In situations where an aircraft experiences a thermal runaway, the recommended action is to secure power from the pilot side. This is crucial because thermal runaway often indicates a malfunction, where the temperature in the battery or electrical system is rising uncontrollably. By securing power, you can help prevent further escalation of the situation, which could lead to fire or explosion.

Disengaging power is essential as it removes the energy source that could potentially exacerbate the thermal runaway condition. Once power is secured, appropriate measures can be taken to assess the situation, and if necessary, implement further safety protocols such as using an extinguisher if there are visible flames, or evacuating the area.

While using an extinguisher may seem like a proactive approach, tackling the source of the energy is more crucial in preventing a serious incident. Similarly, staying close to the aircraft may seem prudent, but it is safer to establish distance to avoid harm should the situation worsen. Disconnecting the battery immediately without precautions could also pose additional risks, as it might lead to sparks in a volatile environment. Overall, securing power from the pilot side takes precedence as a key safety measure in managing thermal runaway incidents.
