2.3.5 National oversight of aircraft operator de-icing / anti-icing
operations
The oversight of aircraft operator de-icing / anti-icing operations are generally performed via
the review and approval by the NAAs of each airline’s Operations Manual (OM), which shall
include details of the winter operations plan and any relevant procedures for the flight crew.
Figure 27 graphically illustrates the responses provided by aircraft operators on the methods
for the approval of the winter operations programme for de-icing / anti-icing.

Figure 27: National Authority approval of winter operations plan/programme for deicing
/ anti-icing of aircraft on the ground
The winter operations programmes (incl. flight crew training) are audited – as shown in
Figure 28 – usually internally by the airline quality department (82%), and only in very few
cases directly by the NAAs (9%).
