There are five types of attitudes that can be considered “hazardous”. It is these attitudes that make us do things that have consequences that outweigh the reward.
Someone who “breaks the rules”. The thinking of “I know better than the boss” falls under this category.
Example: Not following SOP or the CAR.
Reacting before spending some time to think about your actions.
Example: Skipping items in a checklist because you’re in a rush. Not doing a HASEL check because you’re pressed for time.
“Oh, nothing’s going to happen to me” or “Bad things always happen to other people”. Not thinking your actions will effect you at all.
Example: Someone who thinks they can do anything because they’ve been flying for many years.
Doing things you wouldn’t normally do to fit in. Showing off to earn respect or impress someone.
Example: Trying to impress your captain by attempting a landing you’re not comfortable with. Impressing friends by doing acrobatics when you’re not trained/certified.
Giving up when you know you’re right. This usually happens when you’re challenging someone of authority or above you.
Example: After telling the captain a couple of times that something doesn’t look right, and he dismissing you each time, you give up.
At least one of these attitudes can be found in each aviation accident.
