De-icing Procedures EDDB
During cold weather, de-icing may be required around the wings and fuselage of the aircraft. In general, de-icing will be performed remotely on Apron E (see picture below). Additionally, PAD North can be used for de-icing north of runway 06L/24R.
In real life, de-icing is available between the 5th of October and the 30th of April. During this period, the following special position may be staffed by S2+ controllers:
| Login | Callsign | Frequency |
| EDDB_ICE_GND | Berlin De-Icing | 121.665 |
General Procedures
Before Start-Up
If de-icing is required, the pilot shall inform the Delivery controller before start-up approval. Additionally, ATC can also ask the pilot if de-icing is required.
Delivery will then assign a de-icing pad and confirm this with the pilot:
EJU43JB, expect de-icing at PAD13, report ready for start-up.
PAD Assignment:
In general, Delivery shall assign a de-icing PAD which allows a short taxi time from parking position to runway. If the de-icing coordinator (EDDB_ICE_GND) is online, he may inform Delivery which PADs will be in use. In real life, not all PADs will be used at the same time.
All de-icing pads on Apron E can only be used up to Code C. PAD 03 and PAD17 are approved to be used by the following aircraft types: A332, A333, A338, A339, A400, B752, B753, B763, B764, B772, B778, B788, B789, B78X, C130 and IL76. PAD NORTH 1 can be used up to code letter D (max. wingspan < 52 m).
Aircraft not suitable for a de-icing pad need to be de-iced at their parking position.
The assigned PAD shall be marked in the scratchpad by using "/ICR [PAD]" (e.g. "/ICR PAD13" for remote de-icing at PAD13). If de-icing is performed at the parking position, Delivery shall enter "/ICP" in the scratchpad ("de-icing on position).
Taxi Clearance
Apron North (EDDB_E_GND) will be responsible for all movements on Apron E or Apron 3 B. After the aircraft has arrived at the assigned PAD position, Apron shall transfer the aircraft to the de-icing coordinator when online:
EJU43JB, enter PAD13 via P2, follow the blue-dashed line.
EJU43JB, contact Berlin De-Icing on 121.665.
If no EDDB_ICE_GND is online, Apron should request the pilot to report de-icing completed:
EJU43JB, enter PAD13, follow the blue-dashed line and report de-icing completed and ready for taxi again.
De-Icing Coordinator Duties
The Berlin De-Icing will take over the phraseology tasks usually performed by the de-icing crew.
Available Fluid Types
At Berlin, fluid type 1 will be used for de-icing and fluid type 4 will be used for anti-icing. Anti-icing will add a protective fluid to the aircraft's fuselage. Anti-icing is only required if new icing could build up after de-icing (snow, freezing rain, fog, low clouds, etc.).
Holdover Times
Holdover time is the amount of time the de-icing and/or anti-icing fluid will protect the aircraft. This will differ depending on the meteorological conditions. The holdover time starts when the de-icing treatment starts. The holdover times can be determined in the tables below:
Fluid Type 1 (de-icing):
Fluid Type 4 (anti-icing):
Phraseology Example
Green: only required if using fluid type 4 for anti-icing (if required)
