Great video by Air Safety Institute about how it feels when a VFR pilot flies into IMC. This is GA's most fatal type of weather-related accident yet pilots continue to take the risk. The decision to fly into IMC gives them only 178 Seconds to live. You simply can't fly by the seat of your pants in IMC. Just don't do it!
The average time a pilot can expect to live after experiencing spatial disorientation has been studied by researchers at the University of Illinois in 1993. They put twenty students into simulated instrument weather. All went into graveyard spirals or rollercoasters within 20 to 480 seconds. The average time was 178 seconds - just two seconds short of three minutes.
