Hi everybody,
In a vortex case, the worth action is to increase the power, you will accelarate the vortex. The Best way to leave the vortex is to move the drone horizontally to leave the vortex area. If possible, reduce the power at the same time. I'm helicopter pilot, the vortex is à known phenomena, I've saved all my crew many years ago with such an action and saved my Phantom 2 Too ;-)
You can detect a vortex when you descend straight down at a special speed (depending of V/S, weight, wind...) and then your drone is running wildly unstable. First reduce the rate of descend and if the drone is still unstable, immediatly move your drone horizontally to leave the dangerous vortex area.
DJI has updated the flight controllers by reducing the rate of descent, maybe a good attempt but it's impossible to make algorithms to avoid vortex that depends of variable data (Vertical speed, weight of the drone, number of motors, wind).
