Yorkshire UK | The newer DJI models have an onboard database of places you can't fly or can only fly at reduced altitude, and you wouldn't be allowed to take off - however for specific locations you can acquire a code from DJI for a one off flight perhaps with restricted altitude. Most users won't need worry about this but you might see it checking for updates periodically, or saying it hasn't been able to update if you don't go online. There can be brief complete shutdowns over a certain radius due to events nearby (e.g. Presidential visit!). If the app is kept updated it will *know* about these. Again most rural users will see none of this.
The drone will have the maximum altitude at 400 feet by default but you can simply change it in the pp to a maximum of 500m about 1600 feet If there's a mountainside you can go much higher than 400 feet above your take off point without going 400 feet above ground so not illegal at all. In general 400 feet is more than enough, it's rare I go above about 200 feet, this is enough to (e.g.) avoid spooking cattle in most cases. They have got a good deal quieter with redesigned props and motors the last couple of years. |
