This is an experimental monochrome precision face tube with electrostatic focus, magnetic deflection and used a P43 phosphor Tube but is very similar to the production unit fitted to the Civil HUD 2020 and 2022. The CRT narrow band P43 Phosphor operates with a Rugate notch Combiner Glass. .A Matching Card with deflection current feedback resistors would normally be fitted to the flat area. This CRT Assembly has 960mm cable (with connector) for its drive signals.
The reference document lists this as fitted to the ‘2022 HUD’ which was a variant of the HUD 2020™ fitted to the Boeing 737NG.
The 2020 system was designed from the outset to be expandable to show cursive, raster and cursive over raster displays such that sensors such as ALMW, FLIR or television systems can be considered. The HUD 2022 was aimed at producing a smaller derivative of the 2020 and work began in January 1997 with delivery of prototype hardware in 1998.
