I live within one of the circles... The dotted lines in the sky are quite annoying. But seriously, I share your pain.

My issue is with the display.  I can barley see the map due to the TFR circle over my property.  I'm not saying to rid it, but I'm allowed to fly withing the TFR as long as I do not break the 400' ceiling.  Therefore, I should have the right to turn off the TFR circles if needed.  Since I'm sure you don't live within one of these circles, it's easy for you to stomp your feet and be vocal for something that doesn't affect you.

"I don't think an option to turn off should be addressed or added

since they are regulated no fly zones anyway ,by turning off you knowingly break the regulations"

That is exactly right, and the operators are held responsible 100% of the time for their actions, regardless of what the copter does, so this choice should absolutely not be removed.  Use the TFR data and build a fence and call it good.

I also want to echo what David said - there are times where these activities are allowed, so, stop trying to turn the software in to big brother and start educating the operators better.

Just to throw a spanner in there. There have been instances where drones have been officially used at airports so I'd been keen to ensure there are no restrictions at all. Information / warning screens sure, but no restrictions.

@ Nathaniel

I submitted a Issue ticket at Github Mission Planner for a need to disable but provided another option.  Take a look and let me know or MichaelO if there is something I missed or if others feel there is something better to offer.

I think that sounds like a good compromise. It achieves notification but won't interfere with acceptable flight standards. Do you fly at one of the AMA sites I spoke of?

That's a good idea Doug

Comment by Doug Walmsley on November 26, 2014 at 6:01pm

I will recommend that the feature be enabled by default and operators may go into "Configure tab" and disable from view.  I do however feel that it should be automatically turned back on when the operator flies up to 400" AGL and once below that the circles will disappear.

yes that's true perhaps an altitude ceiling be imposed from the data collected for the specific areas reported, the markings would be still there and flight possible but a sort of geofence be applied for altitude in the effected area

Comment by Nathaniel Caner on November 26, 2014 at 4:18pm

Hi Charles,

NOTAMS etc. while informative are really directed at pilots of full scale aircraft. If we are staying below the 400' ceiling, as I know we all do right, this shouldn't be a problem. I don't want to start a debate here about the legal or ethical issues. As such I'm not going to respond further. I will say however that I agree with the spirit of your statement. It is the responsibility of each individual to be aware of any and all restrictions that effect their ability to fly in the NAS. As such I think having the ability to turn off the markings identifying these zones to be acceptable. It could be made like any GPS device these days. Every time you turn on MP and navigate to an effeted zone the markings are displayed, then you are made aware of the restriction and can act accordingly.
It should also be noted that there are two AMA sanctioned club fields in these zones within 25 miles of where Doug lives, he might even be a member of one of them. If model aircraft weren't permitted to fly at all within the zone AMA wouldn't sanction the site.
