Feature Article: Illusions - Natural Illusions
Rain
Rain gives the illusion of being higher than you actually are.
Combined with haze, you will fly lower approaches during rain.
Visibility
Low visibility can cause the illusion that things are further
away. Entering a fog during descent will give an illusion of pitching
up.
Wind
An updraft can cause such vertical sensation as to cause the pilot
to put the nose of the aircraft down. He senses a climb where
the attitude of the aircraft has been level. Avoid the weather
conditions that can cause illusions. Believe your instruments.
Get an instrument rating.
Health
Illness, medicine, alcohol, fatigue, or hypoxia will make susceptibility
to an illusion more likely. It takes very little to cause disorientation
