I noticed the no-fly zone around DC has been modified during mid August of this year. In looking at the map, it appears a new geofence has been put in place slightly off center from the original 15 mile no-fly area around National Airport.  Given that I have been flying on my property since February 2015, I was surprised to learn the new addition no longer allows me to start my phantom 3 on my property. Does anyone know if this addition is temporary. Or is this a permanent modification.  I have not been able to find any information about this modification or the reason for it. I would appreciate any information anyone may have on this new addition to the no fly zone around DC.

Thanks,
NS

Please email FlySafe@dji.com and they can answer all your questions.

The linked NOTAM list (notice to airman) has a few NOTAMs specifically for Washington DC. They outline no fly areas. I am unsure if DJI has included this in GEO.  It is always beneficial to review NOTAMS and TFRs (Temporary Flight Restrictions) prior to flying.
