What to do before you fly

  • Drone, propellers and battery: check them before every flight.
  • Weather and wind: check the forecast and stay within the wind limit in the drone manual.
  • People and obstacles: pick an open spot and look at what is around you: people, wires, trees, buildings.
  • Airspace: check whether the point is in a restricted geographical zone. In Romania, the zones are published by ROMATSA.
  • Approval: if the zone requires an approval, get it before you fly. For filming or photography in a restricted zone you also need the approval of the Ministry of National Defence.

What to know about this class

Specific to class C4

  • You fly only in subcategory A3.
  • You fly only where you reasonably expect not to endanger uninvolved people, and at least 150 m from residential, commercial, industrial or recreational areas.
  • The drone has no automatic flight modes, apart from stabilisation and lost-link assistance.
  • The class requires neither remote identification (Remote ID) nor a height limiter, so you keep track of the 120 m limit yourself.

General rules for the whole Open category

  • You keep the drone in your visual line of sight at all times, with the naked eye (VLOS). An observer can help you.
  • The 120 m limit is measured from the closest point of the ground below the drone. Exception: near a structure taller than 105 m, the flight may go up to 15 m above it, within 50 m of it, only at the request of whoever is responsible for the structure.
  • You do not carry dangerous goods and you do not drop anything from the drone.
  • In Romania, the Open category needs no authorisation from AACR. Restricted geographical zones and the Air Code still apply.

Registration and pilot training

  • When to register: if the drone weighs 250 g or more, or has a camera or another sensor able to capture personal data.
  • Where: once, as an operator, in the country where you live. In Romania, on the AACR portal: uas.caa.ro.
  • You display your operator number on the drone.
  • Training: an online course and an online A1/A3 theory exam (40 questions, at least 75% correct). In Romania, the exam is run by AACR on uas.caa.ro.
  • Carry proof of the exam when you fly. It is valid for 5 years.
  • The minimum pilot age is 16, except when flying under the direct supervision of a pilot who meets the requirements.
  • Insurance: AACR requires it for drones over 20 kg.
