Flying basics

TIPS for the first flight of your drone:

  • Choose a day with no wind.
  • Choose a flat surface as a starting place.
  • Keep a safe distance of 5m from the drone.
  • Start the motors, slowly push the thrust control forward and let the drone slowly climb to 2m.
  • Check the altitude and position control by releasing the thrust control, the drone should hold its position.
  • Let the drone climb to about 10m and push the position controller forward to let the drone fly away.
  • Pull the position control back to make the drone fly in your direction.
  • Pull the thrust control back to land.

 

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.

Situational Awareness

Before decisions can be made, current information and data must be gathered and interpreted. You must first get a mental picture of the situation, get an overview. Relevant information is, for example, obstacles, wind direction and airspace restrictions.

Together, these steps are called "situational awareness". This means having the "big picture" of a situation.

Situational Awareness is influenced by the following factors:

    • Personal conditions such as fatigue, workload, stress and experience with a situation.
    • Conditions such as, weather, distractions and other flying objects.
    • The complexity and performance of the unmanned aerial vehicle, the degree of automation of the processes.
 
 

 

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.
