have, among other things, electrically powered baggage tractors or power units. These vehicles are often positioned near aircraft, corridors, or in hangars. This poses the same hazards as specified above. This, therefore, also requires additional attention in terms of airport safety. In practice, it is advisable to locate an e-parking facility at least 15 metres from essential airport infrastructure and not underneath spaces that are used by people. It is also a good idea to install charging points at a considerable distance from airport buildings or essential equipment. Compliance with the NEN 1010 standard is a must. Ground risks and focus points for electric aircraft and ground equipement • Fire caused by thermal runaway • Formation of highly toxic flue gases due to a fire • Uncontrollable fire (Li-ion fires are very hard to extinguish, requires a lot of water) • Risk of fire propagation (to buildings or other aircraft) due to the intensity of the fire • Electrocution • Environmental pollution due to contaminated fire fighting water
• Storage of aircraft/equipment in hangars may not be covered by insurance • Damage to image
Precautions As pointed out, Li-ion fires are extremely difficult to extinguish and immersion is, to date, still the best way to prevent reignition. When it comes to aviation-related incidents, immersion is possible only in case of ‘loose’ battery packs (contrary to motor vehicles, an entire aircraft cannot be immersed). As a result, fighting the fire with only a limited amount of water is not possible. With respect to battery fires, it is important to carefully think about where such aircraft are parked. When parked outside, a location away from other objects would be best, so as to minimise the risk of the fire spreading (burn- down scenario). In closed spaces, careful thought has to be put into the distance to other aircraft and/or (combustible) materials. Preventive measures such as fire/smoke detectors and/or sprinkler systems could also be an option.
