On the map a coloured line shows the route of the aircraft. Purple colours indicate cruising altitudes. White colours indicate the plane is on the ground. As a plane takes off, the colours change from white, to yellow, to green, to light blue, to dark blue and finally to purple.
For flights that are no longer in our coverage area, we may estimate their position for up to 240 minutes. These flight tracks are shown as black dashed lines. Read more about estimated positions on Flightradar24.

Green is from a reported position.The white with the circle is an estimated position since the aircraft might be outside of the area that FA gets radar data for.
A dotted blue line is the intended route based on the filed flight plan, The green is the actual route flown based on ADS-B. If you view the whole flight on FA and zoom in real close you will see both lines as the flight pretty much followed the filed plan.

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.
