The A380s operated by Emirates have a Rockwell sourced information system, including a fake window display with fake instruments: an artificial horizon, a compass, an altimeter, an indication of vertical speed. I’m sure it’s not very accurate and lags, but it is intermittently interesting for the layman. However, I have not after many flights been able to figure out one indication, a small number accompanied by two arrows which sometimes reverse direction, which I cannot correlate with any movement of the plane. I have circled it in the picture. Does anyone know what it is supposed to mean? The whole things looks well engineered, so I assume it’s meant to mean
something.
