84.  Operators need to clearly understand where they can or can not spray de/anti-icing fluids. Examples of no spray zones include, but are not limited to:

  • Engine inlets and openings;
  • APU inlets;
  • Engine exhaust openings;
  • Aircraft brakes;
  • Flight deck windows;
  • Cabin windows;
  • Passenger door handles;
  • Static ports;
  • Pitot heads;
  • Air data sensors;
  • Avionics vents; and
  • Aircraft manufacturer specified "no spray" areas.

the item with deicing fluid is acceptable (e.g. cabin windows). Consideration must also be given to factors which continuously vary with time, such as: the number and types of vehicles in use, a one step or a two step process, local weather conditions, local operational peculiarities, and so on. 
 

86.  Operators must be very familiar with any unique deicing considerations based upon aircraft type.
