FRICTlON MEASURING DEVICES USED AND FRICTION LEVEL BELOW WHICH THE RUNWAY IS DECLARED SLIPPERY WHEN IT IS WET.

5.1

Responsibility

5.1.1

The Airport & Aviation Services (S.L)(Private) Ltd is responsible for maintaining the civil aerodromes in a satisfactory condition for flight operations.

5.2

Measuring of Runway Surface Friction.

5.2.1

The friction of the runway is measured periodically by use of a Mu-Meter Trailer. This friction tester equipped with self-wetting features and friction measurements are taken on the runway surface at a speed of 65km/h with 1mm thick water depth underneath of testing wheels. The equipment consist of small threewheeled trailer incorporating electronic measuring systems which operate in conjunction with a computer carried in the chosen towing vehicle. The trailer systems produce signals which are presented on the laptop screen and provide continuous register of the mean coefficient of friction values.

5.2.2

Friction tests will be made over the usable length of the runway,by sections of one third of the length,and at approximately to 7M each side of the centreline in such manner as to produce mean value for the runway.

5.2.3

Should the friction value fall to 0.42 or less,NOTAM will be promulgated to notify the runway as liable to be slippery when wet.

5.2.4

The following table would be adopted by civil Engineering (maintenance) Division of the Airport & Aviation Services (S.L) Ltd when they report the friction values tested on the runway.

Friction value(from Mu-Meter Trailer)	Airport & Aviation Services (S.L)(Private) Ltd's comment on values obtained
>0.42	Normal
<0.42	May be slippery when wet (NOTAM would be issued)

AIRCRAFT ACCIDENT / INCIDENT REPORTING PROCEDURE

In order to speed up the process of investigation of the various categories of aircraft accident / incident occurring at all aerodromes listed under sub section AD 2, all aircraft operators as a mandatory requirement shall follow the procedure detailed in the Sri Lanka AIC Nr. A01/20 dated 20th July 2020 and use the standard Aircraft Accident/Serious incident Reporting Form (CAA/AU/003) which is available as an attachment to the AIC to report such occurrence.

6.2

The Aircraft Accident/Serious incident Reporting form (CAA/AU/003) is available at all ATS/AIS Units. It can also be downloaded from the CAASL web site www.caa.lk.

RUNWAY SURFACE CONDITION ASSESSMENT AND REPORTINGRUNWAYSURFACE CONDITION ASSESSMENT AND REPORTING

7.1

Introduction of GRF

The new ICAO methodology for assessing and reporting runway surface conditions, commonly known as the Global Reporting Format (GRF), enables the harmonized assessment and reporting of runway surface conditions and a correspondingly improved flight crew assessment of take-off and landing performance.

The GRF includes an agreed set of criteria used in a consistent manner for runway surface condition assessment, unique runway condition code (RWYCC) linking the agreed set of criteria with the aircraft landing and takeoff performance, braking action experienced and eventually reported by flight crews; coverage, contaminant type and depth, and a standardized common terminology and phraseology for the description of runway surface conditions that can be used by aerodrome operator inspection personnel, air traffic controllers, aeronautical information services officers, aircraft operators and flight crew.

7.2

Responsibility

7.2.1

Air Traffic Services

i. Being familiar with the contents of the last issued Runway Condition Report (RCR), continuously monitoring the changes in the vicinity that could affect the runway surface contamination and the surface conditions to determine whether a runway inspection is required to be carried out to assess the runway surface condition.

ii. Summon the responsible officer of the aerodrome operator to conduct a Runway Inspection and facilitate him to complete the assessment.

iii. Checking the received RCR to ensure the accuracy, relevancy, and timeliness of the contents of the report to the best of the knowledge and experience, to determine whether any significant change in the runway surface condition has been reported in order to disseminate via Automatic Terminal Information Service (ATIS) broadcast and/or Air-Ground Voice Communication and/or promulgating a SNOWTAM.

iv. Transmitting the information contained in the RCR to the approaching aircraft without delay, updating the ATIS Broadcast and forwarding the SNOWTAM Request form to AIS Unit/AASL for dissemination as appropriate.

v. Coordinating with the MET office during night operations or at any other adverse weather conditions to get the most updated weather information and forecast to determine the need to conduct an assessment and upgrading/ downgrading process accordingly.

7.2.2

Aerodrome Operator

Assessing the condition of the runway for each third of the runway and issuing a RCR

7.2.3

Aeronautical Information Services

Providing the information received by the ATS on SNOWTAM request form to end users via SNOWTAM.

7.2.4

Aircraft Operators

i. Utilizing the RCR information in conjunction with the performance data provided by the aircraft manufacturer to determine if landing or take-off operations can be conducted safely.

ii. Notifying the Air Traffic Services (ATS), whenever the runway braking action encountered during the landing roll is not as good as that reported by the Control Tower in the RCR, by means of a special air-report (AIREP) as early as possible.

7.3
