(a) Release the EXTRACT pushbutton switch (the OVRD legend comes on).
(6) Put a warning notice to tell persons to remove snow from their shoes and clothes before they go into the aircraft. This is very important in the cargo compartments. If there is ice or snow on the latches, this can cause defective operation of the cargo loading system.
R (7) Apply the ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-001) or ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-003) or ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-004) to all the surfaces of the aircraft with the mobile equipment but do not apply the fluid on: - the APU air intake, - the ram air inlets, - the landing gear doors, - the engine cowls and air intakes, - the outflow valve air outlet, - the pitot probes, - the temperature sensors, - the ice detection probes, - the static probes, - the AOA sensors.
R R R (8) Do not put too much de-icing fluid in the rudder, elevator and aileron servo-control areas. Use sufficient fluid to remove the ice and the snow.
NOTE : If the layer of snow is too thick, remove most of the snow____ with brooms. (Use brooms with soft bristles so that you do not damage the skin of the aircraft).
R R R (9) Make sure that there is no ice frost or snow in the engine air intake, all the air inlets and outlets and the engine fan blades. This includes the rear side of the engine fan blades.
