What are the white lines on flight aware?

The white line is an estimated track while the aircraft was out of range of terrestrial ADS-B coverage. If you look at the track log, you will notice a “gap in available data” between approx 1450Z and 1750Z - this is the part of the track that corresponds to the white line.

The grey area there indicates that the aircraft is out of coverage ( an estimated flightpath is presented) for that part of the flight. The altutude graphic is part of the Skyaware map you have when you are feeding data towards Flightaware.

Three Stripes indicate that the person is the co-pilot or second in command. They assist the captain through flight planning and updating communication and flight mechanisms. Four Stripes insignia is worn by the captain; the one ultimately in charge of the safety and operations of the flight.

If every flight took the same trajectory, the traffic would be harder to manage. Another reason why planes fly in an arc is that since it is impossible to fly in a straight line on an airplane, an arc is actually the shortest distance between two points.

A second officer or a flight engineer wears two stripes, a first officer (co-pilot/second-in-command) wears three stripes, and a captain, also known as a pilot-in-command, is awarded four stripes.

Flight tracking enables travellers as well as those picking up travellers after a flight to know whether a flight has landed or is on schedule, for example to determine whether it is time to go to the airport.
