The fog is ground fog. Those are not clouds in the sky. The drone is not even close to 500 meters. Anyway, your question isn't relevant to this drone test. The test was done to see how Auto RTH would behave as it piloted itself through fog. Initially it saw the fog as objects to avoid and returned home slightly erratic. During it's RTH it then made a B-line through the ground fog to the Home Point. When it got through the fog, it recognized it's take off point and landed directly on top of it. DJI has done a superior job with it's new Auto RTH feature. However, during some prior tests performed through the fog, the drone often stopped, turned and even went backwards a few feet as it performed it's Auto return in the fog. It saw the fog and the different densities of the fog as objects and would often times try to go around the denser areas of fog and even got stuck and stopped on occasion. In this particular video, the initial return home was slightly compromised by the fog, but not as bad as previous flights. The point you should take, is that Auto return home through dense ground fog can cause different levels of error to no error at all. Manual RTH may or may not be needed. But, a pilot should always be ready to perform a manual return in conditions with heavy ground fog. In most cases, as per FAA guidelines flying through heavy ground fog shouldn't be attempted. Final note: The identity of the pilot is unknown. |
