AD 1.2  Rescue and Fire Fighting Services and Snow Plan

1   CIVIL

1.1   Rescue and Fire-fighting Services

Certified aerodromes are provided with RFF services 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 level of protection to be ensured at an aerodrome is determined with respect of;

  • the over-all length and maximum fuselage width of aircraft using the aerodrome.
  • the frequency of their operations on the aerodrome.

The aerodrome category being determined, the ensured protection level is published in section AD 2.6 of the aerodrome concerned.

1.2   Snow plan

The Airport Authority is responsible for maintaining the aerodrome in safe conditions for flight operations and for assessing and reporting associated runway conditions (see AD 2.7).

A minimum allocation of means is applicable to each aerodrome category as stated in ICAO Annex 14 and specified as follows:

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.

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.

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.
