Anemometers for Drone Operators: Flying in Windy Conditions
When it comes to drone operations, understanding weather conditions—especially wind speed—is crucial to ensure a safe and successful flight. Anemometers, devices used to measure wind speed, are essential tools for drone operators, helping them make informed decisions before taking off. Whether you’re flying a drone swarm for a live event or operating a single drone for a TV or film production, knowing the exact wind conditions can make or break your project.
At Flying Glass, we’ve seen firsthand how unpredictable weather can impact drone operations, particularly wind. In this post, we’ll explore why anemometers are so critical for drone operators, how to use them, and when they’re required. We’ll also discuss where to buy reliable anemometers to ensure you’re always prepared for any flying conditions.
Why Wind Speed Matters: The Role of Anemometers for Drone Operators
Wind can be a drone’s worst enemy. While drones have become more stable and advanced in recent years, strong wind conditions can still pose significant risks. This is where anemometers come in—by providing real-time wind speed data, drone operators can assess whether it’s safe to fly.
For projects like drone swarms—where multiple drones must work together in perfect harmony—wind speed is a make-or-break factor. Drone swarms, often used for live events, concerts, or light shows, require optimal weather conditions. Even a slight increase in wind speed can destabilise the entire swarm, leading to a cancelled show. In these cases, anemometers are crucial tools that help operators decide whether to proceed or reschedule.
On the other hand, for TV and film productions, the stakes are different. The visual quality of aerial footage is a top priority, and flying in strong wind not only jeopardises safety but also affects the stability and smoothness of the shots. In fact, if you’re even thinking about using an anemometer on a TV set due to wind, chances are the conditions are already too harsh for filming. Productions of this nature usually require ideal weather conditions and are unlikely to go ahead in adverse circumstances.
When and Where to Use Anemometers for Drone Operations
Anemometers should be used in various scenarios to ensure safe drone operations. Here are some common situations where anemometers are a must:
1. Drone Swarms and Live Events
As mentioned earlier, drone swarms are highly sensitive to wind conditions. When managing a large number of drones, even a small change in wind speed can cause drones to drift off course, risking collisions and failed formations. Before starting a drone swarm show, it’s vital to check the wind speed with an anemometer on-site. Most swarm operations are grounded if wind speeds exceed a certain threshold, which could vary depending on the drones used.
2. TV and Film Productions
While TV and film productions are often rescheduled due to poor weather conditions, anemometers can be used as a secondary measure to assess whether it’s worth attempting to fly in borderline conditions. For film-grade drones carrying heavy payloads like cameras, the operational wind limit is typically lower than for smaller drones. Even a slight breeze can compromise shot stability, making anemometers critical for precise decision-making.
3. High-Altitude or Coastal Flights
When flying drones over coastal areas or at high altitudes, wind conditions can be unpredictable and change rapidly. For drone operators working in these environments, an anemometer is essential to gauge wind speed before every flight. Coastal areas, in particular, are prone to sudden gusts of wind that could endanger drone flights, making it important to have accurate, real-time data from an anemometer.
How to Use an Anemometer for Drone Operations
Using an anemometer is fairly straightforward, but there are a few tips to ensure you get the most accurate readings.
1. Turn on the Anemometer Before Setting Up Your Drone
Before setting up your drone for flight, power up the anemometer and let it calibrate. This ensures you have accurate wind speed data before committing to your flight plan. Make sure to hold the device steady and face it into the wind.
2. Take Readings from Multiple Locations
Wind conditions can vary depending on where you’re standing, particularly in areas with complex terrain. To get the most accurate data, take wind speed measurements from different spots around your takeoff area. This is particularly useful if you’re operating in a confined space or near buildings that might block wind flow.
3. Monitor Wind Speed Continuously
Wind conditions can change rapidly, especially during outdoor events or long film shoots. It’s a good idea to check the wind speed at regular intervals using the anemometer, even if conditions seem stable when you first set up.
When to Avoid Flying Based on Wind Speed
Every drone model comes with its own wind tolerance levels. Smaller drones may only handle wind speeds up to 10-15 knots, while larger drones used in film production can operate in winds up to 25 knots. For drone swarms, wind speed limits tend to be even stricter, as the collective operation of multiple drones makes them more susceptible to wind interference.
As a general rule of thumb, if the wind speed exceeds the manufacturer’s recommended limit, it’s best to cancel the flight or reschedule. Relying on your anemometer will help you avoid unnecessary risks, protecting your equipment and ensuring the safety of those around you.
Where to Buy Reliable Anemometers for Drone Operators
There are several places where you can purchase anemometers specifically designed for drone operations. When choosing an anemometer, make sure to look for features like accuracy, portability, and durability, as you’ll likely be using it in outdoor conditions.
Here are a few reliable options:
- Kestrel Anemometers: Known for their rugged design and high accuracy, Kestrel anemometers are ideal for drone operators who need dependable wind speed data in various conditions.
