German union calls New Year strike at Germanwings
Tougher mental health checks and better medical examinations have been proposed for pilots following the deliberate crash of Germanwings flight 9525.
Flight 9525 co-pilot Andreas Lubitz, who deliberately crashed the plane last year, trained at the Airline Training Center of Arizona.
All 150 people aboard died one year ago when co-pilot Andreas Lubitz steered the plane into a mountain.
Families of crash victims are reportedly planning a lawsuit in the U.S. where Lufthansa, which owns Germanwings, trained its pilots.
On March 24, 2015, Germanwings Flight 9525 was deliberately crashed into the French Alps by its co-pilot, leading to the death of all 150 people on board.
Andreas Lubitz, who is believed to have deliberately crashed Flight 9525, also told a doctor he had insomnia, according to a report.
The recommendations come in the wake of the Germanwings disaster that killed 150 people in March.
The findings reportedly give rise to speculation that the 27-year-old pilot may have considered other means of committing suicide.
A French prosecutor said doctors in the weeks leading up to the deadly crash had reservations about Andreas Lubitz's psychological state and ability to fly.
A lawyer for some of the families said that this would provide "closure" to the relatives of the victims.
Authorities have said they believe Lubitz, a 27-year-old with 630 hours of flying experience, destroyed Germanwings Flight 9525 on purpose, killing all 150 people on board.
The victims' bodies from the Germanwings crash over southern France in March have all been identified and can be sent home to their families, according to the prosecutor in Marseille, France .
The BEA report cited cockpit data to reveal co-pilot Andreas Lubitz had rehearsed a controlled descent on a previous flight.
The Germanwings co-pilot suspected of deliberately crashing a plane in the French Alps in March, killing all 150 people on board, practiced a descent on the previous flight, Bild newspaper said.
Lufthansa recently earmarked $300 million to cover the costs of the March 24 crash.
Lubitz researched diuretic drugs online before he reportedly locked flight captain Patrick Sondenheimer out of the cockpit and crashed the plane on March 24.
Lufthansa said Monday that it didn't have to report Andreas Lubitz's past depressive episode, given new regulations in 2013.
