Yep - this is why we cant have nice things.
That's the problem and something every owner needs to be aware of - it WILL allow takeoff.
DJIs Geo system is extremely basic and for the most part doesnt show temporary restrictions or even some permanent ones. It will often let you take off and fly illegally.
You need to check yourself whether its safe to fly using the official Drone Assist app or equivalent online altitude angel data (
Drone Safety Map | Altitude Angel) or
Where To Fly Your Drone in the UK
Those display the actual legal no fly zones.
Relying on DJI Geo will mean you stand the chance of flying in a restricted zone without ever realising.
That aside, it takes a special kind of stupid to fly a drone at an airshow. Especially with literally 100s of "NO DRONE" signs around the crowdline. Its a deliberate action to fly not an accident.
Nobody should *ever* rely on DJI Geo alone to determine if a flight is legal from an airspace perspective.
