2.1.3 Type I Fluids availability per Winter Zone
The proportion of aerodromes providing Type I fluids per Winter Zone, displayed in Figure 3,
further explains the current utilisation of de-icing and anti-icing fluids. Italy, Spain, and South
of France, situated in Zones 1 and 2 (less than 10 snow days per year) have a different
approach on the fluids provision at their aerodromes. While aerodromes in Spain and South
of France mainly conduct “de-icing only” operations with Type I fluids, Italy mainly conduct
de-icing / anti-icing operations mainly with thickened fluids only. The aerodromes within Zone
3 are for most part in the UK – a country with a low Type I fluids availability ratio.
Zone 4 and 5 aerodromes (situated in e.g. Germany, Austria, the Benelux, Poland, Romania,
Bulgaria etc.) have a Type I availability ratio close to the overall average. It can be observed
that, the ‘New’ Member States, such as Poland, Romania and Bulgaria, have a low Type I
availability ratio. This may be explained by the fact that these aerodromes had already
invested in de-icing / anti-icing infrastructure, facilities and equipment prior to the safety
issues with thickened fluids being raised.
Zone 6 aerodromes, mainly located in Nordic countries, make great utilisation of Type I
fluids, mainly for use as a de-icer instead of using thickened fluids for that purpose.
