DJI has removed geofencing from all drones, meaning no more unlock requests. But that also means there’s no built-in safety net anymore—pilots are now fully responsible for staying legal and safe.
How are you making sure you’re not accidentally flying into restricted airspace? What apps do you use to check airspace, weather, and temporary flight restrictions (TFRs) before takeoff?

The only way to fix that properly is with radar altitude. Are you suggesting drones should come with a RadAlt?
It could be done with data points, like how GPS works. It wouldn’t need an actual reading, just a calculated estimate based on location. Some drones already do this.
@Teo
GPS alone doesn’t give you an accurate AGL altitude—it’s just an estimate. Radar altitude is the most precise. The problem is, GPS errors can be off by several feet, which isn’t ideal for altitude limits.
@Micah
You could integrate LiDAR cloud points with GPS to get a better reading. It wouldn’t be perfect, but it would be more practical than installing radar altimeters in consumer drones.
DJI’s geofencing was inaccurate most of the time. Now it matches the FAA database better and provides a warning if you’re in restricted airspace. But pilots still need to check apps like Aloft for real-time updates and TFRs.
