2.12. Fuel tanks, fuel and engine oil

Gasoline has a significantly higher energy density than even the best batteries and is still unavoidable when drones require long reach or great endurance. Since great reach does not make a lot of sense when visible line of sight from pilot to drone is a requirement, drones with gasoline engines might require special permits or waivers to be used to their full potential.

Due to the inflammability of fuels they increase the risk of fire or environmental pollution when they crash.

Risks

  1. Fires caused by drone accidents.
  2. Damage caused by environmental pollution caused by fuel spillages.

Audit Steps

  1. Verify that fuels and oils are stored safely and that access controls are adequate.
  2. Ensure that emergency response equipment includes fire extinguishers.
  3. Assess the specific risks caused by gasoline engines and evaluate if these risks could not be eliminated by using drones powered by electric motors.
  4. Review monthly fuel consumption and assess the reasonableness based on mission numbers. Unexplained high consumption could be due to flying activity which is not properly recorded.
