Key Findings of the Investigation
The investigation into TransAsia Airways Flight 222 revealed several critical findings. One of the primary causes identified was the pilots' decision to continue the approach below the minimum descent altitude (MDA) despite poor visibility and adverse weather conditions. The MDA is the lowest altitude to which a pilot can descend on final approach without visual reference to the runway. The investigation found that the pilots continued their descent even though they did not have the required visual cues, increasing the risk of a controlled flight into terrain (CFIT) accident. Another significant finding was the crew's poor crew resource management (CRM). CRM refers to the effective coordination and communication among the flight crew members. The investigation revealed that there was a lack of effective communication and coordination between the captain and the first officer, which contributed to the errors in decision-making. The pilots also did not adequately monitor the aircraft's instruments, leading to a deviation from the intended flight path.
