I was cruising in our Airbus 321 this morning to Dallas when I wanted to check our flight map and the following screen came up. Note the figure against distance traveled. Throughout the flight, the system kept updating the distance, but always gave it till the second decimal digit in miles!!

Think for a second. That makes no sense right? A second decimal place in miles would mean about 50 feet. The plane itself is three times as long. At 31,000 feet height at a speed of 500 mph, it takes us less than a tenth of a second to cover a second decimal in miles.

It is an irony that my flights get delayed by hours but I am given my flight progress in less than a tenth of second accuracy!!
