Pitot Tube Ice

• If ice forms over the pitot tube, the airspeed indicator will be inaccurate. The pilot would still have full positive control of the aircraft.
  
  

Wing Icing

• Ice changes the shape of the wing, which reduces its lift and adds weight to the aircraft. This can create a scenario where the pilot can lose control of the aircraft.
  
  

Equipment

• Heat melts ice from the pitot tube, and many aircraft have devices on the wings to melt and break ice.
  
  

Preflight Precautions

• Most airports provide deicing services to remove ice from the aircraft prior to departure.
  
  

Flight Precautions

• If your aircraft is not capable of flying in known icing conditions, avoid flying anywhere there is visible moisture and freezing conditions.
