International Civil Aviation Organization (ICAO) Regional Aviation Safety Group (RASG) (Asia & Pacific Region) International Civil Aviation Organization (ICAO) Regional Aviation Safety Group (RASG) (Asia & Pacific Region) Asia Pacific Regional Aviation Safety Team (APRAST) INDUSTRY BEST PRACTICES MANUAL FOR TIMELY AND ACCURATE REPORTING OF RUNWAY SURFACE CONDITIONS BY ATS/AIS TO FLIGHT CREW Developed by Airports Authority of India [Name of sub-group and/or Champion and/or Facilitator(s)] Draft Version 4.0 dated 12th June 2013 Executive Summary A great degree of diversity prevails among the ATS/AIS authorities in the methods for assessing a runway surface condition and friction during dry/wet/contaminated states and the procedures/formats for its reporting to the flight crew. So far many studies have been conducted on Runway Friction by various agencies and these have been inconclusive, & presented divergent views. ICAO Friction Task Force (ITF) is working on “Assessment and Reporting of Runway Surface Conditions” and it is expected that a global format for reporting runway surface conditions will be one of the elements of the ITF report. Asia Pacific Regional Aviation Safety Team (APRAST), during its first meeting (APRAST/1) identified Runway Excursion (RE) as a major Runway Safety Enhancement Initiative (SEI) and requested Airports Authority of India to develop “Industry Best Practices Manual on Runway Surface Conditions Reporting by ATS/AIS to Flight Crew” which contains guidelines for assessing and reporting runway surface conditions primarily based on the ICAO documents and with reference to the findings and observations made by various research organizations. Specifically the procedures for timely and accurate reporting of Runway Condition (RCR) by ATS/AIS to flight crew are contained in Chapter 6 of the Manual. BACKGROUND ON REGIONAL AVIATION SAFETY GROUP – ASIA & PACIFIC (RASG – APAC) The Regional Aviation Safety Group Asia-Pacific (RASG-APAC) was established in 2011 by the Council of ICAO. The RASG-APAC is tasked with improving aviation safety in the Asia & Pacific regions by developing and implementing a work programme, in line with the ICAO Global Aviation Safety Plan, aimed at identifying and implementing safety initiatives to address known safety hazards and deficiencies in the region. The Asia Pacific Regional Aviation Safety Team (APRAST), a sub-group of the RASG- APAC, assists the RASG-APAC in its work by recommending safety interventions which will reduce aviation safety risks. The full commitment and active participation of APAC States/Administrations and the industry partners is fundamental to the success of the RASG-APAC in reducing aviation safety risks and accident rates in the Asia and Pacific regions.

Appendix Q TALPA ARC 138 Appendix R UK CAA – UK Winter Runway Assessment Trial 151 2012/2013 TRIAL PLAN& Runway condition reporting format used by Geneva Airport Foreword A great degree of diversity prevails among the ATS/AIS authorities in the methods for assessing a runway surface condition and friction during dry/wet/contaminated states and the procedures/formats for its reporting to the flight crew. For example, a few States prefer to promulgate such information in ATIS broadcast, whereas many other States simply issue NOTAMs. A few other States publish SNOW PLAN in their AIP whereas some other states prefer to issue SNOWTAM as and when conditions necessitate. So far many studies have been conducted on Runway Friction by various agencies and these have been INCONCLUSIVE, & presented DIVERGENT views. In the first meeting of the Asia Pacific Regional Aviation Safety Team (APRAST/1) held during 20-24th February 2012, at ICAO APAC Office Bangkok, the Airports Authority of India was requested to develop a Detailed Implementation Plan (DIP) for preparing a standardized format for reporting of runway surface conditions which may be acceptable to all the stakeholders. To understand the industry best practices in APAC Region a Survey was undertaken vide ICAO APAC Office Bangkok State Letter ref.: T 11/21.1 – AP 081/12 (AGA) dated 14 June 2012. The Regional Aviation Safety Group (RASG) in its meeting held in Delhi during October 2012, approved the DIP on RE 6 as a Priority Safety Enhancement Initiative and also recommended that States respond to the Survey. The ICAO/COSCAPSEA organized a workshop on "State functions and responsibilities regarding the Assessment, Measurement, and Reporting of Runway Surface conditions” from 19th November 2012 to 22nd November 2012 at Bangkok. The fruitful discussions held between the ICAO Friction Task Force Rapporteur and representatives of AAI, helped in gaining deeper understanding of the issues involved in Runway Condition Reporting. AAI thankfully acknowledges guidance provided by an expert from Boeing company in understanding the aircraft manufacturers point of view. The valuable feedback on the presentations received during APRAST Facilitators / Champions Meeting Bangkok, March 13, 2013, has also been used to develop this Industry Best Practices (IBP) Manual. This Industry Best Practices (IBP) Manual is primarily based on the on ICAO Cir 329/AN/191, Assessment, Measurement and Reporting of Runway Surface Conditions. While preparing the IBP Manual examples of NOTAMS/AIP supplement/ AIC on SNOWPLAN, ATMC , relevant guidance material from various sources such as Studies conducted by EASA (European Aviation Safety Agency), TALPA ARC Of USA, FAA, National Aerospace Research Laboratory Netherlands, Accident Investigation Board Norway, International Federation of Airlines Pilot Association (IFALPA), CAA UK, NATS UK, ANNEX-14, ICAO Doc 9137 Airport Services Manual Part 2 – Pavement Surface Conditions have also been added at Appendices part of the draft manual. Airports Authority of India presented a Working Paper on “Timely and Accurate reporting of Runway Conditions by ATS/AIS to Flight Crew” to ICAO Third Meeting of the Asia Pacific Regional Aviation Safety Team (APRAST/3). The Working Paper contained a comparative study of ICAO provisions on runway condition assessment and reporting, important findings by various research organizations/agencies and SIX PROPOSALS on runway condition reporting. AS agreed by APRAST/3 ( refer APRAST/3 Report of the Meeting paragraph 6.4.3 ) the SIX PROPOSALS have been assimilated in Chapter 6 of this Industry Best Practices Manual. Airports Authority of India thankfully acknowledges the permission granted by EASA- RuFAB, Accident Investigation Board Norway, National Aerospace Research Laboratory (NLR) Netherlands to refer to their research work on assessment of runway surface condition and reporting. In regard to the response on Survey, AAI would like to place it on record that a strong support was received from M/s Qatar Airways in collecting NOTAMs and SNOWTAMs pertaining to Runway conditions

  • A Hail Size Distribution Impact Transducer
    A Hail Size Distribution Impact Transducer John E. Lanea, Robert C. Youngquistb, William D. Haskella, and Robert B. Coxa aASRC Aerospace Corporation, P.O. Box 21087, Kennedy Space Center, FL 32815 [email protected] [email protected] [email protected] bNational Aeronautics and Space Administration (NASA), Kennedy Space Center, FL 32899 [email protected] Abstract: An active impact transducer has been designed and tested for the purpose of monitor- ing hail fall in the vicinity of the Space Shuttle launch pads. An important outcome of this design is the opportunity to utilize frequency analysis to discriminate between the audio signal generat- ed from raindrop impacts and that of hailstone impacts. The sound of hail impacting a metal plate is subtly but distinctly different than the sound of rain impacts. This useful characteristic permits application of signal processing algorithms that are inherently more robust than tech- niques relying on amplitude processing alone in the implementation of a hail disdrometer. 1 1. Introduction Impact disdrometers have long been a useful meteorological tool to measure and quantify rainfall drop size distributions, where a drop momentum is converted into a single electrical im- pulse.1,2 The electrical impulse amplitude is converted to an estimate of drop diameter by means of an empirical calibration formula. The calibration may be a one-time procedure involving dropping numerous known-size-calibration drops from a tower of sufficient height to achieve terminal velocity. The test drop sizes must adequately span the size range of interest. Alternative- ly, or as a supplement to the single drop calibration, an in situ method of comparing the sum of accumulated drop impulses to the tip time interval of a tipping-bucket rain gauge may be uti- lized.3 Prior to launch, the Space Shuttle and other NASA launch vehicles are primarily large ther- mos bottles containing substantial quantities of cryogenic fuels.

  • The Contribution of Global Alliances to Airlines' Environmental Performance
    sustainability Article The Contribution of Global Alliances to Airlines’ Environmental Performance Belén Payán-Sánchez , Miguel Pérez-Valls * and José Antonio Plaza-Úbeda Economics and Business Department, University of Almería, Ctra. Sacramento s/n, La Cañada de San Urbano, 04120 Almería, Spain * Correspondence: [email protected] Received: 27 June 2019; Accepted: 22 August 2019; Published: 24 August 2019 Abstract: Global alliances have traditionally been related to improvements in the economic and operational performances of companies, particularly in the airline industry. However, we still do not know the effect of the participation in this kind of multilateral agreement on the environmental performance of airlines. The main aim of this work is to analyze whether the alliance membership of airlines has an effect upon their environmental performance, and if so, whether or not the characteristics of the global alliance, as well as the business model of the airline, may influence this relation to a greater or lesser extent. The results of regression and Analysis of Variance (ANOVA) in a sample of 252 airlines (58 included in one of the three global alliances: Star Alliance, Oneworld, and SkyTeam) show a strong and inverse relationship between environmental performance and belonging to an alliance. The paper also shows empirical evidence of the influence of the business model of the airline on environmental performance. These results suggest important implications for managers facing challenges regarding sustainability. Keywords: global alliances; sustainability; environmental performance; airlines; aviation 1. Introduction The aviation sector is the fastest-growing source of greenhouse gas emissions worldwide [1]. Many authors and corporations, such as the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA), agree that environmental sustainability may be achieved through external pressure with the imposition and accomplishment of different policies, regulations, taxations and other fiscal instruments [2–6].

It studies alliances and mergers implications on air transport, and suggests the development of frameworks for their regulation. Action: The Conference is invited to agree to the recommendations presented in paragraph 6. References: ATConf/6 reference material is available at www.icao.int/meetings/atconf6. 1. INTRODUCTION 1.1 Significant developments have occurred in the field of air transport. A large number of countries made remarkable progress in liberalizing international air transport regulations, and became involved in full market-access arrangements. At the same time, the airline industry underwent a major shift and saw the forging alliances and mergers between companies in order to consolidate their presence in a market environment characterized by strong competition. 1.2 Alliances between airlines have become a dominant feature in air transport, and a new global phenomenon unfolding relatively quickly through multiple collaborative business arrangements. Alliance agreements took different forms and included various elements of code-sharing, marketing and pricing cooperation, schedules coordination, and offices and airport facilities sharing.

  • The Braking Force
    association adilca www.adilca.com THE BRAKING FORCE From the point of view of driving, emergency braking is probably the most difficult skill to perform. Yet it is an essential skill because, according to the Highway Code, only braking allows the driver to remain in control of one’s car. What does physics teach us about braking? What should be measured? What can be calculated? What about the braking force, this particular force without which nothing would be possible? What do we know about it? Here are some answers. Braking tests If you want to explore the secrets of braking, tests involving a driver, a modern car and a test track are necessary. The few measures will then be used for various calculations. This kind of test is regularly organized by automotive testers, and the obtained results have much to teach us. But to guarantee reliable measures, how is it necessary to proceed? And what do we have to measure? Choose the right track! At first, what track to choose? It must obey the some characteristics: a flat road, a long straight line without slope or banking, stocked with uniform cover, an asphalt of last generation if you wish to measure maximal performance of braking. The car must be recent, in good mechanical condition and entrusted to a driver able to brake efficiently (not so frequent it seems!). A passenger is required to balance the masses. Let’s go! A classic method: the decametre! The more traditional method is to measure the initial speed of the car and the braking distance.
