When a plane goes down in the ocean, the black boxes aboard have enough juice to ping for thirty days. The pingers on flight data recorders AKA “black boxes” last a minimum of 30 days. After 30 days, the devices are still active, but the sound on which searchers hone is expected to die out. The pinger is located by a “pinger locater,” a device that listens for the sound of the black box. It is towed within the search area but it’s listening radius is usually around 2 miles. The pinger’s sound is not very powerful, and the pinger is towed at 3 knots.
After AirFrance 447, legislation was underway to increase the battery life to 90 days. The technology exists, but because implementation of that transition has been slow, EgyptAir MS 804’s pinger battery is expected to expire at around 30 days.
Several different alerts on this plane went off immediately prior to the plane disappearing from the radar, including 1) issues with the windows on the co-pilot’s side of the plane; 2) two smoke alerts, the first one “SMOKE LAVATORY SMOKE” at 00:26 a.m. local time; 3) the second one “AVIONICS SMOKE” at 00:27 a.m. The second alert refers smoke in the avionics bay, which is located below the cockpit, and is where the electronics are housed.
This is also the same plane that was vandalised two years ago at Cairo Airport. In Arabic someone, presumably Cairo Airport workers, wrote on its belly, “We will bring this plane down.”
It is a special concern that the plane had flown to Eritrea.
The US State Department has a standing travel warning for Eritrea, and is quoted as saying “security at the Asmara airport ‘can be unpredictable,’ and had a ‘lack of efficiency and consistency” in screening passengers.'”
“on 2016/06/01, Egypt’s Civil Aviation Authority reported “Laplace” located pings presumably from one of MS804’s black boxes. The vessel “John Lethbridge” of DOS will be joining the search team to retrieve the black boxes. The BEA (FR)confirmed that Egyptian Authorities have confirmed a “signal that may come from one of the recorders” of flight MS-804. The BEA did NOT confirm that a black box has been located.”
Before the wreckage was located off Greece’s Karpathos Island, search and rescue services picked up the ELT signal around 8:25, four hours after dawn. Greece reported two red and white plastic objects floating in the sea, and two orange objects, apparently life vests. Civilian ships are heading into the area to assist. France is assisting the search, with ships and aircraft. Several bodies were found floating in the area, according to RT.
The EgyptAir A320 disappeared May 18 over the Mediterranean.
When planes cross from one country’s airspace into another, the Air Traffic Control transition at those points is called the ‘hand-off.’ The crew was engaging with Greek ATC but when they attempted to hand the aircraft off to Egypt ATC, the crew made no response.
EgyptAir released that the crew was comprised of the captain, first officer, five cabin crew and three sky marshals. The passengers included 30 Egyptians, 15 French, 2 Iraqis, 1 British, 1 Belgian, 1 Kuwaiti, 1 Saudi, 1 Sudanese, 1 Chadian, 1 Portugese, 1 Algerian and 1 Canadian. The 56 passengers included three children.
Journalists have been barred by Airport security from the area in the Cairo airport where family and friends of the passengers are waiting.
Eurowings flight EW-152 had to divert and make an emergency landing at Paris Orly Airport, Orly, France, on March 25.
The Boeing 767-300, flying from Cologne, Germany to Bridgetown, Barbados, was mid-air above France when the crew reported a technical problem with the APU (Auxiliary Power Units), prompting the plane to divert.
An Air France flight had to make an emergency landing at the Moi International Airport in Mombasa, Kenya, on December 20.
According to the Police Spokesman Charles Owino, “It requested an emergency landing when a device suspected to be an explosive was discovered in the lavatory.” The plane was heading from Mauritius to Paris at the time.
The plane landed safely. All 459 passengers and 14 crew members remained unharmed.
Owino confirmed that an investigation has been launched to “determine if the device had explosives.”
