Here is a clear picture of what it looks like:
The IS&S Flat Panel Display System (FPDS) is an easily installed cockpit upgrade for the Tristar L1011 aircraft. The Primary Flight / Navigation Displays are designed to replace the existing EADI and EHSI display, altimeter, airspeed, vertical speed indicators. The Engine Instrument Display System (EIDS) is designed specifically as a low-cost upgrade of the Tristar engine instrument cluster, replacing primary and secondary engine indicators.
This easily retrofitted replacement system is compatible with the existing cockpit configuration. It provides all existing primary flight, navigation, engine related parameters, hydraulic indication, and flap and trim position indicators using five (5) AMLCD (Active Matrix Liquid Crystal Displays) in lieu of over 73 LRUs. Its unique design concept permits accelerated modification of graphic display formats, and as importantly, rapid certification.
