I received a subsequent e-mail correction to this post that states that
the 747-400 does not use the same LCD displays as the 777, but instead
uses CRT flat-panel displays.  I stand corrected: I thought we were
putting the same LCD panels in our newest 747-400s, but apparently we're
not.  The display formats themselves, however, are almost identical on
both airplanes to enhance fleet comonality.  In fact, the new-generation
737s can have their LCD displays switched from analog-appearing
instruments like the older 737s to displays identical to the 777.  The
switch is made by loading display data into the computers from a set of
floppy disks and it takes only 20 minutes.
