MOSCOW (Sputnik) – The alerts from the Aircraft Communication Addressing and Reporting System (Acars) came each time the plane took off from various airports on May 19, the day of the crash, the newspaper said on Wednesday.
"This type of aircraft is equipped with several optical detectors that are responsible for capturing any smoke clearances and automatically transmit them to the Acars system to which they are connected," an airport source told the newspaper adding that the sensors can be disturbed by moisture or steam air conditioning, but have been recently "significantly improved" to avoid false alarms.
Egyptian Minister of Civil Aviation Sherif Fathi has confirmed that some debris from the plane and remains have been recovered. The search operation is still underway and involves the naval and air forces of Egypt, France, Greece and the United States.
On Wednesday, Egyptian investigators confirmed a signal from a possible recorder (black box) from the flight MS804 plane. According to the Egyptian investigation committee, the signals were received through the equipment installed on the French La Place ship, which is engaged in the search operation.
