1. General

These procedures are the result of discussions and developments of aircraft de-icing at Leipzig/Halle Airport in

recent years and are provided to all airlines and handling partners.

Aircraft de-icing at Leipzig/Halle Airport is conducted by PortGround Leipzig GmbH according to the

Recommendations for De-Icing/Anti-Icing of Aircraft on the Ground 27th Edition, July 2012, AEA (Association of

European Airlines); ISO 11076-11078 and SAE ARP 4737.

Only trained personnel execute aircraft de-icing. Every employee designated for de-icing is thoroughly familiar

with the respectively valid rules and regulations of the subject „ De-/Anti-Icing“.

De-icing fluid: The specifics of aircraft de-Icing fluids (ADF) are established by the International Organisation for

Standardisation (ISO).

In this season an ISO type I de-icing fluid in pre-mix 50/50 and an ISO type II de-icing fluid for icing

protection from the company Clariant are being used. The fluids Safewing MP I „1938 ECO“ and MP II

„FLIGHT“ that we use have all required specifications for a high quality de-icing or icing protection. The

various holding times and mixing ratios are provided in the tables (see attachment H to J).

The de-icing fluid MP I 1938 ECO is used for de-icing in a pre-mixed ratio of 50/50 for all aircraft, and

the de-icing fluid MP II FLIGHT is used in the two Step procedure for icing protection. This use is

regulated by the hold over timetables (attachment H to attachment J).

Important Note: When using the icing protection fluid Safewing MPII FLIGHT (ISO type II FLUID), the BRANDNAME SPECIFIC HOT-TABLE is used, which has considerably longer hold over times.

When using the tables, please note that extreme weather conditions such as freezing rain can greatly shorten the

hold over time.

In the German Aviation Manual (AIP) there is a reference to the de-icing pads DP2, DP3, DP4, DP6, DP7, DP8 and

DP9 on the map AD 2 EDDP 2-5.

DP3 is located on TWY M at apron 1-east side and is used if the north runway and correspondingly the de-icing

pads DP2 and/or DP4 are not available for use.

De-icing is executed by individuals working with running aircraft engines and with (normally) two de-icing vehicles

and one security vehicle. Engines must generally run in idle during the de-icing procedure, and propeller aircraft

must bring their propellers to a stationary position.

In cases of strong icing or contamination (e.g. by snow) of the entire aircraft, it may be necessary to shut down all

engines.


2. Availability of De-icing Resources

During the winter season the traffic centre of Leipzig/Halle Airport and the de-icing coordinator on duty

communicate daily concerning the de-icing resources.

Depending on the daily operative flight plan, up to two de-icing pads may be run concurrently with two de-icing

vehicles per pad.

De-icing can be available up to 24 hours around the clock, if necessary (H24).

Briefing

At about 5 p.m. there is a daily coordination conference initiated by the traffic manager on duty (VvD) with the

following participants:

dispatcher aircraft de-icing (FE) Tel.: 0341 224 2180/2181

traffic manager on duty (VvD) Tel.: 0341 224 1130

This conference addresses:

Agreements concerning weather, flight plan peaks, etc.

Time-scheduled availability of de-icing resources (Personnel, vehicles, number of pads operating) provided by

dispatcher FE

The results of this conference are communicated to the tower immediately by the VvD.

De-icing Pads

De-icing for all airlines, except airlines processed on apron 4, normally occurs on de-icing pads DP2, DP3, DP4,

DP6, DP7, DP8 or DP9 as a requirement of the environmental agencies. The decision to use a DP is based upon

which RWY is active (compare procedure for requesting de-icing).

3. Order of De-icing and Requesting De-icing (see Attachment A - Priorities)

The tower LEJ establishes the order of de-icing generally based on the „first come - first served“ principle.

To satisfy operative needs of customers, however, a priority catalogue has been established with the participating

parties (AOC) which determines a modified order as needed (traffic peaks). (compare attachment A – priorities)

Realizing the order of de-icing requires all parties to deliberately and responsibly comply with the procedures

agreed upon and to immediately pass on any information that would result in a change of the de-icing order (e.g.

technical problems, delays in handling, etc). To keep delays to a minimum, boarding / loading should commence

as soon as possible.

The traffic centre determines the order of de-icing according to the current flight plan (ETD) and the priority

catalogue.

Internal airline priorities should be agreed upon with the dispatcher FE and the traffic centre at least 30 minutes

prior to ETD.

If radio discussions concerning priority take place, the traffic centre should always be consulted.


Ambulance and government flights always have a higher priority in the order of de-icing, even if the request

comes at the last moment or if there is a time delay.

According to the German Aviation Manual (AIP) page AD 2 EDDP 1-12:

A request for de-icing must be communicated in a timely manner (60 minutes before the EOBT) to the traffic

centre of the airport; however, this must be done 15 minutes prior to STD at the latest.

The order of incoming requests does not influence the actual de-icing sequence. This is determined exclusively by

the traffic centre of the airport.

The criterion of the order of de-icing are the EOBT-times. If there are start-SLOTs (CTOT), this is considered

accordingly in the de-icing sequence. The same is valid for changes in the EOBT/CTOT-time.

The parties involved have created a catalogue determining the order of de-icing.

De-icing is requested at the traffic centre (Tel. 0341/224-1130)

The traffic centre passes this information and the order of de-icing on to:

a) the de-icing dispatcher of PG-LEJ and

b) the tower LEJ.

Note:

The traffic centre enters an “R” in the column „De-icing“ when a de-icing request is made at the AMS.

PortGround GmbH confirms this via the data transfer system, where the “R” is then changed to an “S”. The

confirmation of this request occurs by entering a „2“, „3“, „4“, „6“,“7“,“8“ or „9“, indicating which de-icing

pad will be used.

This occurs under consideration of the direction of take off, which is determined by DFS, as well as under

consideration of the availability of de-icing pads, which PortGround reports to the traffic centre at the beginning

of a shift.

The end of a de-icing procedure is indicated in the AMS by an “E”. If a requested de-icing is no longer needed,

this is indicated by an “X”.

A requested de-icing which is no longer needed or should no longer be conducted must be cancelled as quickly as

possible (resource planning), but at the latest 15 minutes before STD. If this does not happen, an invoice will be

generated billing a de-icing procedure using no de-icing fluid.


4. Engine Start / Taxiing to the De-icing Pad

The aircraft taxis to the de-icing pad under its own power, but the engines of propeller aircraft without propeller

brakes must be turned off for de-icing (compare point 1).

The engine start time is very important. The tower LEJ aims to keep the engines from running too long while

aircraft are waiting at the de-icing pad.

However, if aircraft desire to be towed to the de-icing pad (e.g. for pre-de-icing), this is a service towing that will

be invoiced according to the price schedule of FLHG/PG-LEJ.

a) Towing with a Tow Bar

The handling agent accompanies the aircraft (radio contact) from taxiing away from the park position to

starting the engines and leaves after de-icing is successfully completed.

b) Towing without a Tow Bar

Service towing (also for push-back) unaccompanied by the handling agent occurs under the condition that

German-speaking crews are present who know that during this time period directives in German will be

used. The handling agent provides the headsets needed.

5. OFF – Block – Time

The tower LEJ provides the OFF-Block-time for the AMS when taxiing away from the park position.

6. Taxiing to the de-icing pads DP2, DP3, DP4, DP6, DP7, DP8 or DP9

Taxiing to de-icing pad DP2, designed for RWY 08L, occurs via TWY W1 and TWY C. Taxiing to runway 08L

occurs alternatively via TWY G1-B and A2, in case the complete runway length is needed, or via TWY C and TWY

A3 (inasmuch as snow conditions permit).

Taxiing to de-icing pad DP3 occurs via the circle TWY N - position 141 - DP3 - TWY M - TWY N. The wingspan is

limited to 52 meters. The use of DP3 requires that taxiing as described is possible (please consider the usage level

of the apron). In addition, the water station must be advised via the dispatcher for aircraft de-icing – this concerns

debris removal. Notification occurs at the following numbers:

Mr. Rühling Tel. 1469 or

Mr. Kostka Tel. 1277 or

Mr. Heinrich Tel. 1560

If they cannot be reached, or on weekends, advise the group LEJ-T/A (technical readiness service) through the

traffic centre.


Taxiing to de-icing pad DP4, designed for RWY 26R, occurs via TWY E8 and TWY C; taxiing to runway 26R via

TWY C and A8/A9.

Taxiing to de-icing pad DP6, designed for RWY 08R, occurs via TWY S1 or TWY Y and TWY V. For taxiing to DP6

use the yellow guiding line (ground light green).

Here the wingspan is limited to 52 meters (e.g. up to an MD11). This procedure may also be used when the

maintenance area is occupied. One must pay attention that the ground light of the guiding line ORANGE

(green/orange oscillating) is not turned on! If necessary, inform the tower LEJ to have the ground light orange

turned off (see attachment E).

For aircraft with a wingspan of more than 52 meters (e.g. B777, B747, AN124):

If the maintenance area is occupied, DP6 may not be used.

If the maintenance area is available, it can be used for LFZ of the category E and F (up to A380). Taxi over the

zig-zag guiding line ORANGE (ground light green/orange oscillating). The ground light of the guiding line

ORANGE must be additionally switched on by the TOWER!

Taxiing to de-icing pad DP7, designed for RWY 08R, occurs via TWY T, TWY S3 and TWY V.

Taxiing to de-icing pad DP8, designed for 08R and also for RWY 26L, occurs via TWY V. De-icing on DP8 presents

no hindrance if a LFZ from taxi lanes Z2.1 and Z2.2 wants to taxi west or a LFZ from taxi lanes Z3.1 and Z3.2

wants to taxi east via TWY V (see also attachment D).

Taxiing to de-icing pad DP9, designed for RWY 26L, occurs via TWY V. De-icing on DP9 presents no hindrance if a

LFZ from taxi lanes Z4.1 to Z4.3 wants to taxi via TWY S8 (also see attachment D).

On all de-icing pads careful attention must be paid to traffic taxiing through!!!

7. Availability, Beginning Work at Stations and Executing De-icing

7.1 Availability of De-icing Stations

During the winter flight plan, aircraft de-icing is available 24 hours a day.

Here de-icing normally occurs during main traffic times on two de-icing pads (DP2 for RWY 08L and DP4 for RWY

26R, DP6 and DP7 for RWY 08R and DP8 and DP9 for RWY 26L; if needed (driveway maintenance, etc.) DP 3 can

also be used.

7.2 Beginning Work at De-icing Stations

De-icing crews take position at the de-icing pads without previously registering their presence on the pads with

the tower LEJ/DFS. Registering with the tower LEJ to drive onto any de-icing pads is absolutely required during

CAT II/III conditions, or whenever the CAT III warning sign is illuminated and the yellow light on top is blinking.


After taking position on the de-icing pad, the entire de-icing pad area becomes the responsibility of the personnel

working there; there is no need for any further radio contact for entering or driving on the de-icing pad. Each

person is responsible for watching for traffic taxiing through.

There are no traffic announcements from the tower LEJ concerning traffic taxiing through.

Before driving onto the de-icing pads DP 08 and DP 09, the de-icing crew must always sign on with the security

station (by telephone HA 1474) and sign off when leaving the pad.

The area of each de-icing station or the driveway to it (except for DP3) is designated on the south side by a red

safety line. A further red safety line is on the north side of the de-icing pads. This results in areas for various usage

on the north and south side of the de-icing pads. These areas have the necessary room on the sides to allow

taxiing through of aircraft up to 52.00 meters wingspan.

The de-icing crew may approach the aircraft with their vehicles only after establishing contact with the aircraft

over the frequency determined for the respective de-icing pad on the VHF-de-icing frequency (see attachment G

for frequency schedule).

In all other cases, the de-icing crew must provide the necessary clearance for the respective wingspan category:

Up to category D, wingspan up to 52.00 meters, clear the area between the red lines.

Wingspan over 52.00 meters (categories E and F): clear the area completely up to the built up edges of the

area or station.

The de-icing crew has been instructed concerning entering and driving on de-icing pads.

7.3 Executing De-icing

The actual de-icing is regulated by internal procedures valid for all personnel directly involved with de-icing.

For communication between aircraft crew and de-icing groups, regulated aircraft radio frequencies are available

for each de-icing pad (see attachment G). German air traffic control (DFS) advises when to switch to which VHF

frequency before taxiing onto the de-icing pad.

Before beginning de-icing, it must be determined if the aircraft will have an operating runway to use after de-

icing. Communication with winter snow service and the traffic center can help here to avoid having to perform

multiple de-icings.

After completing de-icing, the coordinator advises the aircraft crew to change frequency back to the frequency

“Leipzig ground”.

8. Taxi Clearance by the Tower LEJ


The hold over time of de-icing fluid is limited. When taxi clearance is given, the aircraft should take off as soon as

possible.

The responsibility for determining if the hold over time suffices for taking off lies solely with the pilot in command

of the aircraft.

9. Special De-icing Cases

The ramp agent of each handling company must be asked to inform whether the pilot in command requests a

special de-icing as described in points 9.3 (de-icing of engine intakes, rotor blades, landing gear and radoms) and

9.4 (cockpit window). The appropriate aircraft mechanic/technician must be advised timely (at least 30 minutes

before OFF BLOCK). Special equipment (hot air equipment, ladder, etc.) and/or special de-icing must also be

ordered at least 30 minutes before OFF BLOCK with PortGround.

9.1 Pre-De-icing

Leipzig/Halle Airport permits pre-deicing and anti-icing, which is conducted before take-off with engines running,

to be invoiced not separately but as one event. The amount of de-icing fluid used is billed as the total amount

used.

During pre-de-icing care must be taken to keep the amount of contamination at the entry doors and at recesses

low to avoid complaints from crews and passengers.

Trained aircraft personnel or an aircraft mechanic must be present during the procedure.

Since pre-de-icing occurs only seldom, there is an urgent need for all those involved in the process on the apron

(handling agent, traffic supervisor, PG-LEJ, aircraft technician, crew) to look at the aircraft and subjectively

estimate whether the de-icing procedure will take a longer amount of time and then to pass this information on.

Only such a notice can influence the order of de-icing.

PortGround – de-icing checks whether it is logistically feasible and meaningful to conduct such de-icing

procedures on the de-icing pad for the opposite take-off direction.

9.2 Engine Start Assistance

PortGround – de-icing keeps start assistance for propeller aircraft ready close to the de-icing pads. Start assistance

is invoiced according to the de-icing price catalogue.

9.3 De-icing of Engine Intakes, Rotor Blades, Landing Gear and Radoms


De-icing of engine intakes, rotor blades, landing gear and radoms must be ordered timely (at least 30 minutes

prior to STD) from the VZ of the airport or from PortGround „de-icing“.

The responsible party for ordering special de-icing and the equipment needed for it is the handling

agent/technician of the respective airline.

De-icing the engine no. 2 of an MD11 must be done by an aircraft mechanic / technician of the respective airline.

PortGround provides the necessary equipment and help in executing the procedure.

If the capacity should be exhausted based on several concurrent de-icing requests, the principle „first come, first

served“ is used.

9.4 Cockpit Window

The cockpit window should be free of snow and ice before „OFF BLOCK“. De-icing occurs at the park position by

an aircraft mechanic / technician.

9.5 Aircraft with low rotation speeds (small aircraft)

With expected de-icing of small aircraft, the personnel of the General Aviation Terminal (GAT) must request the

rotation speed of the aircraft from the pilot in command.

With a rotation speed < 85 knots, de-icing is only possible with ADF type 1 fluid. If this is not possible, then de-

icing with type 2 fluid may have a maximal mixture of ADF to water of 50:50 (up to maximally -3°C).

The dispatcher advises the de-icing crew concerning this mixture.

9.6 Stopping De-icing

Based on extreme weather conditions, de-icing may no longer be possible or reasonable.

From wind speeds of 20.5 meters/second (corresponds to 39 knots) upwards, de-icing is not allowed.

With very strong precipitation (snow, freezing rain, etc.) there are no hold over times for de-icing fluid.

With temperatures under -29°C it is not longer possible to use de-icing fluid.

9.7 Repeat De-icing

If, contrary to expectations, an already de-iced aircraft should exceed the hold over time (HOT), making a repeat

de-icing necessary, a new de-icing pad is assigned based on consultation between the tower LEJ and the de-icing

dispatcher of PortGround.

10. Note


The procedures presented in points 1 to 9 are the result of consultations between those involved in the

procedures.

During the course of the running procedure, if it should be necessary to change the procedure in some points, all

parties involved are obligated to cooperate and help.
