As we are presently in spring and with summer season rapidly approaching, individuals are taking pleasure in a growing number of water-based activities. A few of these activities will be recorded by drone.
A concern that usually develops around this time of year, after the lakes and ponds have unfrozen and folks return to the waterways is:
What actions are required to fly a drone securely and with confidence around and above water, and guarantee it returns house?
In this short article and the consisted of YouTube video, we will discuss different pointers and actions required to fly any drone over water securely, along with some weather-related factors to consider to help in this. We’ll be utilizing DJI drones for the detailed parts of this short article.
1. Strategy, Strategy, Strategy
Strategy or understand your environment. This is a basic declaration, however really filled.
Among the fantastic features of numerous modern-day drones is their size and mobility. Since of this, we can quickly toss a collapsible drone in a bag or in a car and fly when near an intriguing area.
If we remain in a place we understand like the back of our hand, flying that location’s waterways need to be no huge concern.
Understanding the location, nevertheless, implies:
- understanding the environment’s residents such as birds and other wildlife that can position a hazard to your drone
- understanding if there are real no-fly zones that converge the water
- understanding if there are seaplanes or helicopters in the area
- understanding if there are drone no-fly zones published by the city government
If you are preparing an real journey to a particular, formerly unidentified location, like someplace on getaway, then it is advised to prepare the flight.
Preparation your flight can be carried out in the following methods:
Consult Google Maps or Apple Maps
This is a simple primary step, as it generally just needs putting in an address, or an address in the area of your travel location, putting the map in hybrid view (to see the streets, landscape, and topography), and after that scrolling around the map at a zoom that works for your view.
Research Study Utilizing Drone-Specific Apps
After getting an ordinary of the land with Google or Apple Maps, utilizing a drone-specific app can assist dive much deeper and see what kinds of airspace and cautions remain in the area.
Apps that can help in this, that we advise are:

2. Pre-Flight Checks
Something advised by the majority of drone operators, no matter where flying, is preflight checks.
Why is this so crucial? Since unlike flying over land, the opportunities of recovering an immersed drone may be really little, whereas a crashed drone, on land, can more quickly be recuperated, with very little damage.
A few of the significant locations to inspect, prior to flying are:
- Batteries Drone and Remote Controller
- Props
- GPS Satellite lock
- Go back to house. We will discuss this more
While these locations are very important to inspect prior to flight, there are naturally much more locations that need to be integrated to the pre-flight procedure prior to any flight, all of which can conserve your drone from “drowning” or crashing into an individual or residential or commercial property.

3. Shut Off Vision Positioning Systems (VPS) in DJI Go 4
Now this is an intriguing idea, one that even DJI suggests.
Note: This action is just for those utilizing the older DJI Go 4 app to fly their drones. The more recent DJI Fly app and the drones related to it (DJI Air 2 and Two, Mini 2, 3, and 3 Pro, along with the Mavic 3 series) can not switch off the VPS system.
In other words, VPS is an innovation utilized by DJI drones to map the surrounding surface area listed below the drone, helping in its positioning. This partly assists keep it consistent when there is no stick input.
Since water is a reflective surface area, flying over it with VPS on can trigger problems, among which is the drone trying to land in the water when too near to the surface area.
To disable the Vision Positioning System (VPS) in DJI drones running DJI Go 4:
ACTION 1: Enter Into the Go 4 menu system by tapping the 3 dots in the upper right-hand corner of the screen.
ACTION 2: Find and go into the sensing unit( s) tab on the left-hand side of the screen.
ACTION 3: Make Sure Challenge Avoidance is made it possible for.
ACTION 4: Enter Into Advanced Settings.
ACTION 5: Shut Off “Make It Possible For Vision Positioning.
4. By Hand Update House Point
This idea is more for those that will be shooting over the water from a boat, kayak, or other kind of boat.
When on a moving boat, it is essential to upgrade the house point routinely, as the drone operator may be in numerous areas throughout the time of the flight. When it comes to an RTH (go back to house) occurrence, it is advantageous for the drone to go back to the present area
Those that strategy to movie waterways and will be walking the length of the coast may likewise take advantage of upgrading the house point routinely, as one might quickly be rather a range from the preliminary launch website.
For shooting waterways, you can either:
- By hand set the house point
- Set the house indicate follow the remote controller This is finest for when on a boat.
To upgrade the house point in the DJI Fly app:
ACTION 1: After entering into the basic settings, under the Security tab enter into Update House Point.
You will then be given the change house point map.
ACTION 2: Drag the map around up until the H (house point) has actually been relocated to where you ‘d presently like it.
If you want to set the remote controller as your house point, merely push the RC icon and the house point will be set to the controller.
5. Know the Weather Condition and Conditions
Another really crucial thing to understand or research study when flying over water is what the weather condition is going to resemble. In specific, understanding the wind and wind gust speed.
Sure you can take a look around and see quite plainly if it is going to rain, nevertheless, understanding what the wind is doing a couple of hundred feet above the water can indicate the distinction in between an effective flight or a downed or lost drone.
When it concerns wind, although it may be continuous at 3 or 4 miles per hour a couple of lots feet from the ground, as soon as at 100 or 200 feet in height, that breeze can all of a sudden become raving gusts, making it tough to manage the drone and even return the drone to your present position.
Likewise, wind speed can rapidly diminish a drone battery, triggering other kinds of problems (discussed later on).
Another thing to think about is something called convective currents.
Convective currents are impacted by items that hold or produce either heat or cold. Depending upon the source impacting them will identify how your drone will fly through the present.
For example, if flying on a summer season day and a drone removes from a hot car park, the air currents press the drone upwards (hot air increases).
As soon as that drone starts to cross a cooler location throughout flight, state a body of water, the currents will lower on the drone (cool air falls).
Knowing these currents can help in keeping a drone out of the water if flying too low.
In these circumstances, the drone operator can be gotten ready for the unfavorable action of the present when flying over cool water in the summer season, and change appropriately.
6. Bear In Mind Obstacles
When flying around and over waterways, there are barriers to be familiar with that a person may not usually experience when flying over land.
Waves and Seaspray
Knowing waves and seaspray truly impacts those bold drone operators that intend to solve in on the action with their shots.
An unwary wave can and has actually gotten the drones of those that are paying more attention to the shot instead of their environments.
Seaspray is likewise an opponent of drones.
Although it may not trigger a drone to right away fall from the sky, there might be destructive results to the drone in time as the internals of the drone starts to wear away from direct exposure to seawater.
Boats
When shooting boats, it is suggested to keep a sensible range. As the stating goes “items in mirror are more detailed than they appear”.
Also, a boat, while shooting, might appear a lot even more away than it truly is either to the naked eye, from a range, or on a small clever gadget screen.
I have actually personally seen drones crash into boats while shooting. Once again, this is mainly since of not taking notice of the instant shooting location or misjudging the boat’s course.
Birds
Living and shooting in a state where predatory birds are rather typical, it is a should to keep an eye out for these and strategy appropriately when shooting in their area.
This is a sensitive topic for me, as I have actually been the regrettable recipient of an osprey strike that drowned among our drones. Fortunately I had the ability to swim and obtain it.
An excellent idea when flying near water is to bring the drone up a couple of lots feet above where it released and wait a couple of seconds to see if any birds reveal interest in it. If none do, then you are excellent to fly.
If any birds do attempt to engage the drone, fly directly to prevent them, as birds can not fly directly. After doing this a couple of times, the birds probably will lose interest, if not near their nest.
If flying in the area of a nesting bird, it is best to fly far from the instant location.
Alligators
If you reside in Alabama, Florida, Georgia, Louisiana, or Texas (simply among others), bewaring of alligators is advised.
Alligators can release themselves from the water to a height of 5 feet.
This is something they frequently do to get birds and rodents off low-lying limbs and branches over the water. They can do the exact same to low-flying drones.
There has actually been at least one just recently recorded news occurrence of an alligator getting a drone out of the sky and after that the drone ignited as the alligator chewed on it, no doubt triggering some damage to the alligator.
There’s a mindset Floridians have which is, if there’s water, presume there’s a gator in it This kind of believing might one day conserve a drone if flying in the discussed states.
7. Prevent Running Batteries Down Totally
This may seem like a no-brainer, nevertheless, when in the middle of flying, one can rapidly lose a sense of time and be entirely surprised when the drone starts to start RTH (go back to house) due to an absence of battery portion.
The factor it is best to prevent running batteries down entirely is based upon something discussed early, that being wind.
When flying along seasides, over open water, and low-lying lakes, the wind can kick up actually out of no place.
If the drone is out a couple of hundred backyards, on just a few percent battery life, and the drone is flying versus the wind, there is an extremely strong opportunity the drone will not make it back house.
Once Again, this is something that is well recorded online, where numerous individuals have actually lost their drones to wind due to not having enough battery portion to return to the house point.
We are constantly recommending landing around the 25% to 30% mark, for battery health. When it concerns flying around oceans and lakes, this procedure can show advantageous.
8. Usage Intelligent Flight Modes
This last idea refers choice.
Lots of more recent drones have some sort of smart flight mode integrated in, whether it be some sort of course lock, Sight mode, or follow-me mode.
When flying over water, utilizing something like a course lock or follow-me mode (for boats or jet skis) will allow the operator to either “set a course and forget it” or draw a box around a boat, let the drone do its thing, while the pilot concentrates on the shot or video and minding things like battery portion, and so on

General Tips
Suggested Flying Height
When it concerns flying over water, something to bear in mind is the very best minimum height to securely fly the drone without losing it to water.
DJI highly recommends flying no lower than 3 feet (1 meter) above the water’s surface area.
This is essential, as we have actually discussed, waves can kick up triggering the drone to be lost, convective currents can trigger the drone to all of a sudden dip, or the drone might start landing treatments believing the water’s surface area is the ground.
Beach Launches
When flying on the beach, it is encouraged to bring along a landing pad, as releasing from one decreases the quantity of sand that can be blown into the motors and even the drone’s internals.
If you do not have a landing pad, in a pinch, I personally have actually utilized and advise utilizing a floormat from inside the vehicle.
Just position the rubber end of the mat on the sand (if you have mats that likewise have a carpeted side) and go. This works effectively, albeit a little troublesome, as mats do not fold for simple storage in an equipment bag.
