Dream on fire

According to the Flightblogger, one of the 787 aircraft had to land due to a fire in the electronics bay. It was able to land safely, however a fire and smoke onboard of an aircraft is a very serious incident. A strange thing is the deployment of the RAT. This is the Ram Air Turbine. An aircraft need a lot of electrical power. This power is generated by the engines, however when all engines have failed, a small propeller is deployed outside the aircraft that is driven by the head wind to provide electical power to the absolute minimally necessary equipment). This generator is called RAT. It’s deployed as a last-resort-measure … so it will be interesting to read in the official incident report about the situation.
