Emergency procedures

First things first: keep people safe. The drone can be replaced.

These procedures are drafts and must be approved by HVL's drone safety officer.
Urgent

Someone is injured

  1. Land the drone at once
  2. Call 113 if anyone is hurt.
  3. Give first aid and secure the site.
  4. Remove the battery when safe
  5. Notify the drone safety officer and file an incident report.
Urgent

A crewed aircraft is approaching

  1. Descend immediately and keep well clear.
  2. Land as soon as it is safe.
  3. Do not fly again until the airspace is clear.
  4. Note the time
Urgent

The drone does not respond (flyaway)

  1. Try return-to-home (RTH) or switch flight mode.
  2. Keep watching the drone and note its course.
  3. Warn people in the direction the drone is flying.
  4. Near an aerodrome: contact the tower (TWR/AFIS) at once.
  5. Note the last known position in the drone app
Serious

Critically low battery

  1. Abort the task and land at once.
  2. Choose the nearest safe landing site over a distant home point.
  3. Keep the drone away from people if it must make an emergency landing.
Serious

GNSS or compass error

  1. Be ready to fly manually (ATTI mode) — the drone may drift with the wind.
  2. Climb to clear obstacles
  3. Land and calibrate before the next flight.
Important

Uninvolved people enter the area

  1. Keep the drone away from the people and stop moving towards them.
  2. Land or hold position until the area is clear.
  3. Ask a crew member to talk to them.
Urgent

Battery or drone fire

  1. Keep your distance — smoke from lithium batteries is toxic.
  2. Call 110 if the fire may spread.
  3. Use plenty of water or sand. Do not touch the battery until it is fully cold.
  4. File an incident report.

After an incident

File an incident report as soon as it is safe. The drone safety officer follows up.
