1.1   CIVIL
1.1.1   Rescue and Fire Fighting Services
1.1.1.1   Public Aerodromes

Belgian public aerodromes (according AD-1.3) are provided with RFFS and means whose essential purpose is to save lives in case of aircraft accident or incident occurring at or in the vicinity of an aerodrome.

The ensured protection level defined by the aerodrome category is published in section AD 2.6 of the aerodrome concerned. The aerodrome category is defined depending on the characteristics of the largest aircraft (aircraft overall length and maximum fuselage width) normally using the aerodrome and by the number of movements of the largest aircraft.

Rescue and fire fighting services are equipped according to the following table:

1.1.2   Snow plan
1.1.2.1   General

The Airport Authority is responsible for maintaining the aerodrome in safe conditions for flight operations and for assessing and reporting associated runway conditions. Seasonal availability and clearing is published in section AD 2.7 of the aerodrome concerned.

Whenever possible, runways will be cleared to expose the pavement. Various different clearing equipment and methods are used on various aerodromes. These methods are published in section AD 2.7 of the aerodrome concerned. Possible clearing equipment: sweepers, blowers, ploughs, stand-sweepers, spreaders, de-icers for taxiway/runway (liquid and solid).

The type of de-icing compounds and their conditions of use are the subject of special instructions given to aerodromes in due time, in keeping with the latest developments in this area.

Priority in clearance will normally be: runway, taxiways to aprons, aircraft stands on major aprons, remaining taxiways and aprons. More detailed cleaning priorities are published in section AD 2.7 of the aerodrome concerned.

1.1.2.2   Surface Friction Assessment on a Runway

There is an operational need for reliable and uniform information concerning the surface condition of contaminated runways. An indication of surface friction characteristics is helpful in conducting runway condition assessment. It can be obtained by a skilled assessor.

The friction conditions of a runway can be assessed in descriptive terms of “estimated surface friction”. The estimated surface friction is categorized as good, medium to good, medium, medium to poor, and poor, and promulgated in SNOWTAM format and ATC phraseologies.

Assessment results of the estimate friction on the surface of runways, affected exclusively by ice/compacted snow, will be made by means of the following table:

Measured coefficient μEstimated surfaceCode
0.40 and aboveGood5
0.39 to 036Medium to good4
0.35 to 0.30Medium3
0.29 to 0.26Medium to poor 2
0.25 and belowPoor1

If the surface is affected by snow or ice and the estimated surface friction is reported as “good”, pilots should not expect to find conditions as good as on a clean dry runway. The value “good” is a comparative value and is intended to mean that aeroplanes should not experience directional control or braking difficulties, especially when landing. The figures in the “Measured Coefficient μ” column are given as an indication.

1.1.2.3   Dissemination of Conditions

The airport authority is responsible for reporting changes in the state of movement areas to the ATS unit. A SNOWTAM according (EU) 2017/373 Annex VI Part-AIS, ATC phraseologies according (EU) 923/2012 (SERA) and ATIS according (EU) 923/2012 (SERA) Section 9 Flight Information Service is used.

The designated authority to co-ordinate information about the current state of progress of snow clearance operations and the conditions of the movement area is published in section AD 2.7 of the aerodrome concerned.

1.2.2.1   Maintenance of Aerodrome Movement Areas in Conditions of Frost and Snow

The airport authority is responsible for maintaining the aerodrome in satisfactory security conditions for flight operations and for assessing and reporting associated runway conditions.

Whenever possible, the movement area will be kept clear of snow, ice, slush and standing water. The Belgian Air Component will give priority to keep clear the runway and QRA taxiways at EBBL and EBFS.

The maintenance of the movement area will be assured by means of brushes, snowploughs, snowblowers and chemicals.

1.2.2.2   Reporting of Braking Action

If SNOWTAM must give information on the braking action, the three equal sections of a runway will be referred to as A, B and C.

Section A will always be the first third measured from that end of the runway with the lowest runway designation number.

However, in landing instructions, the three sections will be referred to as the “first”, “second” or “third” part of a runway seen from the threshold.

1.2.2.3   Friction Coefficient

The friction coefficient is given by a special tool and data are available after the runway inspection. If no friction tool is available, the friction coefficient is estimated by the local ATC authorities.

Information on braking action will be given according to the following table:

Measured friction coefficientEstimated braking actionCode
0.40 and aboveGood5
0.39 - 0.36Good to medium4
0.35 - 0.30Medium3
0.29 - 0.26Medium to poor2
0.25 or belowPoor1
9 - unreliableUnreliable9

Note: “Unreliable” will be reported when more than 10 % of a runway surface is covered by wet ice, wet snow and/or slush. Measuring results and estimates are considered absolutely unrealistic in such situations. In reports “unreliable” will be followed by either the friction number given by the instrument used or the estimated braking action.
