(Ref. Fig. 003)
(1) The screen The MCDU display contains 14 lines, each having 24 characters. Of these 14 lines, the top line (line 1) is normally used as a title line or to display data to which the pilot does not have access. The bottom line (line 14) is the scratchpad line and is used by the pilot to alter the data in the data fields. Lines 2 through 13 are data lines arranged into six pairs (lines 2-3, 4 -5, 6-7, 8-9, 10-11, 12-13). Each pair of lines has a label line (the top of the two lines) and a data line. The data lines are adjacent to the line select keys, and the label line is just above the data line. The line pairs are referenced by line select keys as follows:
