KUALA LUMPUR - Both the pilot and co-pilot of MH370 went through regular psychological checks as part of Malaysia Airlines' standard operating procedure, said MAS group chief executive officer Ahmad Jauhari Yahya.
He said psychological tests were conducted yearly and every six months, depending on the pilot's age.
"The tests are normally done through interviews with aviation doctors.
"Psychological tests are also conducted when we take in new pilots," he said at the press conference yesterday.
Debunking stories in the foreign media suggesting that the pilots were mentally unbalanced, Ahmad Jauhari said the company ensured that psychological tests were compulsory.
He also confirmed that the duties for the pilots were rostered.
"Each pilot and co-pilot is part of a duty roster. They don't necessarily need to know each other ... Whether they do or do not, we do not know as we have a large community of pilots," he said when asked whether Capt Zaharie Ahmad Shah and his co-pilot Fariq Abdul Hamid knew each other well prior to their ill-fated flight.
