AD 1.2  Rescue and fire fighting services, runway surface condition assessment and reporting and snow plan

1.2.2  SURFACE CONDITION ASSESSMENT AND REPORTING AND SNOW PLAN

1.2.2.1  Subject reporting runway surface condition and winter service

1.2.2.1.1 The aerodrome operator is responsible for assessing and reporting the runway surface condition and winter maintenance of the aerodrome. Priorities for clearing the movement area are listed in the text part of the related aerodrome - LKXX AD.2.7.

1.2.2.2  Movement area monitoring

1.2.2.2.1 The movement area condition is monitored by the aerodrome operator within the published operating hours.

1.2.2.3  Methods for the surface condition assessment for specially treated runways

1.2.2.3.1 Not applicable in the .

1.2.2.4  Measures taken to maintain the usability of the movement area

1.2.2.4.1 The aerodrome operator is responsible for supervising the movement area condition and establishing procedures and conditions to maintain the usability of the movement area. Approximately from November 1st to April 1st, these responsibilities are regulated in the form of an appropriate snow plan.

1.2.2.4.2 Clearance order:

1.  

2.  

3. apron,

4. other RWY, TWY and other parts of movement area and roads, which extend the operational usability and capacity of the aerodrome.

1.2.2.4.3 Snow ploughs, sweeper-blowers and snow cutters are used for removing snow precipitation. In case an ice-accretion is expected treatment of the movement area is carried out by chemical manner to maintain the safe condition of the runway surface.

1.2.2.4.4 Reports will commence once the height of snowbanks adjacent to RWYs reach the values shown in the Figure 1 on page AD 1.2-4.

1.2.2.4.5  The aerodrome operator carries out the coordination with the air traffic control service and meteorological services. A calamity staff is established to provide suitable conditions for air traffic in case of calamity.

1.2.2.5   System and means of reporting

1.2.2.5.1 The assessment is performed in accordance with the procedures governing the Global Reporting Format (GRF) based on the use of the Runway Condition Assessment Matrix (RCAM).

1.2.2.5.2 For the purpose of assessing the condition of the runway surface, each runway is divided into three equal lengths, referred to as the third A, B and C. The third A is the first part of the runway with a lower number. Within landing or take-off instructions, the information is provided for each third of the runway. These are called "first", "second" and "third" seen in the direction of landing or take-off of the aircraft.

1.2.2.6  Cases of runway closure

1.2.2.6.1 In cases where a postponement of cleaning may result in a situation worsening up to a calamity, e.g. when a drop in temperature causes water or slush to turn into solid ice, the airport operator is authorized to demand sections of movement areas to be closed for traffic.

1.2.2.7   Distribution of runway surface condition information

1.2.2.7.1  Information is promulgated by NOTAM/SNOWTAM. SNOWTAM FORM is available on page AD 1.2-6. The instructions for SNOWTAM issuance are on pages AD 1.2-7 to AD 1.2-9.

1.2.2.7.2 SNOWTAMs are disseminated to the addresses listed in the seasonal AIC series A - Seasonal information supplementing snow plan.

1.2.2.7.3  Information on conditions of RWYs at aerodrome PRAHA/RuzyněTAD_HP;Annotation:119077.cze;2826 is also disseminated by MOTNE in the way set down in EUR ANP (DOC 7754).

INSTRUCTIONS FOR THE COMPLETION OF THE SNOWTAM FORMAT

1. General

   1. When reporting on more than one runway, repeat Items B to H (aeroplane performance calculation section).

   2. The letters used to indicate items are only used for reference purpose and should not be included in the messages. The letters, M (mandatory), C (conditional) and O (optional) mark the usage and information and shall be included as explained below.

   3. Metric units shall be used and the unit of measurement not reported.

   4. The maximum validity of SNOWTAM is 8 hours. New SNOWTAM shall be issued whenever a new runway condition report is received.

   5. cancels the previous SNOWTAM.

   6. The abbreviated heading “TTAAiiii CCCC MMYYGGgg (BBB)” is included to facilitate the automatic processing of SNOWTAM messages in computer data banks.

      The explanation of these symbols is:

      TT = data designator for SNOWTAM = SW;

      AA = geographical designator for States, e.g. LK = CZECH REPUBLIC (see Location Indicators (ICAO Doc 7910), Part 2, Index to Nationality Letters for Location Indicators);

      iiii = SNOWTAM serial number in a four-digit group;

      CCCC = four-letter location indicator of the aerodrome to which the SNOWTAM refers (see Location Indicators (ICAO Doc 7910));

      MMYYGGgg = date/time of observation/measurement, whereby:

      MM = month, e.g. January = 01, December = 12

      YY = day of the month

      GGgg = time in hours (GG) and minutes (gg) UTC;

      (BBB) = optional group for correction, in the case of an error, to a SNOWTAM message previously disseminated with the same serial number = COR.

      Note 1: Brackets in (BBB) are used to indicate that this group is optional.

      Note 2: When reporting on more than one runway and individual dates/times of observation/assessment are indicated by repeated Item B, the latest date/time of observation/assessment is inserted in the abbreviated heading (MMYYGGgg).

      Example: Abbreviated heading of SNOWTAM No. 149 from Zurich, measurement/observation of 7 NOV at 0620 UTC:

      SWLS0149 LSZH 11070620

      Note: The information groups are separated by a space, as illustrated above.

   7. The text “SNOWTAM” in the SNOWTAM Format and the SNOWTAM serial number in a four-digit group shall be separated by a space.

      Example: SNOWTAM 0124

   8. For readability purposes for the SNOWTAM message, include a line feed after the SNOWTAM serial number, after Item A, and after the aeroplane performance calculation section.

   9. When reporting on more than one runway, repeat the information in the aeroplane performance calculation section from the date and time of assessment for each runway before the information in the situational awareness section.

   10. Mandatory information is:

       1. Aerodrome location indicator;

       2. Date and time of assessment;

       3. Lower runway designator number;

       4. Runway condition code for each runway third; and
