Ready For A Chill?
For those of us who have "hit the boots" (or the equivalent
system on your favorite bird) a few times in the last few days due
to the ever-present seasonal 'charms' of in-flight icing, we
thought a series of short tips from Cirrus Design's Scott Winter
(yes, that IS his real name) might help us all to consider some of
the realities of this time of year. So... here is the third of
seven tips for dealing with icing. Y'all be careful out there!
Icing Aero-Tip #3: Escape Options
Climb
When warmer temperatures can be reached aloft. Make sure cloud
tops are known and attainable before attempting to climb. Icing is
often worst in cloud tops. Remember once you are on top of the
clouds, it is possible you may have to descend through the clouds
and icing conditions into your destination.
Descend
When warmer temperatures or clear air are below. Be aware of
cloud ceiling and minimum enroute altitudes prior to choosing this
escape method.
Continue
When the aircraft will exit icing conditions expeditiously. This
should never be the last option.
Divert
When conditions enroute are worse than forecast. Check weather
at all available alternate airports along your route of flight, and
always know where you will choose to go.
Return
When conditions after departure are different or worse than
forecasted. Monitoring the outside air temperature (OAT) gauge on
departure will assist the pilot in forecasting any icing that may
be up ahead. If the OAT is colder than forecast, it is likely that
other parts of the forecast may be incorrect as well.
Declare an Emergency
When ever the safe outcome of the flight is in doubt. Icing is a
legitimate emergency to deviate from your clearance.
About Scott Winter
At the time that this series was authored, Scott was a member of
the Flight Standards Department at Cirrus Design Corporation in
Duluth, MN (one of those places that see more than its fair share
of icing encounters). Born and raised in Milwaukee, WI, he
discovered his passion for aviation at an early age. After
obtaining his Private Pilot Certificate prior to his senior year in
high school, he attended Minnesota State University, Mankato (MSU)
and graduated with a Bachelor's degree majoring in Professional
Flight. In December 2006, he completed his Master's of Science
degree from MSU spending time focusing on aviation weather,
scenario-based training, and visualization techniques to enhance
the methods used to educate aviators.
