Page 2 AC 175.01 UNCONTROLLED DOCUMENT WHEN DOWNLOADED Version 2.0 Consult the GACA website for current version GACA الجماعه العامه للطيران المحدني General Authority of Civil Aviation Chapter 2 - NOTAM 2.1 General The provision of accurate and timely information concerning the availability of aeronautical facilities is a key feature of an effective air traffic management system. The use of NOTAM in the distribution of such information is an important tool in securing the safe and efficient operation of flights. GACAR Part 175.137 identifies the requirements for the provision of such information using NOTAM. This chapter provides further guidance on the issue and content of NOTAM. 2.2 Issuing NOTAM NOTAM are issued to inform airspace and aerodrome users of important information concerning the availability of aeronautical facilities procedures or services, or of hazards to flight. Examples of issues that may generate the need to take NOTAM action include: (a) Hazards to airspace users; (b) The closure of operational facilities such as runways, taxiways, etc.; (c) Unserviceable communications systems or navigational aids; (d) Unusual airspace activities resulting in airspace restrictions; (e) Unserviceable lighting; (f) The presence of temporary obstructions near an aerodrome. The full list of information that require the issue of a NOTAM can be found in GACAR Part 175.137. For reasons of conciseness and precision, NOTAM are encoded using agreed international terms, although the code is usually sufficiently self-evident to allow the user to identify a hazard. 2.3 Distribution of NOTAM NOTAM must be communicated by certified aeronautical information service providers using the fastest available means to all addressees for whom the information is assessed as being of direct operational significance, and who would not otherwise have at least seven days' prior notification. Trigger NOTAM serve to alert those who maintain aeronautical databases that specific changes will be effective soon, usually at the next AIRAC date. A trigger NOTAM contains a brief description of the contents of the amendment or supplement, the effective date and the reference number of the amendment or supplement. It is usually valid for 14 days. NOTAM are originated and issued for Jeddah FIR and are distributed in series identified by letters as described in KSA AIP GEN 3.1. The risk to flight that is posed by ash associated with volcanic eruptions is notified as a special message known as an ASHTAM. Page 3 AC 175.01 UNCONTROLLED DOCUMENT WHEN DOWNLOADED Version 2.0 Consult the GACA website for current version GACA العربيه الحامه للطيران المدني General Authority of Civil Aviation A special series NOTAM, named SNOWTAM, is used to notify the presence or removal of hazardous conditions on the movement area due to snow, slush, ice, frost, standing water, or water associated with these conditions on the movement area. Full details concerning the content and distribution of NOTAM, ASHTAM, and SNOWTAM are contained in GACAR Part 175. Page 4 AC 175.01 UNCONTROLLED DOCUMENT WHEN DOWNLOADED Version 2.0 Consult the GACA website for current version GACA الجماعه العامه للطيران المحدني General Authority of Civil Aviation Chapter 3 - The Management of Change 3.1 General All organizations experience changes due to expansion, contraction, improvement to existing systems, the introduction of new products and services, or the introduction of new equipment or procedures. Hazards may inadvertently be introduced into an operation whenever change occurs. Safety management practices require that hazards arising from change are systematically and proactively identified and appropriate measures to manage the safety risks are identified, implemented and subsequently evaluated. The significance of this key activity is highlighted in GACAR Part 5 which requires services providers to develop and maintain processes to identify changes which may affect the safety of its products or services. GACAR Part175.19 is concerned with ensuring that service providers carefully consider the impact that changes to functional systems may have on the safe provision of services. 3.2 The role of change management As systems evolve, sometimes small, incremental changes in the system or in the system's environment can accumulate over time. When changes to systems are made, and periodically thereafter, an organization should review the system, including its operating environment to make sure it continues to meet all its safety performance requirements. It is important that such reviews consider the complete life cycle of the system under consideration; all its components; and the equipment, procedures and human resources that make up the functional system. Reviews should also include the interactions of a system with other systems in use. 3.3 The change management process A formal change management process must identify changes which may affect established processes, procedures, products and services. All necessary measures to maintain safety performance should be identified and described prior to implementing changes. The result of this process is the reduction in the safety risks resulting from changes to as low as reasonably practical. An effective process for change management must consider the following: (a) Criticality of systems and activities: Criticality is closely related to safety risk and relates to the potential consequences of equipment being improperly operated or an activity being incorrectly executed. While this is a consideration that should be made during the system design process, it becomes relevant during a situation of change. Systems that have higher safety criticality should be reviewed following change to make sure that corrective actions can be taken to control potentially emerging safety risks. (b) Stability of systems and operational environments: Changes may be the result of the introduction of new or upgraded systems; changes in the services provided; the award Page 5 AC 175.01 UNCONTROLLED DOCUMENT WHEN DOWNLOADED Version 2.0 Consult the GACA website for current version GACA الجمده العامه للطيران المدني General Authority of Civil Aviation of new commercial contracts; or other changes directly under the control of the organization. Changes in the wider operational environment are also important, such as economic or financial issues, changes in political or regulatory environments, or changes in the physical environment. While these factors are not under the direct control of the organization, it must act to respond to them. (c) Past performance: Past performance of critical systems is a proven indicator of future performance. Trend analyses should be employed to track safety performance measures over time and to factor this information into the planning of future changes. Where deficiencies have been found and corrected because of past audits, evaluations, investigations or reports, it is essential that such information is considered to assure the effectiveness of corrective actions. Page 6 AC 175.01 UNCONTROLLED DOCUMENT WHEN DOWNLOADED Version 2.0 Consult the GACA website for current version GACA الجماعه العامه للطيران المدني General Authority of Civil Aviation Chapter 4 – KSA AIP 4.1 General The promulgation of aeronautical data and aeronautical information is a key requirement for flight safety. All ICAO Contracting States are required to promulgate such data in the form of a standard publication, the Aeronautical Information Publication (AIP). GACAR Part 175.97 identifies the specifications for the publication of the KSA AIP. The KSA AIP is issued in electronic format (html & pdf). The publication of digital data sets in Aeronautical Information Exchange Model (AIXM) format must be as specified in GACAR Part 175.111. 4.2 Publication authority An AIP is issued by or with the authority of the appropriate State and contains aeronautical information and charts of a lasting character essential to air navigation. In the Kingdom of Saudi Arabia, the AIP is published under the authority of the President of GACA. 4.3 Content and structure The content and structure of the KSA AIP document are the subject of international agreement and are specified in Appendix 2 to GACAR Part 175. The KSA AIP contains details of regulations, procedures and other information pertinent to the operation of aircraft in the Kingdom of Saudi Arabia. The KSA AIP is the recognised information source for permanent information and long duration temporary changes relating to aeronautical services in Saudi Arabia. The KSA AIP contains a range of aeronautical information and aeronautical data that requires approval by GACA before publication. Aeronautical information and aeronautical data requiring approval by GACA are identified in GACAR Part 175.49. Full details regarding the content and structure of the KSA AIP are contained in GACAR Part 175 Appendix 2 unless otherwise authorised by the President. Any service provider proposing to include information in a format or to a specification that does not meet the requirements of Appendix 2 to GACAR Part 175 must seek approval of the President prior to publication. 4.4 Updating information Information in the KSA AIP should be kept up to date by regular revision in accordance with the Aeronautical Information and Control (AIRAC) cycle. Revisions should be made in sufficient time to allow users of the aeronautical data to make necessary amendments. Dates of AIRAC amendments to KSA AIP are published by Aeronautical Information Circular (AIC).
