Fixed Wing vs Multirotor Drones: Which Is Better for Inspection?

As the importance of drone aerial platforms has become increasingly recognized, the scope of drone services has expanded rapidly. Drone monitoring, drone mapping, and drone inspection all demonstrate the powerful potential of drones. However, with diverse drone types available, which type is best suited for your business?

In this guide, we will compare fixed-wing and multirotor drones, including their flight characteristics, coverage area, endurance, inspection capabilities, operating environments, and typical applications.

What is a Fixed-Wing Drone?

Fixed-wing drones employ a rigid wing design similar to that of an airplane, generating lift as they fly forward.

Unlike multirotor drones, fixed-wing drones typically cannot hover. They need to move forward to maintain flight.

Because their wings generate aerodynamic lift, fixed-wing drones are generally able to fly longer distances more efficiently and cover larger areas with less energy consumption.

This means that fixed-wing drones are primarily used for surveying and inspection tasks covering several square miles or over long distances with extended flight times.

Business personnel typically use fixed-wing drones for large-area mapping, land surveying, agricultural monitoring, pipeline corridor surveying, environmental monitoring, long-distance infrastructure inspection, and mine and quarry surveying...

What is a multi-rotor drone?

Multi-rotor drones use multiple rotating propellers to generate lift and control flight. Common multi-rotor drones include quadcopters, hexacopter drones, and octacopter drones.

Unlike fixed-wing drones, multi-rotor drones can hover, take off vertically, and land vertically. Common consumer and commercial drones use quadcopter designs, while agricultural/firefighting drones use hexacopter or octacopter designs.

The aerial characteristics of multi-rotor drones make them particularly suitable for detailed inspections and operations requiring precise positioning.

Therefore, multi-rotor drones are frequently found in scenarios such as power line inspection, wind turbine inspection, solar panel inspection, building inspection, bridge inspection, construction monitoring, industrial facility inspection, close-range photography and imaging, etc.

Fixed-wing Drones vs. Multi-rotor Drones: Key Differences

To help you better identify drone types and intuitively evaluate drone solutions, please see the following key performance comparison.

Feature	Fixed Wing Drone	Multirotor Drone
Flight efficiency	High	Moderate
Flight Time	Short (20-45 minutes)	Longer (1-4 hours+)
Long-distance missions	Excellent	Good
Large-area coverage	Excellent	Good
Hovering	No	Yes
Vertical takeoff and landing	Usually no	Yes
Close-up inspection	Limited	Excellent
Precision positioning	Moderate	Excellent
Confined environments	Less suitable	Highly suitable
Typical mission	Mapping and surveying	Inspection and detailed imaging

Both aerial platforms have their strengths and weaknesses, and both can adapt to various industry requirements for aerial operations. Typical examples include the Autel EVO Max series of multi-rotor UAVs and the Autel Dragonfish series of VTOL fixed-wing UAVs.

Industrial multi-rotor UAVs typically employ highly automated flight control, making them easier to operate, while fixed-wing UAVs require extensive professional training and are more difficult to operate, as stated in the Autel Dragonfish series training courses.

Fixed-Wing Drones vs. Multirotor Drones: Flight Endurance

Fixed-wing drones offer superior endurance and flight efficiency. Compared to multirotor aircraft, they consume relatively less energy to maintain flight.

A single fixed-wing drone can operate continuously for more than 4 hours per flight, covering distances of tens or even hundreds of kilometers. This makes fixed-wing platforms particularly suitable for long-duration missions.

The maximum standard flight time for enterprise-grade quadcopter drones is no more than one hour, and can be reduced to 30-40 minutes due to external conditions.

Fixed-wing Drones vs. Multi-rotor Drones: Coverage Area

For surveying and mapping large geographical areas, fixed-wing drones are often preferred over multi-rotor drones.

The long endurance and long-distance flight capabilities of fixed-wing drones allow for comprehensive mapping of large areas, such as forests, mining areas, large construction sites, utility corridors, and environmental surveys, collecting valuable image data.

Multi-rotor drones often employ box-type drone solutions to cover large geographical areas, but their efficiency is significantly lower than that of a single multi-rotor drone flight.

Fixed-wing Drones vs. Multi-rotor Drones: Hovering Capability

The hovering capability of a drone determines whether it can hover in the air, allowing operators to inspect specific objects from different angles and distances with zoom capabilities.

For infrastructure inspections such as power lines, power towers/poles, wind turbines, and bridges, image quality and anomaly localization are more important than total flight distance.

Multi-rotor drones can approach targets, hover, adjust their position, and capture detailed images using zoom or high-resolution cameras.

Taking specific images of an object while in flight is often prone to blurring and loss of focus. Therefore, for situations requiring detailed, stationary, or close-up inspections, multi-rotor drones are superior to fixed-wing drones.

Fixed-wing Drones vs. Multi-rotor Drones: Wind and Weather Conditions

Both fixed-wing and multi-rotor drones are mostly electrically powered. Poor external conditions can reduce motor power consumption and affect inspection time.

Although fixed-wing and multi-rotor drones have different aircraft designs and payloads, under the same weather conditions, the flight control system of a multi-rotor drone is better at maintaining position and compensating for the effects of wind.

Fixed-wing Drones vs. Multi-rotor Drones: Takeoff and Landing

There is a significant size difference between fixed-wing and multi-rotor drones. Multi-rotor drones can take off and land vertically, while traditional fixed-wing drones typically require a takeoff and landing area and are limited by space.

Multi-rotor drones, with their compact structure and support for vertical takeoff and landing (VTOL), are easier to deploy in confined spaces such as roadsides, rooftops, and small open areas. If your drone requires indoor operations, you'll need to further consider its indoor operational capabilities and resistance to interference.

With the development of drone technology, some fixed-wing drones now also possess VTOL capabilities. Autel drones call this technology tilt-rotor technology, which automatically switches between multi-rotor and fixed-wing modes based on the drone's status.

Fixed-wing Drones vs. Multi-rotor Drones: Operational Complexity

Operating either fixed-wing or multi-rotor drones for aerial inspections requires pre-checking the drone's flight status, planning its flight path, conducting visual aerial inspections, and returning to retrieve data reports.

However, operating fixed-wing drones may require more planning, especially for traditional aircraft that require suitable takeoff and recovery areas.

Drone manufacturers tend to produce VTOL fixed-wing drones, which can reduce this limitation by combining VTOL with fixed-wing cruise flight.

Comparison of Fixed-Wing and Multi-Rotator Drones in Drone Inspection

Drone inspection is a reliable and sustainable business, and the choice of which type of drone to use largely depends on the specific assets.

Both types of drone platforms can play a role in power line inspection, pipeline inspection, solar power plant inspection, wind turbine inspection, and construction site inspection.

Fixed-wing drones offer efficient coverage, while multi-rotor drones can collect detailed data at close range.

What about VTOL fixed-wing drones?

VTOL fixed-wing drones combine the characteristics of both aerial platforms.

VTOL stands for Vertical Take-Off and Landing. These drones can take off and land vertically like multi-rotor drones and then transition to efficient fixed-wing flight.

For organizations requiring both large-area coverage and flexible deployment, VTOL fixed-wing drones can be a very attractive option.

However, the additional mechanical structure and flight control complexity also make VTOL systems more complex than traditional multi-rotor drones.
