An Item of Safety...

This is a little dramatic, but
the point is clear.
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. 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 now 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 now 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 out of seconds.
Think
about it before you press on into marginal weather.
