Flight training
Practise the figures shown below with little wind and with the sun behind you. So that you do not train yourself a preferred direction, always fly the figures to the left and to the right.
Keep a safe distance from your drone during take-off and landing. View the drone from behind during take-off and landing. In this way, the control commands are carried out analogously.

The influence of the wind on the speed over ground
Ground speed is the sum of airspeed and wind speed.
Wind turbulences
A clean air flow is only found at higher altitudes. Near the ground, obstacles, houses and forests prevent the even exchange of air masses. The wind speed, for example around buildings, can be estimated very poorly.
Dynamic upwinds or downwinds can occur on slopes. When the wind hits a slope, the air is deflected upwards. This creates updrafts which are usually not dangerous. If you fly out of this area, you lose lift!
Altimeter
An altimeter is calibrated to the pressure curve of the standard atmosphere. The altimeter measures the air pressure in hPa. At low altitude, the pressure difference of 1 hPa corresponds to 8 metres of altitude difference.
ICAO Standard Atmosphere (ISA): 15°C / 1013.25 hPa / sea level.
The further you move away from the earth's surface, the lower the air pressure becomes. This can be measured and is used to maintain the flight altitude. If gusts cause rapid changes in air pressure, this can also be seen in the drone's flight behaviour.
