AOP/WG/4−IP/5 Agenda Item 4 INTERNATIONAL CIVIL AVIATION ORGANIZATION THE FORTH MEETING OF THE AERODROMES OPERATIONS AND PLANNING – WORKING GROUP (AOP/WG/4) Bangkok, Thailand, 23 to 25 May 2016 Agenda Item 4: Provision of AOP in the Asia/Pacific Region ACTIVITIES FOR NEW RUNWAY SURFACE CONDITION ASSESSMENT (Presented by Japan) SUMMARY This paper presents the activities for new runway surface condition assessment. This paper relates to the amendment 13 to Annexes 14, Volume I and the amendment 1 to PANS-Aerodromes. Strategic Objectives: A: Safety – Enhance global civil aviation safety 1. INTRODUCTION 1.1 As stated in ICAO State letter dated April 5, 2016, The ICAO Council adopted at its 207th session in February 2016, the implementation of an enhanced global reporting format for assessing and reporting runway surface conditions. This global reporting format for assessing and reporting surface conditions is based upon the TALPA-ARC approach and is designed to report runway surface conditions in a standardized manner such that flight crew are able to accurately determine aircraft take-off and landing performance, resulting in a global reduction in runway excursion incidents/ accidents. 1.2 The date of application of the global reporting format is November 5, 2020. In preparation for those forthcoming evolutions concerning the assessment and the report of the runway surface, Japan Civil Aviation Bureau established a study group to conduct trial and to examine how to apply to Japan. This paper presents the trial conducted during winter from January to March 2015. 2. ACTION BY THE MEETING 2.1 The meeting is invited to: a) note the information contained in this paper and the attached presentation; and b) discuss any relevant matters as appropriate. ………………………….
