters (8 rotors). Quadcopters are the most popular multi-rotor drones.
One of the advantages of multi-rotor drones is that they provide better control of the aircraft during flight. This is due to their increased manoeuvrability, which allows them to move up and down on the same vertical line, back to front, side to side, and rotate in their own axis.
Multi-rotor drones can also fly much more closely to structures and buildings, and have the ability to take multiple payloads per flight, increasing operational efficiency and reducing the time taken for inspections.
However, multi-rotor drones have some limitations. They have limited endurance and speed, making them unsuitable for large scale aerial mapping, long-endurance monitoring, and long-distance inspection such as pipelines, roads, and power lines.
The current battery technology limits multi-rotor drones to around 20-30 minutes of flight time when carrying a lightweight camera payload. However, heavy-lift multi-rotors can carry more weight, but in exchange for much shorter flight times.
Multi-rotor drones are restricted to electric motors, as they require fast and high-precision throttle changes to keep them stabilised. This makes them unsuitable for gas engines.
Here are some technical uses of multi-rotor drones:
- Visual inspections
- Thermal reports
- Photography & Videography
- 3D scans
Single-Rotor
Single-Rotor Drones have a lot going for them. They're strong and durable, with a structure and design that's similar to actual helicopters. This makes them great for carrying heavy payloads, like aerial LIDAR laser scanners, and they can also provide long endurance.
Their efficiency is one of their biggest advantages, especially when gas-powered. This means they can fly for a long time without needing to recharge. In fact, a single-rotor drone can have blades that are more like spinning wings than propellers, giving them great efficiency.
However, this also means they require a lot of maintenance and care. Their mechanical complexity can be a real challenge to deal with. And if you're not careful, the long, heavy spinning blades can be downright dangerous.
Here are some key benefits and drawbacks of Single-Rotor Drones:
Fixed-Wing Hybrid Vtol
Fixed-Wing Hybrid VTOL is a type of drone that combines the benefits of fixed-wing and rotor-based designs. This allows it to hover and take off and land vertically.
A unique perspective: Wing Delivery Drones
The autopilot system in these drones is capable of doing all the hard work of keeping the drone stable, leaving the human pilot to guide it around the sky.
One of the key advantages of fixed-wing hybrid VTOLs is that they can perform both hovering and forward flight with ease.
Only a handful of these drones are currently on the market, and the technology used in them is still in its early stages.
These drones offer the best of both worlds, allowing for vertical takeoff and landing, as well as efficient forward flight.
Here are some key characteristics of fixed-wing hybrid VTOLs:
- Can hover and take off and land vertically
- Perfect for either hovering or forward flight
Training in Technology
Training in drone technology is expanding rapidly, with institutions like Embry-Riddle Aeronautical University offering degree programs in Uncrewed Aircraft Systems.
Drone education is not limited to formal institutions, as there are also self-study resources available for individuals who want to become certified commercial drone pilots.
Basic drone training topics typically include introduction to drones, regulations and compliance, basic flight training, and safety protocols.
More advanced topics might cover advanced piloting skills, mission planning and execution, and payload and sensor integration.
Some drone training providers offer specialized courses in commercial applications, industrial applications, and emergency and safety applications.

This growth will be fueled by the evolution of complementary technologies like fifth-generation wireless (5G), AR, and computer vision, which will improve drone communication and intelligence.
Range and Endurance
Range and endurance are crucial performance metrics for UAVs. UAVs can be classified into five categories based on their range and endurance.
UAVs with very close range and endurance are limited to less than 5 kilometers and 0.5-0.75 hours of flight time.
Close range UAVs have a range of over 5 kilometers but less than 50 kilometers and can stay aloft for 1-6 hours. Short range UAVs have a range of over 50 kilometers but less than 150 kilometers and can fly for 8-12 hours.
Related reading: Long Endurance Uav
Medium range UAVs have a range of over 150 kilometers but less than 650 kilometers and can stay airborne for 12-36 or 48 hours. Long range UAVs have a range of over 650 kilometers and can fly for more than 36 or 48 hours.
Proper cooling is essential for long-term drone endurance, and overheating is the most common cause of drone failure.
Some UAVs have achieved remarkable endurance records, including the Boeing Condor, which stayed aloft for 58 hours and 11 minutes in 1989, and the QinetiQ Zephyr Solar Electric, which flew for 82 hours and 37 minutes in 2008.
Here are some notable UAV endurance records:
Altitude
Altitude plays a crucial role in determining the performance and capabilities of an aircraft. The altitude at which an aircraft operates can significantly impact its range, speed, and overall effectiveness.
Hand-held aircraft have a relatively low altitude of 2,000 ft (600 m) and a range of about 2 km. Close-range aircraft can operate at 5,000 ft (1,500 m) and have a range of up to 10 km.
Worth a look: High Altitude Long Endurance Uav
The NATO type aircraft can reach an altitude of 10,000 ft (3,000 m) and have a range of up to 50 km. Tactical aircraft can operate at 18,000 ft (5,500 m) and have a range of about 160 km.
MALE (medium altitude, long endurance) aircraft can reach an altitude of up to 30,000 ft (9,000 m) and have a range of over 200 km. HALE (high altitude, long endurance) aircraft can operate at an altitude of over 30,000 ft (9,100 m) with an indefinite range.
Hypersonic aircraft can reach an altitude of 50,000 ft (15,200 m) or suborbital altitude and have a range of over 200 km. Orbital aircraft can operate at low Earth orbit (Mach 25+).
Reliability
Reliability is a top priority for UAV systems, with improvements targeting all aspects of the technology.
Individual reliability focuses on the robustness of flight controllers, ensuring safety without excessive redundancy to minimize cost and weight.
Dynamic assessment of the flight envelope allows damage-resilient UAVs, using non-linear analysis with ad hoc designed loops or neural networks.
UAV software liability is shifting towards the design and certifications of crewed avionics software.
Swarm resilience involves maintaining operational capabilities and reconfiguring tasks given unit failures.

Nuisance
Drones can pose a significant threat to airspace security, including unintentional collisions or interference with other aircraft.
In 2017, the first incident of a drone-airplane collision occurred in Quebec City, Canada.
Unauthorized UAV flights into or near major airports have prompted extended shutdowns of commercial flights, including a significant disruption at Gatwick Airport in December 2018.
Flying close to a wildfire in the United States is punishable by a maximum $25,000 fine.
The FAA later required registration of most UAVs in response to incidents like those that hindered firefighting air support in California in 2014 and 2015.
Regulation
Regulation plays a crucial role in ensuring the safe operation of unmanned aircraft systems (UAS). Regulatory bodies around the world are developing UAS traffic management solutions to better integrate UAVs into airspace.
The use of unmanned aerial vehicles is becoming increasingly regulated by civil aviation authorities. In 2005, the International Civil Aviation Organization (ICAO) began exploring the use of drone technology, resulting in a 2011 report. France was among the first countries to set a national framework based on this report.
Regulatory regimes can differ significantly according to drone size and use. The Federal Aviation Administration (FAA) requires all commercially used UAVs weighing 250 g or more to participate in Remote ID, making drone locations, controller locations, and other information public from takeoff to shutdown.
The FAA has also established specific rules for safe operation, including the requirement that a small unmanned aircraft system be in a condition for safe operation prior to each flight. The remote pilot in command must check the system to determine whether it is in a condition for safe operation.
Additionally, the FAA prohibits the carriage of hazardous material on small unmanned aircraft. The term "hazardous material" is defined in 49 CFR 171.8.
In some cases, the FAA may issue a certificate of waiver authorizing a deviation from any regulation specified in § 107.205 if the Administrator finds that a proposed small UAS operation can safely be conducted under the terms of that certificate of waiver.
In-Flight Emergency
In an in-flight emergency, the remote pilot in command may deviate from any rule to the extent necessary to meet that emergency.
If an emergency occurs, the remote pilot in command must be prepared to take immediate action, which may involve deviating from standard procedures.
The remote pilot in command must, upon request, send a written report of any deviation from a rule to the Administrator.
This report helps ensure that the actions taken during the emergency are reviewed and can inform future regulations and safety protocols.

Remote Pilot and Operations
To operate a drone, you need a remote pilot certificate with a small UAS rating, unless you're under the direct supervision of a remote pilot in command who can take control of the drone at any time.
The remote pilot in command must be designated before or during flight and is responsible for ensuring the drone poses no hazard to others and complies with all applicable regulations.
To operate a drone from a moving vehicle or aircraft, you must fly over a sparsely populated area and not transport another person's property for compensation or hire.
Remote Pilot
To become a remote pilot, you'll need to obtain a remote pilot certificate with a small UAS rating. This requires passing an initial aeronautical knowledge test or holding a pilot certificate issued under part 61 of this chapter and meeting the flight review requirements specified in § 61.56.
The application process for a remote pilot certificate involves submitting a form and manner acceptable to the Administrator, along with evidence of passing the knowledge test or meeting the flight review requirements. If you're applying using a paper application, you'll need to provide an airman knowledge test report showing passage of the knowledge test.
A remote pilot certificate is typically issued for up to 120 calendar days, after which a permanent certificate will be issued to a person whom the Administrator finds qualified under this part. You can also receive a temporary remote pilot certificate with a small UAS rating, which expires on the expiration date shown on the certificate or upon receipt of the permanent certificate.
To be eligible to act as a remote pilot in command, you must have a remote pilot certificate with a small UAS rating issued pursuant to Subpart C of this part and satisfy the requirements of § 107.65. You must also be designated as the remote pilot in command before or during the flight of the small unmanned aircraft, and be directly responsible for and the final authority as to the operation of the small unmanned aircraft system.
From a Moving Vehicle
Flying a small unmanned aircraft system from a moving vehicle can be a bit tricky. You must fly over a sparsely populated area.
You'll need to comply with the provisions of §§ 91.17 and 91.19 of this chapter, which means following specific rules and regulations.
This includes ensuring you're not transporting another person's property for compensation or hire. It's not just about the type of aircraft, but also the type of operation.
You can't fly at night, so plan your operations accordingly.
At Night
Operating a small unmanned aircraft system at night requires extra caution and specific equipment. The remote pilot in command must have completed an initial knowledge test or training after April 6, 2021.
The small unmanned aircraft must have lighted anti-collision lighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision. The remote pilot in command may reduce the intensity of the lighting if necessary, but not extinguish it.
In periods of civil twilight, the small unmanned aircraft must also have lighted anti-collision lighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision. Civil twilight refers to the time between 30 minutes before official sunrise and official sunrise, or between official sunset and 30 minutes after official sunset, except in Alaska.
In Alaska, the period of civil twilight is defined in the Air Almanac. After May 17, 2021, no person may operate a small unmanned aircraft system at night in accordance with a certificate of waiver issued prior to April 21, 2021.

Visual Observer
As a remote pilot, you may be wondering if you can have someone else help you keep an eye on the aircraft while you're flying it. The answer is yes, but only if you have a visual observer who meets certain requirements.
The visual observer must be able to see the unmanned aircraft in the manner specified in § 107.31, which means they must be able to see it at all times and know its location, attitude, altitude, and direction of flight.
The remote pilot in command, the person manipulating the flight controls, and the visual observer must maintain effective communication with each other at all times, as specified in § 107.33.
The visual observer's job is to scan the airspace for potential collision hazards and maintain awareness of the aircraft's position through direct visual observation.
The remote pilot in command must ensure that the visual observer can see the aircraft, and all parties must coordinate to scan the airspace and maintain awareness of the aircraft's position.
Operating Limitations and Prohibitions
Operating a small unmanned aircraft system comes with its set of rules. The groundspeed of the aircraft may not exceed 87 knots (100 miles per hour).
To fly safely, the altitude of the aircraft cannot be higher than 400 feet above ground level, unless you're flying within a 400-foot radius of a structure. In that case, you can fly higher, but not above the structure's immediate uppermost limit.
The minimum flight visibility must be no less than 3 statute miles from the control station. This means you need to be able to see prominent objects at a certain distance.
Operating Limitations and Prohibitions
Operating a small unmanned aircraft system (sUAS) comes with a set of rules to ensure safe and responsible operation.
The groundspeed of the sUAS may not exceed 87 knots (100 miles per hour).
You need to maintain a minimum flight visibility of no less than 3 statute miles from the control station.
Flight visibility means the average slant distance from the control station at which prominent unlighted objects can be seen and identified by day and prominent lighted objects can be seen and identified by night.
The minimum distance of the sUAS from clouds must be no less than 500 feet below the cloud.
You cannot operate a sUAS under this part with Automatic Dependent Surveillance-Broadcast (ADS-B) Out equipment in transmit mode unless otherwise authorized by the Administrator.
You also cannot operate a sUAS under this part with a transponder on unless otherwise authorized by the Administrator.
The altitude of the sUAS cannot be higher than 400 feet above ground level, unless you're flying within a 400-foot radius of a structure and not higher than 400 feet above the structure's immediate uppermost limit.
Temporary Certificate
A temporary remote pilot certificate with a small UAS rating is issued for up to 120 calendar days. This means you'll have a limited time to get your permanent certificate once you've been deemed qualified.
The temporary certificate expires either on the date shown on the certificate or when you receive your permanent certificate. This temporary status gives you a short window to get your affairs in order before being fully certified.
You can expect to receive a permanent certificate after your temporary one has expired, assuming the FAA finds you qualified.
Security Prohibitions and Exclusions
If you're operating unmanned aircraft systems, you need to be aware of the security prohibitions and exclusions in place.
The Federal Acquisition Regulation (FAR) prohibits the procurement and operation of unmanned aircraft systems from covered foreign entities.
Acquisitions, including contracts at or below the micro-purchase threshold, are subject to this prohibition.
The FAR also applies to contracts for commercial products or services.
Here are the specific sections of the FAR that address this prohibition:
- 48 CFR Part 40, Section 40.202
- 48 CFR Part 4, 13, 39, 40, and 52
These sections prescribe policies and procedures regarding the procurement and operation of unmanned aircraft systems, including drones and associated elements.
The FAR also requires agencies to review and comment on proposed rules, such as the one mentioned in the document details section, which has a document number of 2024-26061 and a RIN of 9000-AO70.
Security and Compliance
Security and compliance are crucial aspects of drone aircraft use. The Federal Trade Commission has demonstrated the ability to hack into consumer quadcopters, highlighting the need for manufacturers to implement basic security measures such as encrypting Wi-Fi signals and adding password protection.
To ensure compliance, remote pilots must have their remote pilot certificate with a small UAS rating and identification readily accessible. They must also present this certificate upon request from authorized representatives, including the Administrator, law enforcement officers, or the Transportation Security Administration.
The FAA requires remote pilots to make available any documents, records, or reports required to be kept under the regulations of this chapter. This includes declarations of compliance, which must be made available to the Administrator upon request. The Administrator also has the right to inspect facilities, technical data, and manufactured small UAS to determine compliance with regulations.
The export of UAVs or technology capable of carrying a 500 kg payload at least 300 km is restricted in many countries by the Missile Technology Control Regime.

Solicitation Provisions and Contract Clauses
The Solicitation Provisions and Contract Clauses are crucial for ensuring security and compliance in government contracts.
A new clause, 52.240-1, Prohibition on Unmanned Aircraft Systems Manufactured or Assembled by American Security Drone Act—Covered Foreign Entities, has been added to section 52.212-5.
This clause prohibits the delivery of unmanned aircraft systems manufactured or assembled by covered foreign entities.
The clause also applies to subcontracts for commercial products or commercial services, requiring contractors to insert the substance of this clause in all subcontracts.
The Federal Acquisition Security Council (FASC) maintains a list of covered foreign entities, which is published in the System for Award Management (SAM).
Contractors are prohibited from delivering or operating FASC-prohibited unmanned aircraft systems, which include drones and associated elements.
The prohibitions do not apply where the agency has determined an exemption, exception, or waiver applies, and the contract indicates such a determination has been made.
Contractors must insert the substance of this clause in all subcontracts and other contractual instruments, including subcontracts for the acquisition of commercial products or commercial services.
