Before an  aircraft can take off, it has to get cleared of snow and ice to ensure safe flight characteristics.  A mixture of de-icing fluid and water is used to remove contamination. During winter precipitation a protective layer (anti-icing) is applied afterwards to prevent further adhesion of snow and ice. The de-icing is done with special equipment and  with trained and  qualified personnel at the gate  position or the designated remote  de-icing pads.


In Frankfurt, we use two different  types of fluids that differ in their composition of glycol and water, the addition of thickeners and thus their attributes. Our de-icing fluid type I contains 80% glycol, no thickeners and is a thin liquid. It is suitable for de-icing but only offers a limited protection against refreezing. Type I always has to be mixed with water, the mixture  is produced  proportional to the outside air-temperature. Our de-icing fluid type IV contains 50% glycol and the addition of thickeners improves the adhesion to the aircraft  surfaces. That way, winter precipitation can be absorbed and liquified, that results in a better holdover time. The fluid can be applied – depending on the required protective effect – in predefined dilutions (50% or 75%) or pure. The decision which fluid is used happens situationally, depending on the  weather situation, contamination or the  location of the de-icing.



Step 1

The decision if an aircraft depends on the pilot. There are two possibilites for the deicing request: Either the pilot contacts us during the planned off-block-time via the datalink in the cockpit or informs  us about the de-icing requirement over the flight radio frequency 121.985 MHz.

After the inquiry we create an order in the Aircraft De-icing Center (ADC)  and inform the pilot about the estimated de-icing time. The de-icing process will be done either at the current position  of the aircraft or at one of the Remote Deicing Pads.  

At the planned time the N*ICE team  arrives  at the  cleared position with the de-icing vehicles (position de-icing) or  an airplane can  taxi to the special de-icing position located near the departure runway (remote de-icing).  


Step 2

At the planned time, N*ICE is ready on the de-icing position  

For the de-icing, we deploy our vehicles with NAD-technology that meet all the requirements for a fast and sustainable de-icing and are also predestined for the usage  of large aircrafts e.g. the A380.  

Existing signs of ice will be removed  with the special de-icing fluid. Additionally, we apply a  "protective layer", which prevent refreezing of the aircraft surfaces, if requried. The de-icing procedure takes approximately 10-15min.

Step 3

After the completion of the de-icing process, the ICEMAN transmits the "Anti-Icing Code" to the cockpit.

The aircraft is now ready to  taxi to the runway, whether it has been de-iced at the parking position or on one of our de-icing pads.  

The "Anti-Icing Code" informs the flight crew  about the required concentration and type of de-icing fluid used, as well as start time of Anti-icing.  The code confirms that the aircraft is free of snow and ice.


For carriers with over-night-stands at Frankfurt Airport, N*ICE offers the so-called Pre-Deicing Service:

In case of weather conditions likely leading to the necessity of aircraft de-icing, N*ICE operates the de-/anti-icing before any other ground handling activities around the aircraft begin.

To request the pre-deicing service, the conclusion of a contract is required. Please contact us for further information.
