If so how do you know that you would not have been blocked.
Go to Google and type
DJI Flysafe Geomap. Then select the country you're in and the drone you're flying.
Below the map, select all the checkmarks for all the zones, also below there you have an explanation for every zone on the map by color and what restriction it will place on you when you fly.
Here's my more detailed explanation, all the zones from more restrictive to less restrictive:
- Red: Complete no fly zone, it will not allow to enter the zone at any altitude.
- Blue (Authorization Zone): Only allowed to enter if you have a certificate from DJI installed on your account and it is currently valid, there's a page to request those certificates to DJI.
- Grey (Altitude zone): only allows to enter and exit below a specified altitude (click on the zone in the map itself to see which altitude exactly), it will not allow to fly higher inside the zone. You don't need any special certificate or approval to fly, just be below that altitude, and set your RTH and Max Height below as well to not get stuck inside if you lose signal and the drone tries to RTH.
Recently they added huge, huge altitude zones about 50km around airports, if you click on them it will show 500m max, that applies only to
Mavic 3, because it's the only drone that can (without hacks) fly higher than 500m if you're not in one of them.
Orange (Enhanced Warning Zone): This one allows you to fly if you accept a responsibility warning in the fly app, it asks you when you approach it, or takeoff from it. You click the blue ticks, click approve and it takes off, other than that, no other restrictions apply
Yellow (Warning Zone): no flight restrictions, but when you enter or takeoff within it, it shows a small warning on screen, you click away from it and can fly.
Warning!
This doesn't in any way indicate if you can actually fly legally or not, always refer to your local drone map, DJI Flysafe only indicates how the drone will behave.
Very important!
Be careful to not get your drone stuck behind a no fly zone, because if you fly around a zone that is enhanced or stricter (above in my list) before actually flying into it and allowing the drone to fly in it, if then this zone is in the way of your RTH path and you have no signal, it will not cross the zone and get stuck in the other side, it might just hover, or even land, depending on the drone model.
When flying close to a no fly zone, always fly in just a bit, approve the warnings and turn off the controller, see if the drone returns or lands. Only then proceed to fly.
