Part 3/11:
As the 747 climbed to 1,000 feet, a standard right turn was initiated, but the captain noticed a severe malfunction: his Attitude Direction Indicator (ADI) had frozen. In a timely manner, after the aircraft's systems caught the discrepancy, the captain handed control to the first officer while troubleshooting began. Upon further inspections, the captain switched the control of the ADI to an alternate source, allowing the instrument to function correctly for the remainder of the flight.
