2.1.5 Impact on affected traffic of Type I Fluids unavailability
The Figure 6 displays a qualitative “risk factor”, based on the total number of affected aircraft
traffic at aerodromes not providing Type I fluids and the weather zone (number of
movements of affected traffic at aerodromes not providing type I – multiplied by the weather
zone number, e.g. 1 for “Zone 1”). However, a different weighting of the parameters may
have led to slightly different results, according to this key indicator; the most affected
countries by potential safety issues related to the non-availability of Type I fluids are United
Kingdom, Poland, Italy, Austria, Germany and Romania.

Risk factor based on total affected traffic
Figure 6: Impact on affected traffic of Type I Fluids unavailability (based on number of
affected traffic movements at aerodromes not providing Type I fluids and number of
snow days)
The Figure 7 displays a similar qualitative “risk factor” as the previous one, but based only on
the number of aerodromes not providing Type I fluids and the number of snow days. In this
case, the risk factor does not take the traffic volumes into account.
