3. The AL520 Configurable Multifunction Display provides an adaptable display of test data in aircraft instrument panels by combining a bright high contrast TFT LCD display with a programmable data processing unit Up to six gauges which are user defined can be placed on the display The compact unit utilizes standard Dzus turn fasteners and mounts in a 5 opening There are two phases of operation First in the lab the user programs up to 6 Pages of Displays each containing up to 6 gauges The gauges are driven from input signals supplied from various aircraft data acquisition subsystems These gauge displays are uniquely programmed each with selectable display type arcs bars totalizer or Tether Hover and selectable Units Label and Min Max tracking range color coding For some gauges the data can be displayed as either a sweep or a single pointer along with digital data value readout The resulting pages are stored in the Display s Nonvolatile memory The Flight Phase of operation involves simply using the Pushbutton keys located around the perimeter of the unit to select a Display Page to Reset the Tracking or Totalizer values or change Display Brightness Large keys with raised separators facilitate gloved finger use After one series of flight tests are completed the display can be reprogrammed to support the next set eliminating the need to buy unique specialized displays per mission FEATURES e User programmable LCD bas
