I am sure the following type of screen is all too familiar with you. Every long haul flight will carry a running screen to give passengers his aircraft's location, altitude, ground and head or tail wind speeds, distance to destination, local time, etc, and, as you can see below, even outside air temperature. I always wonder what good does the last piece of information provide. Say, at Minus 55 - what's the significance?
But something always puzzles me. Look at the picture below. Anyone who knows a little about Geography will tell you Singapore is on the east of Melbourne. But why is that in all maps all this nature, regardless of geography, the port of embarkation is always shown on the left and the arrival port, right? Unless the aircraft is taking the longer route flying around the other side of the globe!) This eerily reminds me of MH370!
Once in a SQ flight from Singapore to Melbourne, I saw that the destination in the display was "Sydney". I informed the steward and the mistake was duly corrected. However, if there was no alert, would the captain be actually taking the aircraft to Sydney, which is about 1 thousand kilometers north of Melbourne?
