[Touchsky tutorial] Behind the scenes of the sailing story - drone sea ​​takeoff landing skills
Whether it is a film-quality professional drone such as Inspire, or a consumer-grade drone such as Phantom or Mavic, or even a toy drone with hundreds of pieces of Taobao, it is easy and convenient to take off and land with one button.
However, if you change the place, "one button" may not be good.
Today, the Touch teacher takes the Phantom 4 Pro as an example, and talks about how to take off the drone safely on the sea.
fly together
Be wide and steady - please brake
Taking off and taking aerial photographs on a moving ship has never been an easy task.
In addition to complex and variable conditions such as weather, temperature, and wind speed, factors such as signal strength, vessel stability, and take-off space need to be considered.
If you are riding a large ship, there is an open deck, and the top is unobstructed. There is no doubt that as long as the calm and the hull are not so swaying, you can use the deck as a flat ground and place the drone to take off with one button.
If it is a speedboat or a sailboat, such a bow is narrow, and the masts, sails, and rope-intensive ships cannot even find a piece of open space to take off.
In order to avoid collision with the ship and ensure a smooth take-off, it is best to choose to take off.
Because the boat is small and the sway is serious, it is necessary to take care of the plane taking off, and it is easy to get things off if you don't pay attention. Teacher Touch strongly recommends working with partners. When taking off, be sure to straighten the arm up and lift the plane over the top of the head. When the motor starts, feel the lift of the airplane and let go. Next, the rocker was pushed and the aircraft was successfully lifted off.

Second shot
Do not exceed the line of sight, do not exceed the picture, will not die
The basic shooting techniques of light, angle and composition are not much to say. You are all old drivers. Teacher Touch focuses on safety.
If you search for enough stars before take-off, you can see the return point H on the DJI GO 4 App map, but when you fly at sea, the usual dense map becomes a large blue piece. Due to the lack of relative position reference, after flying out It is easy to get lost. And the sea surface is very reflective, just staring at it with eyes, it is easy to lose the drone after flying far.
In addition to looking up at the sky to find the aircraft, but also look down on the flight data, such as the aircraft status prompt bar, power, flight status parameters, including distance, altitude, speed, etc., according to these data and prompts to adjust the attitude of the aircraft in time.
Of course, the safest thing is not to fly beyond the line of sight. This will not only capture the desired picture, but also ensure flight safety.

If it is an old driver, if you want to fly beyond the line of sight, you must not exceed the distance . After all, it is for shooting, not for the sake of death. Once the graph is broken, you can try to adjust the angle and posture of the antenna. There may be opportunities to connect.
If you change the 72 positions and you can't connect, and you can't trigger the uncontrolled return, it's not far from the control.
Three return flights, landing
Returning to the landing, relying on the hand, refreshing beyond the line of sight, avoiding the sword
Take off on the sea, remember that the drones and boats are in motion, and the return point needs to be constantly refreshed.
As can be seen from the figure, when the ship stops at [H], the drone takes off, then the drone has been flying around the sea, and the ship has started to move, but the recorded return point has not moved, if Clicking the return button at this time is equivalent to releasing a button.
In order to avoid repeating the tragedy of "seeking the sword and seeking the sword", I strongly recommend that you:
1. Don't look beyond the distance, don't over-the-horizon, don't over-the-horizon
2. It is strongly recommended to manually control the return flight. If you don't listen to the teacher's advice, you have to fly beyond the line of sight, then the best way to return to the neighborhood with a key to return, remember! Be sure to refresh the return point in time.
Set the remote control position in your hand to the return point, and after a while, the ship moves a little bit and refreshes it in time to ensure that the aircraft can be remotely controlled back when the aircraft returns. (According to the personal experience of the Touch teacher, it is recommended that the small partners manually refresh the return point when there is a network)
Take P4 P as an example. The specific operation is to select the return point setting in the settings, and then click OK.
3. Return to the vicinity of the ship and manually land the landing.
When the drone returns to the vicinity of the ship, it is necessary to leave more patience when landing. After all, the ship is shaking, and the rhythm of the ship's shaking can be slowly lowered. Teacher Touch recommends taking the plane by hand. Just like last time shooting "Drone and Sailing, Sea and Courage" , Touch teacher and small partner are picking up the plane by hand on a speedboat. The first day is fine, the weather is fine, there is no wind and no waves, standing at the stern You can pick up Phantom with one hand.

The next day, the wind and rain on the sea, the take-off and landing have repeatedly tried many times, not only to test the tacit understanding between the flying hand and the "holding hand", but also test the rapport between everyone and the waves, the sea breeze, several times want to land, both Because the huge waves came, the distance between the hull and the drone was pushed far away.
When landing, the enthusiastic captain brother insisted on helping to pick up the plane, and finally caught the drone. The older brother was excited. The motor didn't stop and wanted to put his hand down, scared the whole boatman to shout: Take it! Don't let it go!
When the small partners pick up the plane, they must hold it, wait for the motor to stop and then put down their hands.

Touch teacher questioning time:
1. I want to chase the boat or not:
A: Yes, if it is a cockroach, there are planes and yachts, just stop at any time and want to chase you happy.
B: If it is a general passenger cruise ship, the driving speed is about 20km/h; if it is a cross-sea transoceanic cruise ship, the speed is relatively fast and can run to 40~70km/h. And there are established routes. After the drone flies out, you can try to surround, point back and other operations, or you can take a lot of wonderful pictures. Don't fly too far, encounter the sea breeze, flying against the wind is not an easy task, oh, can't catch up with the ship and fall into the sea.
2. Can you fly close to the sea:
can. The last time the Touch teacher shot the sailboat, there were some shots that were shot close to the surface of the water.

However, according to experience, it is recommended to maintain a height of more than 5 meters. If the flight is too low, it is easy to be splashed by the sea water spray to the machine. When the weather is violent, the big waves come directly to the plane. Remember to clean the seawater in time after flying. The maintenance cost of the drone is not low, and everyone must pay attention to maintenance.
3. How big is the sea breeze, can the drone take off?
You can use the APP to check, and there are weather broadcasts on the ship, which will be broadcast regularly. At present, drones, like the inspire series of DJI, can withstand a maximum grace of 10m/s. It should be noted that the captain and crew on board generally say that the wind speed now has 5 knots and 6 knots. Everyone remembers 1 section = 1 nautical mile / hour = 1.852km / h, and then real-time conversion, you can know whether it is suitable for flying.
4. If the fly-out map is broken, the control signal is also broken, and it is out of control!
First of all, be sure to set the runaway behavior to return before taking off. Choose to drop the hovering partner and walk well.
If you are out of control at sea, the aircraft will trigger a runaway return. At this time, please wait patiently at the return point. If the power is enough, the plane can come back properly. Teacher Touch has measured it on land. On the sea...Touch teacher can only pray for heaven, and you don’t have to run out of control!
5. Does the Touch teacher have a masterpiece of the sea aerial photography?
Nani! The last "Sailboat Story" has not been seen yet? Have you seen it yet? I am not planning to reward this time? The boat of friendship, turned over and turned over in the first year!
3.2V 50Ah Li-ion Prismatic Cell
Is The Battery Cell Important to The Lithium Battery Performance?
