(ADF = Aircraft De-icing Fluid, glycol based)

 

Aircraft de-icing fluid (ADF)

The de-icing fluid used in Bern is provided by Clariant. This includes one type I (red) ADF and one type II (yellow) ADF. Type I is used alone when there is no precipitation. For precipitation in the form of rain, snow or hail, type II ADF is used as well. The type II ADF serves to protect the aircraft from precipitation for a specific time period, defined in a table, dependent on outside temperature, type of precipitation and concentration in use. Type I ADF is applied hot (approx. 80° C) and performs the actual de-icing. The glycol in the de-icing fluid creates a protective layer on the aircraft which lasts until take-off. In the Tempest vehicle, type II ADF is only applied cold in a 100% concentration and serves only to stop the aircraft from re-freezing. In the Polynia vehicle, only type II ADF is used. This is applied warm and in concentrations of 100%, 75% and 50% (ADF/water), depending on weather and outside temperature. The Polynia de-icing truck is only a back-up vehicle for the Tempest. Although aircraft de-icing fluids are biodegradable, they are mopped up at Bern and incinerated.

Snow clearance

The two runway clearing machines are normally deployed together to clear snow from the runway. The clearance strategy employed has been adapted which enables the most efficient clearance of the runway. Clearance takes place at speeds of up to 40 km/h. Snow ploughs and brushes are not suited to higher speeds. Once the runway has been cleared, snow is cleared from the taxiways and, if necessary, from the apron. A special method is also employed here. The snow blower is used as soon as the snow has reached a height at which, for safety reasons, it has to be cleared. Ramp Control is responsible for the quality of clearance work and the observance of regulations and also determines the measures necessary to ensure that vehicles can land and take off safely.

Runway de-icing fluid

Biodegradable. Used to ensure safe taxiing, landing and taking off of aircraft on the runway, taxiways and apron. Ramp Control determines the need to use runway de-icing fluid, normally after snow clearance and only when the surface requires it. Bern currently deploys GEN3 from LNT Solutions Ltd. This material has been approved by the Canton of Bern’s Office of Water and Waste. The runway de-icer can also be deployed preventively, providing a protective period for the surface area sprayed depending on the weather condition.
