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. |
