Every week I read about someone doing aerobatic with their drone and sometimes watching it plummet to the ground after a possible CSC maneuver. DJI should know this is not good for business, and of course reliability. If anyone from DJI is listening; how about preventing a CSC maneuver if the Visual Position System does not detect the ground within 4 feet OR the P3 is greater than 4 feet above the home point elevation, until the operator confirms on screen they want the CSC. This would allow you to fly and land the drone away from the set home point. You would need to ensure the VPS was on and working correctly, but the ultrasonic system could be tied to the lookdown camera to compare the two to ensure the VPS accuracy after every initial launch. If the VPS was good to go and didn’t see the ground within 4 feet OR the drone was greater than 4 feet above the GPS home point, there should be a very visible confirmation with an audio beep asking for the operator to confirm the shutdown. If in ATTI mode and the VPS was off, the confirmation should still come up. Real aircraft have all kinds of redundant safety systems to prevent mistakes, why not a drone. Just a thought.
