2.3.3
Deicing / Anti-icing the Wings, Stabilizers and Fuselage
Note
Deicing / anti-icing can be done as a one or two step process. Step one is to deice the
aircraft and step two, if necessary, is to anti-ice the aircraft before takeoff.
The one step process applies heated deicing fluid to remove contamination and also provide
some anti-icing protection.
The two step process first applies the heated deicing fluid to remove contamination. The
second step applies the anti-icing fluid to the critical surfaces. The second step must be done
before refreezing occurs.
shows the areas essential for deicing and
spraying anti-icing fluid.
1
Manually remove all contamination from the aircraft structure.
2
If there is ice accumulation present in the control surface cavities, spray deicing fluid from
the top of the wing.
3
Deice the stabilizers surfaces in a similar manner to the wing.
4
The area adjacent to the elevator balance horns and the horizontal stabilizer should be
thoroughly inspected.
5
Deice the fuselage from the top centerline then outboard and downwards.
6
If necessary, use type I deicing fluid to aid the removal of the contamination. Apply the
deicing fluid:
−
In an even layer
−
With the spray direction from the front to the rear
−
Symmetrically on both sides of the aircraft
−
Start on the left wing, from the leading edge tip then inboard and rearward
−
On the stabilizers, from the leading edge tip then inboard and rearward
−
On the right wing, from the leading edge tip then inboard and rearward
−
On the fuselage, from the top centerline then outboard.
7
Remove any deicing fluid from the windshield and nose area in front of the windshield.
8
If necessary, apply the anti-icing fluid:
−
In an even layer
−
With the spray direction from the front to the rear
−
Symmetrically on both sides of the aircraft
−
Start on the left wing, from the leading edge tip then inboard and rearward
−
On the stabilizers, from the leading edge tip then inboard and rearward
−
On the right wing, from the leading edge tip then inboard and rearward.
