Deicing/Anti-icing Fluid
Application Guide Nov 2012 – Rev. 4
This guide is intended to assist deicing/anti-icing fluid application staff only and is not a substitute for Embraer and/or operator’s
manuals. Deicing/anti-icing fluid application shall be accomplished in full accordance with Embraer AMM TASK 12-30-01-860-801-A
and RAMP 12-30-01/201, AOM, and/or operator’s manuals. This revision supersedes all previous ones.
Be aware of deicing/anti-icing fluid holdover time expiration. Refer to fluid manufacturer’s Specification.
EMBRAER recommends two-step procedure whenever possible to prevent fluid residue accumulation
A. FUSELAGE
● Spray along fuselage top centerline and then outboard, letting the fluid cascade down and across the windows.
B. WINGS
● Spray the fluid from the wing tip inboard to the root, sweeping from the leading edge to the trailing edge.
Tactile Inspection
Inspection by touch is required if it is not possible to be certain that all forms of snow and ice have been removed by
making a visual inspection.
DO NOT APPLY FLUIDS DIRECTLY TO THESE POINTS

● Spray fluid from the surface tip inboard to the root, sweeping from the leading edge
to the trailing edge. Refer to the figures below for proper spray direction to avoid APU fluid ingestion.
Straight spraying Up to 45-degree spraying Cross spraying Back spraying Side spraying
Recommended Permitted Recommended Not Recommended Not recommended
D. VERTICAL SURFACES/WINGLETS
● Start at the top and then work down. Apply the fluid
at an angle of less than 45 degrees (Reference: fuselage centerline).
E. ENGINE AND APU
● Do not point the spray of deicing/anti-icing fluid directly into the engine or APU inlets, exhauts, engine thrust
reversers, scoops, vents, and drains.
● In case of either snow or ice accumulation in the APU air inlet and on surrounding area, refer to AMM TASK 12-30-
01-860-801-A for instructions to remove it mechanically.
CAUTION:
● MAKE SURE THE APU INLET AREA IS CLEAR BEFORE YOU START THE APU.
● APU OPERATION IS NOT RECOMMENDED DURING THE AIRPLANE DEICING/ANTI-ICING PROCEDURE.
