REPORT OF THE NINETEENTH MEETING OF THE CO-ORDINATION GROUP FOR METEOROLOGICAL SATELLITES CGMS XIX TASHKENT, USSR 10 - 14 DECEMBER 1990 REPORT OF THE NINETEENTH MEETING OF THE CO-ORDINATION GROUP FOR METEOROLOGICAL SATELLITES CGMS XIX TASHKENT, USSR 10 - 14 DECEMBER 1990 A. PRELIMINARIES A.1 Introduction CGMS-XIX was convened at 10.30 am on 10 December by Mr. V. Kharitonov, Deputy Director of the satellite division, Hydromet Centre of the USSR, Moscow. In his welcome address, Mr N.N. Aksarin, Director of the Uzbekistan Met Service expressed his great pleasure that CGMS had chosen Tashkent as the meeting venue for CGMS XIX. Tashkent, he added, would be one of the main data processing centres for GOMS. The construction of the building was complete and a new computer system was currently being installed. He noted that the meteorological centre in Tashkent was already very aware of the importance of satellite imagery for weather forecasting, especially for observing the weather in neighbouring rather data sparse regions. Satellite data had been received in the centre for some 20 years. He looked forward to a close cooperation with the Members of CGMS over the coming years and wished the delegates a very enjoyable stay in Tashkent and a most productive and successful The reader should note that a full list of acronyms and abbreviations can be found in Annex I. A.2 Election of Chairman Mr D.E. Hinsman, Senior Scientific Officer, Satellite Activities, WMO, was elected Chairman of this session of CGMS. Mr N.F. Veltishchev, Deputy Director of the Hydromet Centre of the USSR, Moscow, was elected Vice Chairman. A.3 Arrangements for the Drafting Committee A Drafting Committee, comprising Messrs. G. Bridge (EUMETSAT) and C. Cripps (USA) was appointed. CGMS Members were requested to nominate a representative to provide inputs to this drafting committee. A.4 Adoption of Agenda and Work Plan of Working Group Sessions The Agenda (see Annex II) was adopted. CGMS agreed the work programme of the Telecommunications and Satellite Products Working Groups. Mr L. Heacock (USA) was elected Chairman of the Telecommunications Working Group and Mr J. Morgan (EUMETSAT) the Chairman of the Satellite Products Working Group. The reader 1 should note that the numbering of chapters in this report correspond to those used in the Agenda. A full list of Working Papers (WP) submitted to CGMS XIX can be found in Annex III. A.5 Review of Actions from Previous Meetings The Secretariat reviewed actions from previous CGMS meetings: i) Continuing Actions by All Parties 1. Circulation of satellite Operating Quarterly Reports Status: Operations reports were being regularly distributed to all CGMS members. 2. Quarterly exchange of Photography Status: Photographs had been exchanged. 3. Intercomparison of Extracted Winds Status: Results of intercomparison carried out by USA in January 1990 had been distributed (July 1990 data provided in CGMSXIX-USA-WP-12). 4.

    U.S. Department Advisory of Transportation Federal Aviation Administration Circular Subject: Oceanic and International Date: 8/12/10 AC No: 91-70A Operations Initiated by: AFS-400 Change: FOREWORD This advisory circular (AC) contains general information and guidance for operators planning oceanic flights, including authorizations needed for operations outside the continental United States. This includes Special Areas of Operation (SAO) such as North Atlantic Minimum Navigation Performance Specifications (NAT/MNPS), Reduced Vertical Separation Minimum (RVSM), Area Navigation (RNAV), and Required Navigation Performance (RNP) airspace. The dynamics of oceanic operations are such that they are constantly evolving and it is incumbent on the operators to closely monitor any changes. The Federal Aviation Administration (FAA) revised this AC to point the reader to the most current sources of international material. In many cases, the references are to a Web site. The material, however, is still found at www.faa.gov or calling a Federal Aviation Administration (FAA) navigation specialist. This AC includes specific guidance for authorizations and other FAA policy issues. A detailed study of the FAA Web site is the best source for introduction information about oceanic, international, and remote operations. John M.

This guide is designed in three layers to accommodate users who require different levels of understanding. Layer 1 is a general description designed for those who need to become familiar with the table driven code forms but do not need a detailed understanding. Layer 2 focuses on the functionality and application of BUFR and CREX, and is intended for those who must use software that encodes and/or decodes BUFR or CREX, but will not actually write the software. Layer 3 is intended for those who must actually write BUFR or CREX encoding and/or decoding software, although those wishing to study table driven codes in depth, will find it equally useful. The WMO gratefully acknowledges the contributions of the experts who developed this guidance material. The Guide was prepared by Dr. Clifford H. Dey of the U. S. A. National Centre for Environmental Prediction. Contributions were also received in particular from Charles Sanders - Australia, Eva Cervena - Czech Republic, Chris Long - U.K., Jeff Ator - USA and Milan Dragosavac, ECMWF.

  • Planning for Delay: Influence of Flight Scheduling on Airline Punctuality

    Planning for Delay: Influence of Flight Scheduling on Airline Punctuality

    Planning for Delay: influence of flight scheduling on airline punctuality EUROCONTROL Trends in Air Traffic Volume 7 EUROCONTROL Acknowledgements The idea for this study came from the Performance Review Commission reporting on the performance of European Air Navigation Services (ANS) in 2008 in the Performance Review Report (PRR20081). The PRR2008 reports on Key Performance Areas of Safety, Punctuality and Predictability, Capacity/delays, Flight-Efficiency, Cost- Effectiveness and Environmental impact. Within the area of punctuality and predictability, a comparison between the USA and Europe showed similar arrival punctuality rates albeit with higher variability in the US. In section 7.4.4 of PRR2008 we read that “The gap between departure and arrival punctuality is significant in the US and quasi nil in Europe”. This document has been developed to help explain why this gap is so small in Europe and how airlines themselves can influence it. Bo Redeborn, EUROCONTROL Director Cooperative Network Design, approved the further development of this series of studies with the objective of increasing the depth of knowledge. I am grateful to him for his support and encouragement. Thanks go to the STATFOR team, Claire Leleu and Magda Gregorova for their technical support and expertise. I am grateful to EUROCONTROL’s Corporate Communications Service, Caroline Cochaux and Lucia Pasquini for their help in the design and publication of this document. Thanks go to a number of people who gave their input, reviewed the document, suggested changes and helped in the proof reading. Notable amongst these were Milena Studic during her traineeship at CODA, Eric Moyson from IACA, Mark Deacon from Monarch Airlines, Daniella Massart from Brussels Airlines, Gerrit Klempert and Jens Armenat from Lufthansa.

Table D is a device to reduce these overheads; (c) Each entry within Table D contains a list of descriptors. Each sequence descriptor that references to Table D may be “expanded” by replacing it with the list corresponding to that entry. The process of “expansion” is well defined, provided it results in a set of element descriptors and operator descriptors; (d) Descriptors listed in entries to Table D may themselves refer to Table D, provided no circularity results on repeated expansion; (e) The initial Table D has been limited to lists of descriptors likely to be used frequently.
