Through a large magnifying glass fitted in the deckhead of the A.I.C. room, bridge personnel could read the plot table and the PPI display. The front of the PPI display is shown with the mirror mounting frames folded back and in the stowed position. When in use, the frame was extended and a mirror would be inserted into the frame and positioned so the screen could be viewed from above. The Plot Table is shown with the dust cover in place.
