Chapter 4 - Preventative Measures and Deicing Procedures

Exchange of Vital Information Prior to the Deicing/Anti-Icing Fluid Application

64.  Prior to commencement of the deicing/anti-icing operation, certain vital information will need to be shared and acknowledged between the Deicing Operator and the PIC, to ensure that the aircraft is treated correctly, in a safe manner, and with a safe result. In order to ensure that these basic criteria are met, the following items, dealing with the exchange of information between the pilot and the deicing crew, should be accomplished prior to commencing the operation:

  • Communication established between deicing crew and pilot.
     
  • Confirmation that brakes are set and aircraft correctly configured for the type of deicing being accomplished (e.g. engines at idle, propellers feathered, bleed systems correct, etc.).
     
  • Confirmation of the deicing/anti-icing methodology being used.
     
  • Confirmation of type of fluid(s) to be applied to aircraft.
     
  • Confirmation of fluid mixture ratio, if applicable.
     
  • Communication of any last minute cautionary or advisory information deemed pertinent to the impending deicing/anti-icing operation.
     
  • Confirmation from the Deicing Operator to the PIC that deicing/anti-icing operations are about to commence.
     
  • Time noted at the start of anti-icing fluid application. This is required by the PIC for the commencement of HOT timing. The Deicing Operator should note the time and advise the PIC.
