Replacement Incandescent Display Components and Assemblies

To meet the needs of aircraft operators needingreplacement display components and assemblies no longer available from their original manufacturers, Allied International, in association with IS Precision, a division of Inertia Switch, purchased the Wagner Lighting Display product line from Federal Mogul when the factory in Weatherly ,PA was shut down and the Wagner TRU operation was transferred to Champion Aviation in Liberty , SC. Inertia Switch's experience in manufacturing precision miniature electromechanical components for the aerospace industry made them ideally suited to bring the Wagner displays back into production. New transmission blocks manufactured at IS Precision have been supplied for the Mirage, the Nimrod , B-747, F-16 and others.

All Allied International/ Inertia Switch display components and accessories are new, custom-manufactured to the highest quality standards and fully conforming to all original functional, reliability and environmental specifications. Displays are available in 7-, 9-and 14-segment configurations, including Wagner-designed "special" characters.

As a source of reliable, high-quality replacements, manufactured in many cases from the original engineeringdrawings, Allied provides an outstanding resource to operators of aircraft and systems using incandescent displays. Maintenance and logistics managers can avoid cannibalization, loss of mission capability, loss of aircraft availability and the high costs of system replacement or modification forced by lack of spare display parts.

Although simple in appearance, segmented light pipe displays require the highest level of quality at each step of the manufacturing process to obtain the required brightness, contrast, legibility, and precision alignment in both plane and line.Display modules are supplied as a monolithic viewing block, often integrated with mountings and other control and switch subassemblies depending on customer requirements. The viewing blocks themselves permit individual lamp replacement.

Each monolithic display segment consists of the lamp mounting assembly, a heat sink, a transmitting block and a molecularly bonded filter which is the viewing surface. Each monolithic viewing block is backed by a heat sink and accommodates a lamp and associated light pipe for each display segment.

The block is then coated with the viewing surface which incorporates the critical molecularly bonded filter which attenuates incident light by absorbing both surface and internal reflections and increases the contrast between lighted and unlighted segments. Because the surface coating is of the same material as the transmitting block and tightly bonded to it, second-and even third-surface reflections are virtually eliminated.

Each step of the manufacturing process requires extreme precision and scrupulous quality control All Allied replacement displays meet or exceed the original equipment specifications including the requirements of MIL-E-5400, MIL-STD-810 and MIL-STD- 202.

Allied has acquired original engineering documentation for many displays in current use. Allied and IS Precision have also developed the capability to reverse engineer and manufacture complete assemblies and even CDUs to meet customer requirements for custom and special purpose displays. Even complex CDUs, ready to install, can be produced with a surprisingly short lead time.
