The Germanwings co-pilot suspected of deliberately crashing a jet in the Alps in March practiced entering the fatal descent settings on the previous, outbound flight, investigators said Wednesday.

The changes in autopilot settings, mimicking those which crashed the jet on its way back to Duesseldorf from Barcelona some two hours later, would barely have been noticeable because the jet was already descending, investigators said.

“The first flight of the morning before the flight of the accident which was from Duesseldorf to Barcelona, after the ATC (air traffic control) had ordered the aircraft to descend and while the commander of the flight had left the cockpit, the co-pilot who was alone in the cockpit did several times actions altitude select command of the autopilot so it was a repeat (rehearsal) of the action he did on the accident flight,” Remi Jouty, director of the French BEA accident investigation agency, said.

Shortly after the aircraft had reached cruise height on the return flight on which all 150 aboard died, the captain told Lubitz he was leaving the cockpit and asked him to take over the radio.

Just over 30 seconds after the door closed, leaving Lubitz alone in the cockpit, the 27-year-old entered the instruction he had previously rehearsed, ordering the plane to descend to 100 feet on autopilot: easily low enough to crash into the mountains ahead. He then altered another dial to speed the jet up.

The findings come from examination of cockpit voice recordings and flight data taken from the aircraft’s two black boxes.

The BEA, whose investigation runs in parallel to judicial probes, will issue a final report in about a year that may include recommendations on cockpit doors and the handling of pilots’ medical records by the airline industry.
