       If you plan on flying North of the freezing level, read Rick 
Durden's column
  in Avweb's Pilot Lounge "Of Martinis, Ice and Tailplane Stalls"
             (http://www.avweb.com/articles/lounge/tpl0042.html).
  "...> reports that you should recover in tried-and-true fashion if the 
wing stalls.  If the tailplane stalls, however, the required control inputs 
will  be just the opposite and the control forces may require more 
strength than you possess."

  Why is this special for LNC2 drivers?  Because we have the sharpest 
tailplane  leading edges of any aircraft and flaps that generate an 
enormous nose down  pitching moment when deployed.  After reading the 
article, here are some other considerations:
  Most of us have painted much of our airplanes in white, including the 
wing leading edge -- a good idea for dealing with the summer heat, but 
making it  More difficult to detect the the beginnings of ice 
formation.  This is  especially true since we sit somewhat behind the wing 
leading edge and ice formation starts out of sight.  However, most everyone 
has used a dark color  feature out by the wing tip and this has been useful 
in recognizing rime ice  formation as the wingtip leading edge begins to 
fade into the same white  color as the rest of the wing.  Make that wing 
tip part of your scan when  flying in cold clouds. I've never had much 
flexibility in my neck and age has not improved my  ability to see things 
behind me.  So, this winter I am installing a rear view  Mirror on the 
interior of the canopy to see the tail leading edge thru the back 
window.  I have dark tips there too and I want to see any tail 
ice  formation so I can take action immediately.

  PS I like ice in my gin, not on my wing!
