Hi there, What are these blue, purple and yellow lines around the airports that I find? lines

2

those are airspaces with mostly different frequencies to hand-off

3

So why the different colors? and when you say “frequencies to hand-off” what do you mean please?

4

yellow area means high density area of buildings if im right, not sure about blue line/area

Hi @TemperedPaper48!
I’ve moved your topic out of Bugs as it’s more a “question”. We only want bug issues in the topic you posted in.

I tagged your topic with “advice”.

Thank you!

hand off means you need to contact the controller responsible for traffic in the zone you are entering and report your specific information (such as altitude).

There is lots of information on line about these zones (and related flight charts):

This is another explanation of Airspaces.

The image is part of an actual aeronautical chart.

It’s actually a good question on the colors. I wouldn’t think the included VFR Map is any official representation of the true airspace yet as others have noted, the Blue here almost always represents controlled airspace, typically around busy airports.

When I pull up the LFPO area in ForeFlight - Uses actual navigation data - The purple and yellow boxes indicate restricted airspace.
