I am by no means an expert, however I took a look at the MP code looking for anything that might explain this. What I found may have nothing to do with the situation, however it might be a place to start. About 10 days ago there was a commit that added "TFRs" (TemporaryFlightRestrictions). You can browse this code addition  here as well as other history. I see other references recently to TFRs, so I think this is something that the devs have been working on for a while. Hopefully it's just something that made it in to the current release without creating an option to turn it off. I wouldn't be very pleased if I lived in an area that was 'blacked' out by one of these zones.

Hope they give us the option to turn it off soon :)

Have you posted an issue yet, if not post one here?

I assume you looked into going to an earlier version?

All I can say oh boy.... here we go.

@ Nathaniel and @Paul,

This crazy feature can not be turned off.  I went into Configure tab and deselected "Show Airports" and only the broken rings around airports disappeared.

I live inside the outer ring of this large and circle and can barely see anything under it.  This is annoying to say the least.

I believe that is identifying the Washington, DC Metropolitan Area Special Flight Rules Area (or the "ADIZ" Air Defense Identification Zone).

I don't think there is a way to disable it. You can turn off the airports, but I don't see a way to disable the display of these zones. It's interesting that it doesn't effect the Flight Planning page, just the Flight Data page. That really makes the Flight Data screen unusable for the Baltimore area in the zone.

It is the airport overlay, if you hover your pointer over the red circles they will show you the airport name.  Baically to show you when you are close to an airport. You can turn it off in the configuration tab, as detailed in this post:

I haven't seen this on mine, maybe a view setting?

What is this on my map and how do I turn it off?!?!?

It showed up when I downloaded the latest Mission Planner?

Where do you find the settings in MP ft modes

Comment by Mark Aylward on October 27, 2014 at 1:34pm

ok so now I am stuck at getting the R7008sb to talk to PixHawk for my initial set-up.  Do I get a PPM encoder and use the 8 ports into PixHawk vai the encoder or is there another solution yet?

Can someone help on my posted question?
