Guide to Flying in Winter

In the winter when dripping water turns into ice, the temperature drops off guard! Affected by low temperature weather and environment, if you rush into battle without adequate preparation, you will inevitably encounter unexpected embarrassment or even accidents. < P > Aircraft batteries are all made of lithium batteries. Working in low temperature environment, the internal resistance of batteries will increase, which will lead to the decrease of discharge capacity, and then the maximum thrust of aircraft may be insufficient, making it difficult to maintain stable flight.

Suggestions for battery use in winter:

1. Before flying, be sure to fully charge the battery to ensure that the battery is in a high voltage state;

2. preheating: fully preheat the battery to above 2°C (the battery temperature can be checked through the app);

3. Keep the plane hovering for about 1 minute after take-off, so that the battery can use internal heat to fully preheat itself;

4. operate the swing gently to avoid flying in a violent posture;

5. When the weather is cold, the flight time may be shortened, so it is suggested to pay attention to the battery power of the aircraft in real time during flight;

6. It is recommended to return early to avoid returning with low battery.

low temperature not only affects the flight performance of aircraft, but also affects the mobile equipment and handling stability. Therefore, heat preservation measures must be taken during flight.

Heat preservation of mobile devices:

Most mobile devices use built-in lithium batteries, which are similar to the principle of aircraft batteries. In low temperature environment, the power consumption of mobile devices increases obviously, and the battery activity decreases, which is prone to abnormal phenomena during use. When flying, it is necessary to keep the mobile device warm, and pay attention to the phenomenon that the mobile device may turn off automatically and the app flashes back.

Hands heat preservation:

In winter flight, if your hands are exposed to cold air for a long time for flight control, your fingers may be stiff due to low temperature, resulting in slow control response. Therefore, hands should be kept warm before flying, and long-term flying should be avoided to prevent hand frostbite.

Snow is an important shooting theme in winter aerial photography, but if you want to take beautiful scenery photos of the world wrapped in silver, you should pay more attention to the adjustment of exposure and tone.

increase exposure:?

With regard to underexposure, there is a proper term "white plus black minus" in photography, that is to say, on a white background, the light metering system of the camera thinks that the light is more than the actual situation, and the photos taken will be underexposed. Therefore, when shooting snow scenes, we need to appropriately increase the exposure to make the exposure of snow scenes normal and appropriate.

Adjust the white balance:

The automatic white balance of the camera is easy to get the correct color tone in sunny days, but in snowy days, the most accurate effect can't be obtained. If the automatic white balance is used, the photographed snow scene will be gray and look lacking in transparency. Therefore, it is necessary to adjust the white balance of the camera according to the environment at that time, so that the color of ice and snow in the photo is closer to the white seen by the naked eye.
