Things you need to know AeroDAY’14 Mai the 03rd 2014 Malaysia Airlines flight MH370 What went wrong ? • Every Aircraft has a radar signature (even birds!! ) • Radars can “see” objects in the sky and assign for each a point in the radar scope without any identification. • Radar operator can monitor only the position and the speed of aircrafts in regular time lapse. • Used today for emergencies and training. Primary surveillance radar

Why Hijacking can be the cause ? • Two passengers have boarded with 2 stolen passports. • Systems shutdown, silent navigation. • No radio communication. • Aircraft still flying for extra 6 hours. • It’s not the first time: B737 Flight 653 in 1977.

  28. 28. 28 5. Most possible Scenario AeroDAY’14 Mai the 03rd 2014 Malaysia Airlines flight MH370 What went wrong ? Electric system failure.. • Electric system failure caused by wire sparks ( or fire ) can explain the shutdown of transponder and the malfunction of ACARS, radios.. • Navigation systems and MFD screens could be disabled too. • Dark night without a moon has conducted to fly the plan in blind configuration and cause “Vertigo” to pilots.

  45. 45. 4 5AeroDAY’14 Mai the 03rd 2014 Malaysia Airlines flight MH370 What went wrong ? “A series of Human Factor problems forms an error chain. If any one of the links in this chain had been broken the incident may have been prevented. It might be done by building in measures/defences, which may not permit an error at one or more of the stages” - James T Reason -
