IEC 61820-1-2:2024 describes requirements for AGL systems including power supplies, transformation of energy, cables, and any electrical component utilized to produce the light intended to be used as a visual aid for air and ground navigation based on IEC 61820-1, complemented with series circuit specific topics.

IEC 61820-3-2:2023 specifies the requirements for power electronic converter systems (PECS) dedicated to powering aeronautical ground lighting (AGL) circuits with series circuit topology. An example of a traditional implementation is an AGL circuit with 6,6 A RMS nominal current, powered by a constant current regulator (CCR). In addition to revising the requirements for 6,6 A CCR setups, this document introduces requirements for general PECS for new AGL systems including systems specifically designed for LED based luminaires. This first edition cancels and replaces IEC 61822 published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61822:2009: a) introduction of power electronic converter systems (PECS) to be used in the aeronautical ground lighting systems other than the 6,6 A aeronautical ground lighting systems; b) introduction of classification for different device types; c) introduction of IEC 62477-1:2022 and IEC 62477-2:2018 as the basis for safety related requirements.

IEC 61820-3-4:2023 specifies protective provisions for the operation of lamp systems powered by series circuits in aeronautical ground lighting. The protective provisions described here refer only to secondary supply systems for loads that are electrically separated from the series circuit.

This document also covers the special operational features of aeronautical ground lighting and addresses the level of training and the requirements for maintenance procedures detailed in IEC 61821 and other national or regional regulation. The requirements and tests are intended to set a specification framework for system designers, system installers, users, and maintenance personnel to ensure a safe and economic use of electrical systems in installations for the beaconing of aerodromes. This document complements existing IEC aeronautical ground lighting (AGL) standards and can be used as a design specification.

Where certain aspects of design are specific to a particular type of system (e.g. series-circuit), these are supplemented in the applicable part.

IEC 61821:2011 applies to the maintenance of AGL constant current series circuits. This International Standard: - covers constant current series circuits for AGL installed at aerodromes and heliports; - concentrates on providing the safety requirements for the maintenance of an AGL constant current series circuit. It is recognized that AGL constant current series circuits of different design characteristics and parameters are in existence; - is mainly concerned with safety to persons by specifying the rules and fundamental principles for the maintenance of AGL constant current series circuits; - is not intended to apply to AGL primary series circuits supplied directly from a mains constant voltage source; - is not intended to be used for public street lighting, roadway lighting or any other installation requiring the use of constant current series circuits.

This edition includes the following significant technical changes with respect to the previous edition: a) addition of references to normative references; b) addition of notes in Clauses 5, 6 and 7; c) modification of pre-work procedures in item e) of 7.2.2.

This European Standard is intended to give general minimum frame requirements for units that are independent of the technology used for switching and/or monitoring of individual or group of lamps in an AGL series circuit. This European Standard • applies to the units that are directly electrically connected to the primary or secondary side of an AGL series circuit and are needed to provide the selective switching and/or monitoring of lamps, • does not cover communication protocols and application procedures, • does not treat system aspects that influence the AGL operation. NOTE These units may be used forming part of either a SMGCS or A-SMGCS to guide and/or control the surface movement of aircraft by means of visual aids.

IEC 61822:2009 specifies the requirements for a Constant Current Regulator (CCR) having a nominal output of 6,6 A for use in an aeronautical ground lighting constant current series circuit. However, CCRs may be manufactured which have a different power rating (kVA) and current steps than those specified in this standard in order to be used on existing circuits. This standard should be applied where appropriate for these CCRs. This second edition cancels and replaces the first edition published in 2002. It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) revision and update of terms and definitions; b) addition of new paragraphs, such as 'Nominal output current range and tolerances'; c) modification of some paragraphs, such as those related to 'Local control' and 'Remote control'; d) deletion of some paragraphs, in particular 'Power transformers' and 'Output current indicator'.

This standard specifies the characteristics of aeronautical ground lighting series trans-formers (AGLST) used in aeronautical ground lighting for 6,6 A series circuits, at a service voltage of up to 5 kV, supplied by constant current regulators up to 30 kVA in rating. AGL series transformers provide power to airport lighting luminaires or other loads (resistive) from their secondary circuits. The AGL series transformers provide continuity of the series circuit in the event of a loss of the load on the transformer, and electrical isolation between the primary circuit supplied by a constant current regulator, and the secondary circuit connected to the load under conditions defined in this standard.

IEC 62870:2015 specifies protective provisions for the operation of lamp systems powered by series circuits in aeronautical ground lighting. The protective provisions described here refer only to secondary supply systems for loads that are electrically separated from the series circuit.
