Ron,
It is an old study........ Now either you would have no problem because you
are flying with virtual VFR, GPS WAAS, Terrain mapping fuselage chute and
other goodies so that you need not even look out the window OR you will die in a
lot less than 178 seconds because you ran into cell towers or
windmills.
Times have changed.

This
study was done a long time ago, but still applicable today. Just
something to think about. Get an instrument rating, and keep
current even if you don't ever plan to fly in actual IFR conditions.
If you are uncomfortable in flying in actual IFR conditions, get with an
instructor who will go with you and get some actual instrument time.
It's a LOT different than always flying with the foggles
on. Ron
178 Seconds To Live
Words to Live By
How
long can a pilot who has little or no instrument training expect to live
after he flies into bad weather and loses visual contact? Researchers at
the University of Illinois did some tests and came up with some very
interesting data. Twenty student "guinea pigs" flew into simulated
instrument weather, and all went into graveyard spirals or rollercoasters
[a tribute to the U of I flight training program??]. The outcome differed
in only one respect - the time required till control was lost. The
interval ranged from 480 seconds to 20 seconds. The average time was 178
seconds* -- two seconds short of three minutes.
Here's the fatal
scenario. . . . . . .
The sky is overcast and the visibility is poor.
That reported five mile visibility looks more like two, and you can't
judge the height of the overcast. Your altimeter tells you that you are at
1500 feet but your map tells you that there's local terrain as high as
1200 feet. There might be a tower nearby because you're not sure how far
off course you are. But you've flown into worse weather than this, so
press on.
You find yourself unconsciously easing back just a bit on the
controls to clear those towers. With no warning, you're in the soup. You
peer so hard into the milky white mist that your eyes hurt. You fight the
feeling in your stomach. You try to swallow, only to find your mouth
dry. Now you realize you should have waited for better weather. The
appointment was important, but not all that important. Somewhere a
voice is saying, "You've had it -- it's all over!"
You now have 178
seconds to live.
Your aircraft feels on even keel but your compass
turns slowly. You push a little rudder and add a little pressure on the
controls to stop the turn but this feels unnatural and you return the
controls to their original position. This feels better but now your
compass is turning a little faster and your airspeed is increasing
slightly. You scan your instruments for help but what you see looks
somewhat unfamiliar. You're sure that this is just a bad spot. You'll
break out in a few minutes. (But you don't have a few minutes
left.)
You now have 100 seconds to live.
You glance at your
altimeter and you are shocked to see it unwinding. You're already down to
1200 feet. Instinctively, you pull back on the controls but the altimeter
still unwinds. The engine is into the red and the airspeed, nearly
so.
You have 45 seconds to live.
Now you're sweating and
shaking. There must be something wrong with the controls; pulling back
only moves the airspeed indicator further into the red. You can hear the
wind tearing at the aircraft.
You are about to meet your Maker; you
have 10 seconds to live. Suddenly you see the ground. The trees rush up at
you. You can see the horizon if you turn your head far enough but it's at
a weird angle -- you're almost inverted. You open your mouth to scream
but. . . . . .
. . . .you just ran our of seconds.
Think about
it before you press on into marginal
weather.
