Emotional response in an aircraft is dangerous. Fear kills.
Fear triggers the fight or flight response and it does effect your ability to respond physically. Your body functions change. There is a loss of blood and oxygen flow to the non essential fight or flight organs like stomach, kidneys. Some peoples bladder empties so they can flee. The eyes are effected. Your eyes loose focus on things the mind doesn’t believe are a danger. So you can only focus on the thing you believe is the threat.
This is why training so so important. Pilots are taught to understand the aircrafts systems so when something does go wrong, they can work the problem without fear causing them to loose the ability to see everything happening and respond.
It is believed now that pilots not experiencing full stalls and spins is creating pilots that fear them. A stall or spin isn’t something to fear, it should be understood. This way you will avoid it, and if by some weird chance you do believe there is a stall or spin you will react properly.
