Hi Richard,
You can also checkout a detailed list of No-Fly-Zones inside of the app, so that you are aware of where you can or can't fly beforehand. In areas without 3D data, you can still launch in 2D Maps with Pitch and Camera mode. The focus of CoPilot is to make capturing video and images easier, so that you don't have to worry about piloting.
Hi Scotflieger,
While you would need special clearances from the UK CAA, it is possible to fly in that area with permission. Not sure how relaxed the UK CAA, but the US FAA has given us permission to fly in many restricted areas.
We are also integrating a new No-fly-zone feature to give you the most accurate no-fly-zones around the world, including London so that you know where you can or can't fly.
