"On January 23, 2003, a Singapore Airlines (SIA) Boeing 747-400 experienced a complete loss of information on all six integrated display units (IDU) on the flight deck instrument panels while in cruise flight from Singapore to Sydney, Australia. The pilots flew the airplane for 45 minutes using standby flight instruments while they communicated with SIA maintenance personnel about the problem. SIA maintenance personnel advised the flight crew to pull out then push back in (or cycle) the circuit breakers for the EFIS/EICAS interface units (EIU), which returned the IDUs to normal operation. The flight continued to Sydney and landed without further incident."U.S. National Transportation Safety Board Recommendations A-03-55 and A-03-56 Μια ακραία θεώρηση της διεργασίας του ελέγχου είναι η παρακάτω:
