  • C0 (under 250g0)
  • C1 (under 900g)
  • C2 (under 4kg)
  • C3 (under 25kg)
  • C4 (under 25kg)
• Specific Category
  • C5
  • C6

Check Dronemaps

• Information specific for the operation
  • purpose of the operation and type
  • Estimated duration
  • Crew information (including pilot)
• General UAS information including takeoff payload
• Location and date
• Verification of the flight zone
• Weather forecast
  • Temperature
  • Humidity: water absorbs radio signal propagation
  • Wind speed
  • Flighting altitude: at higher altitude the air is less dense which results in loss of lift
  • visibility distance
  • Kp-index 2 (geomagnetic malfunction): In GPS mode with a MAX. of 4.

The two emergency situaions:

• Loss of link
• Fly away

some extra infomation to consider:

• What is the flight path?
• What might be encountered on the way?
• What are the possible emergency landing zones?
• What is the protocol to be followed in case of unexpected situations?

On temperature:

• Diurnal cycle
