France BEA's aviation investigators on Friday said the second black box recovered from the Germanwings crash site in the southern French Alps confirmed that co-pilot Andreas Lubitz had deliberately crashed the plane, reports FRANCE 24.
"A first reading shows that the pilot in the cockpit used the automatic pilot to put the airplane on a descent towards an altitude of 100 feet," BEA investigators said in a statement.
"Then several times the pilot modified the automatic pilot settings to increase the speed of the airplane as it descended," it added.
Authorities found the second black box, which contains technical flight data, on Thursday after a gruelling nine-day search in difficult mountain terrain.
Data from the first black box, which records conversations in the cockpit, suggested that Lubitz, 27, locked his captain out and then deliberately set the plane on a deadly collision course with the mountains.
