Let's examine the attitudes given:

• Macho ('I'll show them'): A mindset characterized by exaggerated masculinity, toughness, assertiveness, and a strong desire to display dominance or control. This attitude is hazardous for aviation as it may lead to risky decisions.
• Impulsivity (‘I must do something quick!’): A tendency to act quickly without careful consideration of the potential consequences. Individuals with an impulsive attitude may make decisions or take actions based on immediate impulses rather than thoughtful deliberation or planning. This attitude is hazardous for aviation as it may lead to quick but wrong reactions.
• Infallibility: A mindset or behavior where a person believes they are always right and incapable of making mistakes. This attitude is hazardous for aviation as cross checking the decisions and actions in the cockpit might be neglected and errors might remain undetected.
• Synergetic attitude: An attitude that decisions should be taken by the captain with the help and participation of the other crew members. When this attitude prevails in the cockpit, the captain motivates the crew, supports team work and clearly communicates intentions and required standards. This attitude is ideal in aviation.
