What Is a Known Error?

False hypothesis is an important cause of errors during the flight decision phase. Countless flight accidents have been induced. The most dangerous feature is that once the person is caught, it is difficult to correct, often it is easy to take, but it is very difficult to give up. Although in conflict with the incident or verbal warning during the flight, the pilot may still insist on the original intention and easily reject these factually correct information and advice, and only wake up when things turn irreversible. ^[1]
