This unit is made by Airshow www.airshowinc.com a division of Rockwell
Collins Inc. I agree the conversion to meters is overly accurate, it could
be rounded to the nearest 10 or 100 meters. These displays are programmed by
the engineers to display different things in different languages. I think
it's the software in the unit that makes the conversion overly accurate. The
altitude is not converted to feet because that's what is picked up from the
Air Data Computer that displays data to the pilots. The display in the
cockpit can display meters at the push of a button, but it's to the nearest
100 meters.

Subject: [USMA:36172] Altitude display in intercontinental flights
On the flight to and from Brazil, there's a display that shows the speed,
outside temperature, altitude, and time and maps at various scales. The
altitude is converted to feet, rounded to the nearest 1000, and converted
to
meters without rounding, which gives a false sense of precision. (At one
point it was showing 9144 m for several minutes.) I wrote to Continental,
but
received no response (nor did I get one to my message about orange juice -
on
one of the flights, but not the others, it was fake). Should I rather
write
to Boeing?
