Part 3/8:
Around seven hours into their flight, the first officer began briefing the crew on the approach to Bangkok amidst turbulent weather. Rain was reported at the airport, and the decision was made to land on runway 2-1 left instead of the originally planned runway 2-1 right. This switching was unusual and placed them in a context requiring increased caution. The new runway was both narrower and had a steeper glide slope, a modification with significant implications for landing safety. However, the crew's chosen settings—auto brake 2 and flaps at 25 degrees—were viewed as standard procedure.
