Ultraviolet (UV) Lasers for Aerospace Wire Marking

2006-01-21
HISTORICAL
AIR5468A
Ultraviolet (UV) laser marking for aerospace wire and cable is now a well established and accepted process. The purpose of this report is to provide general information on the technical basis of marking systems that apply UV laser energy to the wire surface. This includes materials for UV laser marking; the key characteristics of UV lasers suitable for this application, in terms of the mark process requirements and operational requirements; the various types of UV lasers which meet the general requirements for wire marking; and the generic components of UV laser marking systems. Subjects beyond the scope of this report include other wire marking systems not utilizing UV lasers; legibility; and contrast measurement. The contents of this document are for information only. It is not intended that it should be used as the basis for marking process specifications or standards, which are covered by AS5469 Wire and Cable Marking Process, UV Laser.

Aircraft Electrical Installations

CURRENT
ARP4404C
It is the purpose of this document to present design recommendations that will provide a basis for satisfactory and safe electrical installations in transport aircraft. This document is not intended to be a complete electrical installation design handbook. However, the requirements for safety extend so thoroughly throughout the electric systems that few areas of the installation are untouched by the document. It is recognized that individual circumstances may alter the details of any design. It is, therefore, important that this document not be considered mandatory but be used as a guide to good electrical application and installation design. Transport aircraft electric systems have rapidly increased in importance over a number of years until they are now used for many functions necessary to the successful operation of the aircraft. An ever increasing number of these functions are critical to the safety of the aircraft and its occupants.
