Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

Introduction

This document is the standard of the LED (Light Emitting Diode) Taxi and RTO lights (Runway Turnoff Lights) for aerospace.

LEDs are attractive to users because of their lower power consumption and reduced maintenance efforts as well as their long operating life. However, Taxi and RTO lights require their light source to provide not only a large amount of luminous flux, but also high luminous intensity. Since recent LEDs achieve high luminous intensity, LEDs have come to be adopted as light sources of Taxi and RTO lights.

This document intends to establish a functional requirement set for modern Taxi and RTO lights which adopt LEDs as the light source.

In addition, this document is applied not only to the LED light source, but it can be applied also to other new light sources appearing in the future.

1 Scope

This document specifies characteristics and interface requirements for the LED taxiing light system.
