CDS General Bipin Rawat chopper crash: What is Controlled Flight into Terrain that led to mishap - The US Federal Aviation Administration Safety defines CFIT as an unintentional collision with terrain while an aircraft is under positive control.
According to the statement of the Indian Air Force, the cause of the unfortunate accident was attributed to the unexpected change of weather conditions in the valley.
The accident was a result of entry into clouds due to an unexpected change in weather conditions in the valley. This led to spatial disorientation of the pilot resulting in a Controlled Flight Into Terrain (CFIT).
The Tri-Services Court of Inquiry constituted to probe the cause of the Mi-17 V5 accident that claimed the lives of late Chief of Defence Staff General Bipin Rawat and his wife and 12 other military personnel onboard on December 8, has ruled out mechanical failure and said that entry into clouds led to the spatial disorientation of pilot leading to the accident.
