Answer: Macho hazardous attitude
Explanation:
Macho hazardous attitude is the one in which the pilot has the “I can do it!” attitude.
A pilot with this hazardous attitude strives to look great and be noticed by others as a great pilot as a result they end up taking actions which may yield dangerous outcomes. Every gender is prone to this attitude which lead to silly actions in an attempt to impress others. Confident is great but too much of it may lead to this hazardous attitude.
If someone says I wish I could fly with a real pilot it is likely that you may want to prove to them that you are a real pilot by changing your mind and flying the plane in those extreme conditions eventhough you know that they pose a great threat according to your assessment of the safety risks; you might do it just to impress the customer and prove that you are a real pilot. That is a a result of a macho hazardous attitude.
